5 stars! Make it 7! 10! Everything you want in a doctor visit. Super friendly, fun sense of humor, incredibly great staff, and feeling important as a patient.

Dr. Cohen and his staff are excellent. They are professional, knowledgeable, friendly and show great customer service. Dr. Cohen has the latest equipment and technology, and is definitely a subject matter expert. He has treated both of my 58 year old shoulders that are showing their usage over time. We started with a steroid treatment which worked well in one shoulder but did not resolve the other. Now am starting a PRP treatment as a next step. I feel well cared for under him.

Very percise evaluation and honest supportive recommendations. If you are considering PRP or Stem Cell procedure stop by and let Dr Cohen give you an evaluation.

A refreshing honest look at my prognosis, ending in excellent news about the healing/maintenance of my knee. I will continue to see Dr. Cohen for my orthopedic needs.

Great experience would highly recommend them

Dr. Cohen is very professional and knowledgeable. If an issue arises he has the knowledge and shares the details with the patient and what to expect. I would highly recommend Dr. Cohen for any procedure at Coastal Regenerative Orthopedics & Wellness Center.

I can highly recommend Dr. Ron Cohen and his office staff for anyone having joint discomfort. I would give him more stars if allowed. He is extremely personable, kind, and knowledgeable.

Dr Cohen was very timely, personable, professional, thorough & knowledgeable. He did not rush me. He was a good listener. Unfortunately he was not able to offer anything to help my particular problem.

Have had two stem cell procedures over 10 years. Excellent results. Recently did PRP. Would not go to any other Doctor.

Exemplary care of my orthopedic needs.

Outstanding experience - Dr. Cohen is upfront about procedures and humorous with patient care, making the entire procedure from evaluation to stem cell injection painless (ha ha) and worthwhile. Looking forward to my continued pain free knee! Staff Candace and Jackie also very enjoyable and fun!

This is my second stem cell procedure in an 8 year span. Dr Cohen did both knees 8 years ago and will be doing just one knee this time. My other is good. I have enjoyed how fast I was able to get back to my normal daily routine. He is the best and informative doctor I have had the pleasure of knowing. I world highly recommend his services.

The only doctor I trust! He is honest and oh so experienced! Great bedside manner.

The entire team is so personable and friendly. They all do a great job puttimg you at ease. Dr. Cohen is extremely skilled and professional.

Fantastic good service and explanation of the subject issue.

Dr. Cohen is everything that you would want a caring doctor to be even though I was not a good candidate for stem cell. He was honest with me and I appreciated that so much I would recommend him to anyone.

Dr Cohen and his staff are great. He did a super thorough exam and ultrasound to find the source of my hip pain. The PRP injection makes a huge difference in my ability to hike and be active. I had a PRP injection in my opposite hip almost 2 years ago and still benefit from increased strength and decreased pain on that side

Dr. Cohen is outstanding. His attitude is great. His explanation is superb. He takes the time to guide you through a treatment plan that suits your needs. The staff at his office were of the same quality. I've never been treated better.

3 knees procedures over 10 years. 2 stem cell, 1 PRP. Trust and respect Dr. Cohen and his team. An excellent, professional, caring experience. I get a comprehensive understanding of my knee issues, with realistic expectations of what the procedures can do for my particular case.

5 procedures, over 10 years. Dr. Cohen and his team are fantastic!

Always caring, always helpful!

I highly recommend Dr. Costanzo! She is phenomenal and has an incredible bedside manner, with amazing listening skills and impeccable attention to detail. She explained my diagnosis and treatment options, and thoroughly walked me through the selected procedure as she was performing it. You can tell she truly cares about her patients and genuinely wants to help them. Dr. Costanzo never rushed, patiently answered all my questions and addressed all my concerns. My situation was complicated but she simplified and helped develop a solution on the spot that would eventually heal me! I'm thrilled with the results after just one session! Her skill are truly impressive. I appreciate the relief after struggling with back pain for nearly a year. She actively followed up several times after the procedure and patiently offered many solutions to make me feel more comfortable. Dr. Costanzo’s skillful and effective approach has been life changing for me! Overall, extremely impressed with Dr. Costanzo and the amazing clinic staff, who are very friend and always willing to help any way they can.

The office is clean and modern. The staff were both friendly and helpful. Dr. Cohen explained the treatment (PRP) thoroughly. Although the procedure can be uncomfortable he made it as pleasant as it could be. He is so caring and knowledgeable! It doesn't hurt that he is absolutely hilarious! I would highly recommend him to anyone!

I highly recommend Dr. Cohen! He has a great bedside manner, he listened, he explained his diagnosis and my treatment options, and thoroughly walked me through the selected procedure as he was performing it. He also spent almost an hour with me versus the typical 12 to 20 minutes you get with a doctor. Overall, very impressed.

Had excellent 4 month follow up. Very informative, good plan going forward.

I am a patient with a lot “situations” Neck, shoulder, carpal tunnel, hip and bad knees to mention the most relevant. I have sought help from other doctors, both in the United States and in Mexico, and I had not found one who could understand and help me with all of these situations. Dr. Ron Cohen did And from my first visit, I was very satisfied and I knew that he would be able to help me and that is how it has been. He explain to detail every one of my concerns. I am very thankful that I find him. All his staff is amazing.

Dr. Cohen and his team are very professional and friendly. Dr. Cohen is an expert in this field and provided excellent and personalized care. I’m looking forward to getting relief of my pain.

Dr. Cohen is an intelligent, thoughtful physician. He has listened carefully to me. I have had painful CMC (thumb joint) osteoarthritis in both right and left thumb joints for over three years. Under the direction of various physicians I’ve had physical therapy and steroid injections. One year ago I had right hand CMC arthroplasty surgery by an esteemed and ‘un-named’ San Diego hand surgeon. The post op pain was excruciating an did not appreciably subside after 6 months. Upon my last visit I was told the pain had nothing to do with his surgery and was advised to undergo yet another surgery in the same area of the right wrist. I was also told to take two Tylenol and two ibuprofen along with a glass of wine at night for the pain. I felt very hopeless. This is when I found Dr. Cohen online. I was surely ready for PRP/ stem cell therapy. I had decided against any more surgery. Six months ago Dr. Cohen provided stem cell and PRP therapy for my left CMC joint (this was the wrist that had not had surgery but was also very painful). I am six months out from Dr. Cohen’s left wrist stem cell/PRP therapy. My left wrist is virtually pain free I am one year out from my right wrist surgery and still experiencing considerable pain. Dr. Cohen has agreed to help me with my right wrist. I can’t adequately describe what a gift Dr. Cohen has given me. I have a pain free left wrist. After three years I can write and my hand no longer shakes from pain. I have very positive thoughts that he may be able to help my right wrist. Last thing: Dr. Cohen is very kind and has a good sense of humor. The office is very welcoming as well.

It has been 8 years since my first stem cell treatment. I now have torn manicus. Dr. Cohen will repair this without a problem. So nice to have it done and back to having fun. Best doctor to have.

I only wish I had gone to Dr. Cohen long ago! It’s obvious he loves what he does to help people, and the amount of time he spent with me was like no other. I appreciate his education and explanation. Great experience with the entire staff.

Staff and doctor very friendly and informative. Great relief of shoulder pain

The whole office is so kind and friendly. It's very comfortable atmosphere

After my successful stem cell procedure on both my knees in August/23 I decided to have PRP booster in November/23. As with my other procedures, Dr. Cohen and his staff continued to exhibit their knowledge and professionalism. Charles "Bud" Kasper

Dr. Cohen, is very thorough in his examination and took his time to explain.

The clinic staff and Dr. Cohen were very positive and polite. The procedure was as painless as possible, and each step was explained. I appreciated the care and comfort provided by each of the team.

Dr. Cohen’s PRP treatments I had for the shoulder improved my pain and quality of life. He explains his findings and proposed treatment options well. All the staff are very nice and helpful.

The entire team at Coastal Regenerative is amazing! They focus on care and getting you pain free! Cannot say enough about them!!

Excellent! Very thorough and kind! Staff is great!

The doctor show me what was wrong, explained the strategy, and answered my questions. I wish all doctors did this.

This was my third visit over 10 years. I can’t say enough about the professionalism of Dr Cohen and his staff. My visits require my flying coast to coast so this says it all. The warmth, the laughter, and the positive results are all part of the experience in choosing a great doctor.

Entire staff is caring, professional and knowledgeable. I have received more confident care at Coastal Regenerative pertaining to my orthopedic issues than I have ever received in other medical settings.

It was such a pleasure to talk with Dr. Cohen again regarding my ongoing knee issues. He was so attentive and after checking all of my records was able to give my an informed and thoughtful decision as to what we can do next! So appreciated!

Very thorough and thoughtful

Appreciate the advice Dr. Cohen gave. I am a repeat Regenexx patient with great results.

I was so impressed with the level of care and analysis provided by Dr. Cohen and his team. After extensive evaluation, Dr. Cohen gave us a comprehensive plan to help me. He spent a great deal of time explaining the procedures - including showing us some of the equipment. Overall, it made me feel quite confident that Dr. Cohen is not only an expert in his field but that he cares about my well being. I would highly recommend Dr. Cohen and his team!

Very informative Dr Cohen was honest and very thorough

I highly recommend Dr. Cohen and his practice. I was able to get in quickly for an evaluation and he and his staff took good care of me. They are all very kind, attentive, caring and their experience and expertise shows. Dr. Cohen made great referrals and follow-up was quick and seamless. Thank you for your time and care.

DrCohen was very informative and spent the time explaining my right shoulder situation as well as answering any questions I had I was very satisfied with this appointment and will recommend him to others Tom Pappas

Dr Cohen is great. He is personable and kind. His exam was very thorough and he explains the X-rays and sonsgram completely. Then he is honest in his diagnosis and advice. The office gals are all friendly and efficient. The office is clean, modern and well decorated. I would highly recommend him. I have had both stem cell and PRP procedures from him over the past 6 years. All have been great experiences.

Dr. Cohen and his office staff are fantastic! His staff are always friendly, caring, and attentive to the needs of their patients. Their follow up with a patient prior to and after a procedure is also very good. Dr. Cohen has been treating me since 2018, and although there are other physicians who specialize in restorative stem cell therapy much closer to where I live, I would not consider changing physicians. I know Dr. Cohen and his staff will treat me fairly and with respect. Dr. Cohen is a knowledgeable, experienced, and dedicated physician who is patient and caring. I have been a patient of Dr. Cohen for the past five years. His initial stem cell procedure on my knee and follow up PRP injections have replaced the need for another knee replacement, which I am very grateful for. I highly recommend Dr. Cohen’s office to anyone seeking an alternative to surgery.

I've been seeing Dr. Cohen for years and appreciate his professionalism and knowledge. He has great experience with orthopedic regenerative medicine. I would not hesitate to recommend him to anyone.

Dr. Cohen and staff are the ultimate in caring and knowledgeable professionals. Over the years I had several stem cells procedures performed by Dr. Cohen ( both knees, and shoulder) with complete success and 100% satisfaction. As an older athlete, and because of the positive results of these procedures, I see a long and healthy future in my everyday and athletic endeavors. Thank You Dr. Cohen.

This is the most compassionate doctor I have ever been to. The experience was extremely positive and gave me hope for the future. And she is wildly intelligent, and knows more than any doctor I’ve ever met. But it is her bedside manner, her compassion that sets her apart from everyone else. Completely blown away.

The office is comfortable, and the staff was helpful answering my questions. Dr. Cohen is a gentle, thorough Physican willing to explain possibilities with his procedures. I plan to pursue this medical talent with my knee problem in the very near future.

Great consultation and explaining of the process.

Dr. RONALD COHEN explained the procedures he does in a very thorough manner. He let me watch the ultrasound while he was performing the images on both of my hips. He explained what he was looking at and what his findings were. At the end of the consultation he recommended hip surgery on one of my hips. Very honest and caring doctor. He also spent about an hour with me, far more time than my regular Orthopedic doctor ever gave me.

It was good

If you have an orthopedic condition, I cannot recommend Dr. Cohen enough. I have seen him for 7 years and he never disappoints in professionalism, competence or caring. I found his diagnostic strategies far exceed any other sports medicine or orthopedic professional. Seeing your joint in motion with ultrasound is everything to me! I would NOT have an aspiration or injection done blindly ever! He does not oversell anything. Thank you Dr. Cohen!!

Very knowledgeable and explained my diagnosis and options clearly. His staff assisted with the visit as well and did a great job.

Thorough and complete examination from my prior work with Regenexx. Dr. Cohen is a great addition to my options in treating my physical health.

I had a fantastic experience at Coastal Regenerative Orthopedics and Wellness Center. The staff was incredibly friendly and knowledgeable. Dr. Cohen provided exceptional care and explained the stem cell therapy and PRP thoroughly. Coastal Regenerative Orthopedics and Wellness Center's stem cell therapy and PRP treatment did wonders for my rotator cuff tear. I highly recommend Dr. Cohen and Coastal Regenerative Orthopedics and Wellness Center

My skin work experience with Mahdis was very good. She is very professional. She explains the process patiently and answers all questions you may have. The result of microneedling was better than my expectation, and I highly recommend her.

Very caring staff and Doctor. They took their time explaining my situation and reviewed future treatment if needed. Would definitely recommend them and use them again

Dr. Cohen and the staff @ Regenerative Ortho are second to none. This is my third procedure with them and that won't be my last.

Superb people

I highly recommend Dr. Ronald Cohen and his team at Coastal Regenerative Orthopedics for stem cell procedures and beyond. We are super happy 3 months after the procedure where I had my bone marrow stem cells injected into my knees and shoulder. I can now walk up and down my stairs "noise free"!!!!! No more bone on bone grinding. My right knee has a torn ACL, and after receiving a majority of the stem cells, my knee has been healing well with much more strength and stability. I had also stem cells injected in my right shoulder which is also feeling much better overall and I have much more range of motion and strength than I did before. My left shoulder had PRP injections and is also noticeably better after a labral tear. Both shoulders had labral tears and lots of inflammation/tendonitis/bursitis. Now both are feeling much much better!! I'm surfing better than I have in years and finally back on my board at about 90%. I look forward to the next 15 months where I'm going to be climbing up to 100% and catching huge barrels in Bali!!! I'm 38 and going for my dreams stronger than ever, all thanks to the help of Dr. Cohen, Regenexx, and my own body's natural healing power (aka Thanks G-D). So super grateful! Thank you Dr. Cohen!!!!

Staff was friendly and attentive. Dr. Cohen was thorough and answered my many questions.

After months of seeing to orthopedic specialists and physical therapy, I think I have found the professional level of experience to diagnose and treat my aging knees. Dr Chohen performed an extensive exam and spent considerable time with me to discuss my knee challenges. I look forward to the prescribed non-surgical treatment!

Outstanding experience with an excellent, kind, and skillful physician!

As always, Dr. Cohen was very informative and spent the time needed to discuss the issues. Looking forward to solving some problems.

In early 2021 I discovered the Regenexx website while researching orthopedic alternatives to surgery. After my initial consultation with Dr. Cohen, I scheduled a stem cell procedure to improve rather than replace my knees. Best medical decision I've ever made. Follow up PRP treatments have helped me stay active and virtually pain free. His thorough, professional approach exemplifies what all patients seek in their doctors. Thank you Coastal Regenerative!

Dr. Cohen and his team are excellent, knowledgable, caring, personable, and they take their time to thoroughly engage with the patient. With a torn tendon (ischial whatever-it's-called) it hurt to sit for very long. An ultrasound showed the two microtears in the tendon. With a PRP injection, about two months later, a second ultrasound showed the two microtears about 75% healed. Symptoms are diminishing as well. Some doctors might have performed a second PRP upon the patient's request, but Dr. Cohen and his team are interested in health, not raking in profits or merely appeasing a patient's wishes whether relevant or not. I highly recommend Dr. Cohen and his team!

Very informative and professional. Procedure was explained as it was done and now , a day later I am more comfortable and have a greater range of movement

Dr Cohen has performed several procedures on my knee over the past 8 years to avoid knee replacement. He initially performed a stem cell procedure which we have followed up with alternating PRP and hyaluronic acid injections every year. The procedures have improved the condition of my knee and have enabled me to maintain an active lifestyle. Dr Cohen has been very informative as to what his recommendations can and can’t do. He operates with great expertise and precision and is very trustworthy! There are many ‘snake oil’ salesman in regenerative medicine, but Dr Cohen can be trusted! I highly recommend him based on the excellent results he has achieved on my once arthritic and degenerating knee.

Great

Relaxed and informative. Dr. Costanzo is top rated in my book. She works together well with Candice and they thoroughly and accurately achieve a very professional atmosphere and treatment environment. Dr. Costanzo was eager to answer all the questions I had regarding aftercare and activities, about nutrition, things to avoid and things to do.

Just wonderful from the start to finish! Wonderful helpful and knowledgeable staff took wonderful care of me!!

Mahdis is professional and experienced. She made sure I was comfortable and at ease and she did a great job

Amazing experience! Dr. Cohen is certainly an expert in this industry. After 13 years of my searching for answers to my pain after a car accident, he’s the only one who has figured out what my injuries are. He was able to address the pain more than anyone else ever has in those 13 years. 70% of my pain is gone. And that’s just with the first round of injections. Truly anyone who is in pain and hasn’t found the right answers, if you go to Dr. Cohen it’ll save you tons of time and suffering. Wish I had found him in year one! Thank you, Dr. Cohen!

I’ve just started the weight loss program. I haven’t changed anything about my diet or physical routine and have already lost almost 7 lbs. it works!!

Dr. Cohen is a very kind and respectful physician. Not to mention the treatment he gave my thumb joint has made an amazing positive improvement already! Dr Cohen’s staff is just lovely as well.

Dr. Cohen explains everything very well and gives the best of care. My husband and I have had great results with the platelet injections in our shoulders. Highly, highly reccomend this this treatiment and Dr. Cohen and staff!! Avoid surgery and let the body rebuild!

Excellent feed back from doctor to patient. Therapy's are painless and work. Results are virtually immediate and continue to improve for the ailments you are trying to treat. Having been a stem cell recipient over ten years ago on a lateral meniscus problem, things still in really good shape. This latest PRP with A2M as a serum has just been administered for some ligament and tendon problems and things are looking very good and relief from pain has been for me, immediate.

Dr Cohen took time to explain everything and bottom line my joints feel so much better!

Dr. Cohen and staff are amazing!! Please consider a consultation before getting surgery. I was told by my Dr. at Scripps that a hip replacement was my only option. I am so glad to have found Dr Cohen, I received bone marrow and PRP injections last week and can walk pain free and everyday have more range of motion. Thank you Dr. Cohen and team for everything.
