Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

In Great Hands!!
Needed double knee surgery at a very busy time in a very busy hospital in Philadelphia. Dr. Deirmengian made it a priority to fit me in operate on both knees the day after I was injured. Progressing nicely. Job well done!!!

Double knee teplacement
I had both worked with Dr Dermengian so I was familiar with his work, I also asked other medical professionals and they also highly recommended him. My experience was great, he was friendly and approachable as was his staff. I had been given a direct contact with his nurse and never had to wait for medication prescriptions. My PT was very impressed with how nicely my scars healed

Amazing Surgeon!!!!
Dr Deirmengian is a top notch surgeon! He did left hip replacement on me 2 months ago. I feel like a new man. He is definitely the best in his field. I highly recommended him if you have hip or knee problem. He will be doing my right hip later this year.

Dr. Deirmengian is number one in orthopaedics.
Dr. Deirmengian did my left hip replacement with fantastic results. I have great faith in his capabilities. He will be replacing my right hip soon. I highly recommend him for hip replacements! He's thorough, patient and has a wonderful bedside manner. His results are with minimal scarring and quick recovery. His team is wonderful too. The communication with his team is impeccable!

Hit the Jackpot with Dr. Deirmengian
Dr. Deirmengian was recommended to me. From the first time my husband and I met him, we had complete confidence in his work. He was thorough in his details concerning my knee replacement. He has a wonderful staff with him at his office and on surgery day. Had surgery on Aug. 12 and my follow-up with him on Aug. 29. He was pleased with my PT. Scheduled my other knee for January 2023. Highly recommend.

A Compassionate Surgeon
When I first met Dr. Deirmengian, I felt comfortable right away. I didn’t feel rushed during my visit, and he answered all of my questions without staring down at the computer. My hip replacement went smoothly, I had no bruising and minimal swelling. After two months, my scar is barely noticeable. I I have decided to go through with my other hip next month.

Excellent Care
I’m a 76 year old who was petrified to have hip replacement surgery. DrDeirmengian did the surgery and today three weeks out I couldn't be more pleased with the results and my progress. Don’t be afraid like me, let the Doctor do his job and you will be better again !! Thanks Doc!

Definitely Competent
Dr Greg Deirmengian is a very caring surgeon and has a fantastic team working for him. I went to see him in King of Prussia instead of going all the way to NJ office. They have another office in Limerick Pa if that helps someone else. As soon as I met him I knew he would solve the problem with my knee. He is confident and very capable plus kind. He also explains everything and will take the time to answer all your concerns. I really appreciated him and his care. Sincerely, Sue P.

Hip replacement
Dr. Deirmengian is the epitome of what you expect from your dr. I was very apprehensive to go see him. Thinking I was going to get cortisone injections, Dr. Deirmengion explained I was bone on bone for my hip, resulting in total hip replacement. I must say I feel like I have a whole new lease on life, my surgery was not as bad as I thought it would be. Latifa who works closely with Dr. D explained everything from surgery prep to what to expect after the surgery. She was no further than a phone call away for any questions pre and post op. I am 5 weeks post op today and I am feeling really good. I can't recommend Dr. Deirmengian and his team enough. 5 stars for sure if I could give 10 I would.
