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.

Exceptional recovery from total knee replacement
I am six weeks out from total knee replacement (TKR) by Dr. Gregorian, and aside from some residual nighttime achiness, the results have been nothing short of phenomenal. I progressed quickly from a walker to a cane within days after surgery and have not used any mobility aids in over a month. I can easily perform all activities of daily living, and am able to walk my dog two to three miles daily. Best of all, I have zero knee pain when ascending or descending hills or stairs. Dr. Gregorian has been my orthopedic specialist for the last two years of my osteoarthritis journey, and he has always taken whatever time was necessary to answer all my questions and concerns during appointments. In addition to outstanding patient interaction, his professionalism and medical knowledge are exceptional. I am grateful to have found Dr. Grigoryan, and cannot recommend him highly enough to anyone seeking treatment for an injury or debilitating joint condition.

Worst care I ever had
I went to Dr. Gregorian and was in extreme pain, I couldn't sit down, could barely walk, and was bed ridden. Dr. Grigorian prescribed an immunosuppressant which did nothing to control pain. After being unable to stand up the next day and having stayed up all night, I called his office in the morning and told them I was in excruciating pain and couldn't even get up. I didn't received a call back all dayso I called again at the end of the day. I got the answering service and was told a Rolling Oaks doctor on call tonight would get back to me, this was at 5 pm. By 8 eight pm nobody called back. I called again at 8:30 pm in such extreme pain that I asked again to speak to a doctor. Dr. Grigorian did call back and to my shock prescribed anti-spasm, muscle relaxer, and an NSAID. I suffered greatly, an it turns out I have 2 herniated disks!! Stay away, he didn't even go over my MRI when I did a follow up. Very unprofessional, stay away.

Friendly, Professional and Detailed Orthopedic
Dr. Grigoryan is professional, caring and took time to answer all of my concerns. I had fallen hard on my knee. He was really careful examining it. He reviewed the X-rays with me. We agreed on a plan of care. He fit me for a knee brace. Dr Grigoryan told me to call him any time with questions. I felt much better when I left.

Awesome! Got an appointment same day & got treated
Got an appointment same day & got treated on the spot. Knee was filled with fluid and got drained same day. Not a big fan of needles but Dr. Grigoryan was super cool and careful. It's been a day since the procedure, and I feel great and walking way better!!! Totally recommend going to visit Dr. Grigoryan. Nice guy and knowledgeable! Thanks!

The Best Orthopedic Surgeon around!
I was referred to Dr. Grigoryan for a total hip replacement. And I am so happy that I was. Due to having congenital hip dysplasia I was forced to have the hip replacement done at the young age of 37. From my very first consultation with Dr. Grigoryan he put me at such ease. He took the time to answer every one of my questions. He explained everything in words that I could understand. I had been experiencing debilitating pain for 5 plus years so I knew this surgery was my only hope at having any type of quality of life. The surgery went very smoothly. My surgery was performed at 7:15am and I was home the same day by 4:00pm. Dr. Grigoryan performed an anterior approach and because of that my recovery also went very well. I am now 6 weeks post op. And returning to work next week. I can never thank Dr. Grigoryan enough for what he has done for me. He gave me my quality of life back. He gave me the ability to keep up with my 8 year old daughter. He is the BEST orthopedic surgeon ever!

Right Knee Replacement
11/09/2021 date of surgery. I am a 79-year old male, pain in my knees was so bad it would make me cry. Due to bone-on-bone condition Dr. Gregorian replaced my right knee. Three months post-op and I am pain free, have total range of motion and it already feels like a normal knee. I could not be happier with this outcome by Dr. Gregorian. I was released at my 3-month appointment. He is very easy to talk to and gives his patients his full attention. Five Stars for Dr. Gregorian, a 5-Star orthopedic surgeon.
