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.

Don't go here
Dude basically robbed me of $250 for 5 minutes of his time. I'm a former trauma one emt. I paid the money to be told what I already know and stretch. The women I dealt with were nasty in the office. If you can't have compassion get out of healthcare. Didn't get the x-ray I paid for. Also you basically have to write a book to be seen. Would not recommend.

Surgery went well and as expected. Honest with expectations of how long I would be in a sling and expected recovery.

I have trusted Dr. Koss for many years with my surgeries. Dr. Koss is very informative regarding the procedures and does let you know what to expect regarding the after effects. Dr. Koss is my "go to" for any thing concerning orthopedic.

I had a very positive experience with this provider. The only issue i had was with the delivery of my after surgery recovery brace but that was through a third party. Doctor Koss was very thorough in his explanation of my injury, expectations for surgery and rehab. I would recommend them to anyone!

Dismissed my pain, dismissed what I was saying…
Then cancelled my 6 month scheduled surgery claiming I’d gained 20-25 lbs in the 6 months I was waiting. None of my medical records from the past 9 months support his claim of weight gain. Just walked in after 6 months on his schedule and basically said I was too fat for the already scheduled surgery…

So glad that I saw Dr. Koss for this matter. I was told by another surgeon that the Rotator Cuff was "Too Torn to Repair" and he sent me on my way. Dr. Koss, however, was able to repair it successfully. Very thankful and happy that I was able to have him do the surgery!

Dr. Koss went through a thorough process of treating my knee for several years with various methods. Once they no longer provided relief, he recommended a partial knee replacement. That went smoothly and I have had less pain and more range of activities.
