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.

I have seen Dr. Ferrell since 2016. He makes my knees bionic. Much better than a replacement.

Dr. Ferrell is the best.
Dr. Ferrell has a phenomenal bedside manner and you never fell rushed. He takes the time to listen to your concerns and gives many options for treatment. I love that the practice can give options that many doctors do not perform. I have been with him off and on for several years. I have referred many of my family and friends to him as well as patients.

I refer everyone I know to Dr. John.
I’m an avid runner and have experienced an injury or two over the years. Dr. John assessed my situation, treated me and got me back on the road to run the NY, Chicago, and Berlin Marathons.

Dr. Farrell is outstanding
Dr. Ferrell is the BEST diagnotician I have ever encountered. I highly recommend him to anyone who will listen. He identifies the root cause of an issue which saves tremendous time, pain, energy, aggravation, and money. My experience with him has proven this time and again. It is why I keep going back for the past 8 years.

Knee pain and stiffness
Dr. Ferrell takes time to listen to his patients and do everything in his power to help alleviate troublesome issues. Dr. Ferrell and his physician assistant Barry are wonderful with helping solve health issues without surgery. Their knowledge and expertise compliment one another and my experience has been phenomenal under their care.

Excellent, forward-thinking doctor w great staff
I've seen Dr. Ferrell a handful of times now and he always takes my worries seriously and takes time looking and answering questions. But his differential is that he's not one to make a problem where there isn't one or to prescribe short-term gimicky fixes where there isn't room for one. Many doctors will see a slight abnormality in a test or imaging and jump to the worst, but Dr. Ferrell has been noticeably careful to differentiate between causation and correlation in his diagnoses. He and staff are up to date with the latest findings in the field and don't think like surgeons but rather are holistically in tune to the current directions of the fields of their colleagues in physical therapy, etc. He's quick to remind that far more often than not, the body can heal itself with changes in our habits and improvements in the way we move. And in the occasional situations when this fails, he and ROSM are on the cutting edge of offering treatments to break the plateaus and restart healing.

Always a good experience
Dr. Ferrell has fixed three torn ligaments and just did PRP on a fourth. I expect I’ll be 4/4 thanks to him.
