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.

Highly recommended!
All of the staff and Dr Kolnik are knowledgeable and friendly. He has my gastro issues under control. I highly recommend this practice!

Awesome GI Doc
Dr. Kolnik tells you exactly what's up. He is friendly, easy going, and smart. Whenever I have a medical or drug question Dr. Kolnik is always well-read citing studies to support his opinion or diagnosis.When I was having GERD issues, he ordered a MRI. Turned out that he found a cyst in my pancreas. Dr. Kolnik immediately recommended that I see a specialist.Subsequently, I had Whipple surgery and they found that the cyst was pre-cancer. His quick diagnosis saved me from pancreatic cancer and may have saved my life.If you want to see a down to earth doc that is well read and cares, look no further.

After seeing another specialist for 7 years, Dr Kolnick was able to find, diagnose and treat my recurrent issues. He is a lifesaver, in my opinion. I can now go out and socialize without worry.
