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.

He is phenomenal. However I left because he is a part of GANJ with whom I had a horrible experience With two of his colleagues as did my mother before me. Too bad he does not go on his own. I would go back to him in a heart beat. His nurses are wonderful too.

Dr. Kosc is one of the friendliest doctors I have ever visited. His staff is super-nice, too. Dr. Kosc helped me with my acid reflux problems - and they are now under control. He spends the appropriate amount of time with his patients and explains everything in an understandable manner. He is also willing to answer any questions about your condition. I feel very confident in his care.

Dr. Kosc was recommended by a family member who's life he saved when no other doctors could figure out her problem. Turned out to be a blocked bile duct. I've been seeing Dr. Kosc for over a year and he is wonderful. Knows his stuff. Takes time to consult with you. Doesn't rush you out the door. If you have an emergency the ladies in the office get you in for an appointment as soon as they can. Highly recommend Dr. Kosc if you need a Gastro. A genuinely nice man who is compassionate! Go see him!
