Going to any medical facility is always nerve wracking. But Dr. Zak walks in, warmly greets you, and you know everything will be ok. At least that was my experience.

Debra S. • March 06, 2025

Ivan W. • February 27, 2025

Tyrone B. • February 01, 2025

The visit with Dr. Kleinbart gave me a lot of confidence going forward that the heeling process of my knee would be smooth and effective.

Tyrone B. • January 31, 2025

I went in with a plantar’s wart that was causing a lot of pain in my foot and ankle when I walk. I hoped that there would be something more than lotion to continue put on it. Although, I was quickly told that there “isn’t much I can do” and that I will continue to be pained with these warts for the rest of my life, despite this being my only ever instance of a wart especially on my foot. I know the cause and chances of a possible return but I left with the impression that the wart won’t go away or continually come back and that lotion, a stone for removing dead skin, and prayers are the only solution to this wart.

Andrew D. • January 29, 2025

Marc L. • December 26, 2024

Dr Kleinbart is wonderful - he is professional, caring, and explains everything very clearly and thoroughly. I am delighted with the results of the surgery he performed.

Barbara S. • December 17, 2024

He answered my questions and gave me encouragement.

Ellen M. • December 08, 2024

This was a necessary followup doctor visit after a trip to the ER. The staff worked with me to schedule an appointment the same day. Dr. Zak was efficient, knowledgeable and explained things in a way that I could understand. The walking boot he provided is much more comfortable and workable than the splint the ER put on. I feel confident in the care he provided and would recommend him.

Joanne W. • November 19, 2024
