Dr. Katz spent a great deal of time with me. I never felt rushed. He genuinely cared about my health issues. I left knowing what my problem was and how it would be taken care of!

Dr Katz is a great Dr. I would recommend him any day, every day. He is so patient. Always has time for any questions or concerns that I have. Getting an appointment is never hard. I can always get in to see him within a day or two. A lot of times, I can get in the same day. Wonderful Dr.

I've been a patient of Dr. Katz's for eight years. He is extraordinarily skilled at what he does. He's patient, makes time for questions, and never leaves me feeling rushed. I think some who see his bedside manner as less than ideal need to spend a little time getting to know him. I'm convinced they would warm up to him. He is analytical, and I think that might come off poorly for those who first meet him. Dr. Katz is a first-rate doctor.

I saw him in the hospital, he was excellent at the bed side and was good at explaining things even though I was in rough shape.

i have two friends who go to this guy and they love him. i got a referral to him and waited 4 months to go see him. he had a horrible bedside manner and was very arrogant. i told him my hypothyroid symptoms, gave him my labs...and he told me i should do more aerobics, it works for his wife. i left there crying...my husband went back to talk to him (he was in the room with me during my appt) and in a politically correct way told him he treated me very poorly. i would not go back to this guy for ALL of the money in the world.

He's certainly opinionated and "doesn't believe in anything holistic," including bioidentical hormmones.Overall bad attitude and overbearing.
