Dr was friendly, knowledgable, professional and easy to talk to. Made me feel very comfortable. Classic rock playing when I was wheeled in; I complimented Dr. on his taste in music and he even offered to change it .. I asked about a little Bruce and he changed it. Wow! Great staff as well.

I seen Dr Zierer as a new patient. He was listening to me and taking note of my overall health as he examined me. He took the time to educate me as well. He is very knowledgeable and focused (even through my rambling) and I feel at ease that I am in good hands. His office staff where very efficient, friendly, professional and smiling. It was a refreshing environment to be in and will recommend them to anyone I know.

1 week after testing, 5 phone calls and 4 emails, via patient portal, and still no response from the doctor regarding the results of my test. I would not recommend this doctor to my worst enemy. Stay away!

This Dr. was the first to be brave enough to diagnose me with a rare condition in men (Rheumatiod Arthritis) he treated me during a very difficult financial time and managed to make it be very stress free and affordable for very expensive medications.
