My appointment on 2/5/24 went very well. Everyone was very friendly, and helpful. My doctor spent time with me to go over all that was important to my visit. When I left I understood everything about my health, and what Dr. Zierer was going to do for me on my next appointment. I'm very sad to hear that he is going to be retiring soon, and I from the bottom of my heart wish him the very best retirement a good doctor deserves. Thank you all!!
