I can't say enough about how awesome Dr. Zanger is - I have been his patient since [Date] 018 because of kidney stones. I am grateful to God and Dr. Zanger that I have not formed any stones since being in his care. A very kind and caring man!

My wife and I were very pleased with our first visit with Dr. Zanger. (Although we do know him since he has taken care of our daughter for years). He is so very knowledgeable and explains clearly. We respect him and trust him very much.
