Dr G is not only very nice but he takes the time to explain everything to you in a way that someone who doesn’t have a medical degree can understand. He ask you if you have any questions and he answers everything to where you can understand it without having to follow up with a second question. His facility is very nice and clean as well is his staff. Dr G. and his steadfast make you feel very comfortable and that don’t rush you at all. As soon as you walk in the door everyone there makes you feel comfortable and they offer to help you with any need that you might have. Their facility is very conveniently located right off of the highway and there is plenty of handicap parking right in front of the front door. I will definitely be using Dr G as my new Nephrologist.

Dr G is my hero! He asked all the right questions and had figured out my problem during the initial visit. Ordered tests to confirm. I am finally feeling so much better after suffering for a year. I can’t say enough good words! Knowledgeable, great listener, thorough, kind, caring. And his staff is a reflection of those characteristics.

My husband and I so appreciate the time that Dr. G. spent with me in order to try to find out my problem. I have tried to convince doctors for over 15 years that something was wrong, but none would listen. Dr. G. took that time to listen, figure out the problem and I am 110% better today. Dr. G. is a genuine caring doctor, very intelligent in his field and very professional. I am so thankful for Dr. G!
