Our provider is excellent and goes above and beyond the call of duty each and every time we see him. It is an honor to have him as our child's doctor.

January 06, 2017

Both my daughter and son had their appointments the same day with Dr. Kietz. In my opinion he is probably the best doctor we have ever seen, and we see a lot due to both kids on going health problems. He is compassionate, listens very well, talks to the kids and listens about personal matters, remembers everything from prior visits, and makes you feel all over comfortable. Never seems bothered like some doctor's and always takes his time. The kids absolutely say he is a great doctor.

Dr. Keitz is an amazing rheumatologist who has always spent a great deal of time talking to my son about his Lupus. He always talks to my son for his perspective on issues, and always answers his questions. He is the most amazing doctor we have ever had the pleasure of dealing with. He is caring, kind, and compassionate, and has done wonders in keeping my son's Lupus under control.
