Dr. Lantzy has always looked after me since I have diabetes and high blood pressure. I had a diabetic dr. Before her and he never looked at my feet, and that is an important fact to do. I never go in Dr. Lantzy's office that my feet aren't checked by her. A lot of things are checked that other physicians don't do.

My provider has helped me since I started going her for diabetes. I go to her because she has gone out of her way to listen, care for me, and give me her attention to my health. I quit going to the provider I had before her because he never checked my feet in the year I saw him, only wrote on a pad. She is a very,very good doctor.
