Excellent experience all round
I have been going to Dr. Clark for a long time and am very satisfied with his care.
great experience
He was great. I have high expectations of doctors, as I work with A LOT. He exceeded my expectations. He is great and I hope to be with him for a long time.
My provider always takes the time to explain things, and if I have a question or concern, he will always try to look it up and go over the information with me.
