    He was my primary care provider. He's a very busy man and he's been wonderful. You know, he goes through everything. He does his records and I don't know how he keeps it all straight, but he does. He's a wonderful guy and he's been helpful. He's been getting my references and stuff. So I have no complaints about the guy whatsoever. Thank you.
