Doctor Sanfield is not only professional and knowledgeable he is a doctor who is also a real human being. He will take the time to explain your treatments, your issues and anything else you wish to discuss. I’ve never gotten the impression that he is impatient or ready to push me through to get to another patient and for a doctor he actually has really good handwriting! :-) I have been under his care for years and even though he isn’t in my «network» I feel it’s worth the extra cost to continue to see him. If you need an endocrinologist, there is no one else I’d rate any higher than Doctor Sanfield.
