[staff] was a highly skilled Navy physician; Dr. Anthony Keller, a Navy-trained flight surgeon, would be an excellent choice to follow up with, as both share a practical and straightforward approach to patient care. It's advantageous that he started his medical career in Internal Medicine; I hope he will consider my request to be my primary care physician, as I require his dual certification.Dr. Keller would be an ideal primary care physician for me.
