Dr. is very easy to talk with about medical aspects of the treatment given at NM. He listens to what I say, and even laughs at some things that I think are funny. He is a very likeable person, and I am glad he is taking care of me. Our daughter is a pediatrics anaesthesiologist, and they have the same personalities. Will listen, then be very direct in solving the medical problems. Much appreciated.

External Professional Relationships

Pharmaceutical, device, and biotechnology companies frequently collaborate with basic scientists and physicians within an academic medical center to help advance science and improve patient care.
