 I have been seeing Dr. Baker since he got out of med school, and he just keeps getting better!  His entire staff is great, rarely is there along wait, usually in in less than 15 min. If you are sick and need to see someone, they can usually get you in to at least see his PA within a day or two if not the same day. The care is excellent , if he feels you need to see a specialist, no problem, but he is more than capable to handle most problems. He and his office follow up, I have had him call my home at 7:30 at night to give me test results! He always listens and answers all my questions, I have found him to be very compassionate and caring.
