I have been a patient of Dr. Drinnon’s for over 20 years. He is thorough, thoughtful and caring. He is what a doctor is supposed to be, and I’ve referred many of my friends to him. I trust him completely.

Dr. Drinnon IMHO is one of the best. Very dedicated and truly cares about his patients. I've been going to see him for more years than I can count. Wouldn't trade him for the world.

The one important aspect of this physician's practice is that he isn't afraid to read. In other words, he keeps up with medicine through continued training and review of medical journals. This is important when needing an Internal Medicine Physician to be up-to-date with new medical approaches to diseases and ailments. In addition, he spends the time needed to determine what may be the medical malady and develops a plan to address it.

We relocated to Chattanooga in 2007. I highly recommend Dr. Drinnon. He, as well as his staff, is caring and very professional. He is very thorough and you never feel rushed during his exam. He recently moved into a newly built office that is modern and clean. He has an onsite lab and xray. Really a wonderful doctor and individual.

I love, love, love Dr. Drinnon. He is very attentive to my needs as a patient. I was recently diagnosed with M. S. and because of Dr. Drinnon I was diagnosed fairly early and was able to start on my medication. He saw that my situation was getting worse and sent me for an M.R.I., he didn't just write me a prescription and send me out the door. Thank you Dr. Drinnon for taking care of me. And thanks to your staff for always fitting me in when I need an appointment and to Nurse Brenda for always being so caring.
