Dr. Posey recognized symptoms of endocarditis within seconds on my first visit. Previous doctors had spent a year and run $10,000 worth of tests and learned nothing. I would have died without his medical genius and I tell that to as many people as I, appropriately, can.
I have nothing but praise for Dr. Posey. If he had been my doctor when I first developed endocarditis, I would not have needed a heart valve replacement. May he live forever!

Dr. Posey takes the prize for the most caring physician. He spends time getting to know you as a person. Obviously he cares a lot about his patients. He should be the model for all physicians. I once had another OBGYN who never even looked me in the eye. I think she was counting the money she was making from her 2 minute visit with me so she could buy more gold and diamond jewelry, which she already wore so much of I don't know how she was even able to stand up!
