I joined Dr. DeCarli's practice several years ago, he has such a wonderful style, that I am afraid it has spoiled me. But, thinking I would have him until my death, as fate would have it, it is not to be...I was very upset at the letter I received from him and thought he would have told me during my last visit to allow me ample time to find another Doctor. But, as you know...when you are on medicare, Doctors can't afford to accept too many write-off accounts.  So, I continue to seach for the right Physician. 
And, his office staff reflected his style also: just wonderful....goodbye to Dr. DeCarli

Overall Rating: 5.0 2019-05-11

Excellent doctor...sorry he is retiring...best I every had in 60 years!
