Dr.Buffer and his staff are the best!!! I struck gold when I chose Dr.Buffer as my cardiologist. I always feel better after seeing him. He has such a calm/soothing demeanor and so easy to talk with. Friendly/kind staff. Kudos to all! Cheryl is always so sweet and always gets back to me in such a timely manner. Incredible practice!
