Best place to go and best doctors.
This was a follow up appointment after a hospital stay where I was being followed by this care provider. Everything was explained to me in a way that I could understand, and Dr. ANDREW ALLEGRETTI is a very thorough and pleasant doctor to interact with.
Woman at front never acknowledged my presence when I tried to check it. She finally mumbled something from behind her computer screen but never made eye contact during the interaction. She remained hidden behind computer screen. She was not there when I tried to check out and after waiting a few minutes, I left.
