Great doctor!
June 22, 2024Barbara P.Verified patient
I was happy that the doctors office called prior to my appointment to confirm what I was being seen for. Once they understood, they made an effort to reschedule for a more appropriate time so that I wouldn't have to wait long once I got to the office. When called in, the process was efficient. They asked a bunch of questions about my issue and history, immediately brought me in for x rays and the consultation followed immediately after. It was a pretty good experience.
