I can't say enough good for Marc and his staff. He really took the time to listen to me and help figure out my health issue.

April 24, 2017

The visit was great, staff and doctor were attentive to my questions. I was disappointed in the tardiness of the doctor, as my 8:30 appointment started at 9, when no one else was in the waiting room and I was likely the first or second appointment of the day. The nurse got my vitals by 8:27, but the doctor did not arrive until 9 to see me.

I always receive excellent care from Dr. Schwartz and his office. Although I wasn't seen within 15 minutes of my appointment time, I was told when I checked in he was running behind. He always spends time with you and addresses all your concerns.
