Very efficient office. I was expecting a long wait and I did not even have time to finish the paperwork before they called my name (after getting there over 15 mins early). Very professional staff. Dr. Greiner was very kind and professional.

Second time I've been there. My first Doctor was awesome, but unfortunately, she retired. Second time comming in was not greeted lady ask for name and last name. She did apologies for me having to fill out the form again. Dr. Was good 10 min or less. My only only problem was the lady at the front desk . The lady who was makeing my next appointment was talkative, nice and friendly as I was leaving the lady who checked me in tells her man you friendly and talkative to everyone. That annoyed me. My issue is the young girl at the front desk.
