  • Administrative staff cited for being rude or difficult to communicate with

"From the front desk girls to the cna to Dr.Atassi's assistant to Dr. Atassi himself, I had an excellent experience at this practice. I only waited 5 minutes at the most, Dr. Atassi was very kind and explained everything so well."

— Birdeye review

"Administrative staff can be very rude. Since they are the "face" of the practice both on the phone and at location, I would suggest some in depth coaching of manners and understanding of geriatric needs."
