You know you have a tight group of business leaders, when at least 100 persons show up for your June 20 networking reception at a MacArthur Boulevard dentist’s office in 100-degree weather. Georgetown Business Association members and guests met at the office and patio of Georgetown Smile, greeted by the likeable and professional Avraham “A.J.” Peretz, D.D.S., and his staff. Cold water, wine and soda along with sandwich wraps and pasta salad proved perfect at the end of a hot day. Maybe even better, there was a massage therapist — Janelle Jimason of Eastern Holistic Arts — administering soothing massages in the office’s receptionist space. Georgetown Smile t-shirts were handed out as well as samples from Sonicare and Colgate. One of the raffle winners of the Philips Sonicare toothbrushes was GBA secretary Beth Webster. (Plus: a quick thank you to GBA event chair Sue Hamilton for her headline quote.)
