When I was four, my mother brought my brothers and me from a poor rural village in the Dominican Republic to the Dorchester neighborhood of Boston. I knew no English. “We have to win,” she told us. She said, “So we have a donkey. Now we have to find a saddle and go somewhere.” I graduated from Dartmouth Medical School on a full scholarship. I bought a primary care practice here. Two weeks after I advertised on Spanish language radio, people were standing in the waiting room. I don’t tell my patients anything my grandmother would not understand. Today I oversee six clinics. I learned pain management at the Harvard hospitals. I’m part of Boston medicine. It’s a club. — Roberto Feliz, MD
