Dr. Steinberg is a top-notch allergy/immunology doctor. I first saw him in 1999 for my severe springtime allergic reactions. After having a complete allergic skin test, he tried to work with me to create a way to keep my allergic reactions to a minimum during the springtime. A year later I began immunotherapy (shots). Unfortunately after three years it became clear that I belonged to the small percentage that it did not benefit from it. I must say that Dr. Steinberg's knowledge is immense and he tries all he can to help his patients. He has been recognized by "Best of Boston" and he has traveled across the U.S.A. to speak at many allergy-related conferences and engagements. The only negative is that one of his staff members can be a bit unfriendly and abrasive at times.
