Dr. Greenstein was born in New York. He attended college and medical school at the University of Pennsylvania, where he graduated with top honors. He came to Boston in 1991 to do his internship at Massachusetts General Hospital and his residency at Boston University and Tufts University. After completing his training in 1995, he joined Northeast Dermatology and has been here ever since.
Dr. Greenstein specializes in medical and surgical dermatology. He also does allergy testing, hyperhidrosis treatments and some cosmetic procedures. Dr. Greenstein has also run our clinical trials unit for the past 15+ years. During that time, he has supervised over 50 clinical trials in acne, psoriasis, rosacea, eczema, actinic keratosis, skin cancer and various cosmetic treatments. These trials have led to the approval of many of the exciting new treatments in dermatology today. Dr. Greenstein also has an interest in teaching and has been the director of dermatology for Beverly Hospital’s family practice residency program (now defunct). He currently precepts Tufts PA students for their dermatology training. He also has an interest in teledermatology and other “cutting edge” technologies.
