Welcome. The purpose of this letter is to acquaint you with my background, training and philosophy of medicine.

I was born in 1954 and grew up outside of New York City. Originally, I trained to be a mechanical engineer at Cornell University and at the Massachusetts Institute of Technology, where I received my Bachelor of Science and Master of Science, respectively. I attended medical school at the State University of New York in Syracuse, NY. After 4 years of medical school, I completed a 3 year training program in Internal Medicine at Vanderbilt University School of Medicine in Nashville, TN and two years of subspecialty training in the field of endocrinology at Massachusetts General Hospital.

I am Board Certified, by the American Board of Internal Medicine, in Internal Medicine and in the Subspecialty of Endocrinology and Metabolism. In 1992 I was elected to become a Fellow of the American College of Physicians. Internal Medicine, sometimes known as "adult medicine," is a branch of the medical profession which encompasses most adult diseases, including diseases of the heart, lungs, stomach, liver, kidneys, nervous system, joints and blood as well as the management of infections and critically ill patients. When a medical problem is unusually complicated, I will refer my patients to a physician who is a subspecialist. A subspecialist is a physician who has had advanced training in a particular disease or organ.

My subspecialty is endocrinology. Endocrinology is the branch of Internal Medicine which treats diseases of the pituitary gland, thyroid gland, parathyroid glands, pancreas, adrenal glands, ovaries and testes. Some common endocrine diseases are diabetes, "a goiter", thyroid problems, infertility, irregular periods, thin bones, high cholesterol, adrenal gland problems, women who have excessive hair, pituitary tumors, abnormal breast discharge, thyroid nodules, thyroid cancer, high calcium levels and high blood pressure.

We believe it is our role to inform you how to promote good health. In order to accomplish this, we may prescribe medicines, order laboratory tests or recommend that you alter your life style. However, you must make the final decisions regarding all health matters. It is our hope that you will base your decisions on information you receive from us, other health care professionals, books, magazines, your family and friends and meld these opinions with your own personal "philosophy of life" in order to decide the best therapy for you.

Please complete the enclosed medical questionaire and bring it with you to your appointment. Your first appointment will take between 20 and 60 minutes. If you are unable to keep your appointment, please cancel at least 24 hour in advance. We look forward to seeing you.
