Dr. Robert S. Feferman

DocDr. Feferman specializes in the treatment of hormone imbalances, menopause, pituitary disease, osteoporosis, and thyroid diseases. He utilizes bio-identical hormones, the exact hormones the patient used to make, to regulate hormone levels for women as well as men. Dr. Feferman uses extensive blood work to measure baseline hormone levels. His services, as well as the laboratory charges, are almost always covered by health insurance. Other services include the treatment of pituitary and adrenal disorders and weight management. He offers the latest state-of-the art equipment to determine the risk for osteoporosis.
