Biography & Education


"To me, the practice of medicine is a partnership and dialogue - between patient and practitioner. It is my privilege to serve as a guide for my patients through the sometimes difficult maze of signs, symptoms, diagnostic tests as well as evolving technology and medications. I strongly believe in a holistic approach to medical care and approach each patient I see in this manner."

Dr. Eisen received his medical degree from Albert Einstein College of Medicine in the Bronx, New York.  He later completed his internship and residency in internal medicine at Mount Sinai Medical Center in New York City where he became Chief Resident.
