Internal Medicine

Dr. Hertzel Sure

Book a visit with Dr. Sure


“Internists are sometimes referred to as the “doctor’s doctor,“ because they are often called upon to act as consultants to other physicians to help solve puzzling diagnostic problems. General internists are equipped to handle the broad and comprehensive spectrum of illnesses that affect adults, and are recognized as experts in diagnosis, in treatment of chronic illness, and in health promotion and disease prevention—they are not limited to one type of medical problem or organ system. They are specially trained to solve puzzling diagnostic problems and can handle severe chronic illnesses and situations where several different illnesses may strike at the same time.“

Dr. Hertzel K. Sure is a board certified internist, whose personal history and professional philosophy make him an excellent doctor to work with.

Dr. Sure has affiliations with North Shore University Hospital of Manhasset, Elmhurst Hospital, North Shore Forest Hill, Mount Sinai Hospital, Fairview Nursing Home and Long Island Care Center. Dr. Sure opened his private practice in Elmhurst in 2003. 

Dr. Sure believes that in order to overcome a disease it takes more than medicine: the relationship between patient and doctor must provide a solid foundation for healing. His motto, which he applies in his practice, is this: the patient comes first, no matter what.
