Dr. Leibner's Office
Dr. Leibner has created an office based on a simple, if not old-school, philosophy of individualized care. We believe that the best medical care is achieved by: 1) truly listening to the patient; 2) taking a thorough history of the problem; and 3) conducting a physical exam and testing (e.g. allergy testing, pulmonary function testing, and/or laboratory evaluation) as each individual case may require.
No mills, no giant clinics, no seeing different doctors every time you visit, and no physician substitutes - just the doctor and patient working together for the best results. Our office staff takes great pride in providing courteous, friendly service to each of our patients. By treating patients in the same manner that we would like to be treated ourselves, we believe that our patients are truly pleased with the care they receive.
Since 2000, Dr Leibner has been named to the “Best Doctors in the New York Metropolitan Region” by the prestigious Castle-Connelly publications. New York Magazine also named him one of the New York Metropolitan Area’s “Top Doctors”, and he has been named to the “Best Doctors” list by Inside New Jersey Magazine, a publication of the Star-Ledger.
