About William Reisacher, MD

William Reisacher, MD is a board-certified otolaryngologist, specializing in the diagnosis and treatment of airborne and food allergies in children and adults. He sees people with a wide range of general ear, nose, throat and allergy problems. His clinical expertise lies in the diagnosis and management of airborne and food allergies in adults and children.

As an experienced specialist in Otolaryngology, he is able to offer his patients the most effective balance of surgical and medical treatments for sinus and nasal problems to help them regain their quality of life and return as quickly as possible to the activities they enjoy. He treats patients of all ages and believes that taking time to listen to his patients and helping them understand all of their treatment options are necessary steps towards developing a trusting and effective doctor-patient relationship.Dr. Reisacher graduated from The Mount Sinai School of Medicine in 1994, with Distinction in Research, and completed his Otolaryngology residency at The New York Eye & Ear Infirmary in 2000.
