Mark S. Courey, MD
Professor and Chief of Laryngology, Director of the Grabscheid Voice and Swallowing Center of Mount Sinai

As the first otolaryngologist in the United States to complete formal fellowship training in Laryngology, Dr. Courey has focused his practice on the management of patients with voice and swallowing difficulties since 1992. A pioneer in the interdisciplinary approach for patients, Dr. Courey is recognized nationally and internationally for his leadership in the Laryngology subspecialty. He collaborates with patients, speech-language pathologists, voice scientists and other physicians to determine the optimal treatment solution for each patient. Dr. Courey has been instrumental in training more than 50 national and international laryngologists, and has cared for numerous classically trained and commercial vocal performers. He has extensive experience in voice science and the requirements of professional and performance voice. At the Belmont School of Music, Dr. Courey taught Anatomy and Physiology of Voice to vocal performance majors and graduate students in voice pedagogy. While at Vanderbilt, he directed the Vanderbilt Voice Center and served as the physician to the Nashville Opera and the San Francisco Opera. In addition to pioneering and promoting modern techniques of endoscopic laryngeal microsurgery, Dr. Courey has developed novel larynx-sparing techniques for patients with laryngeal chondrosarcoma. More recently, Dr. Courey has advanced voice care for transgender people, combining voice therapy with pitch-elevation surgeries (Wendler glottoplasty). This approach produces reliable outcomes and improves patient satisfaction in aligning voice with gender more rapidly and with greater stamina than previous approaches. Dr. Courey continues to promote the interdisciplinary team approach for patients in an effort to help patients avoid surgery whenever possible.
