An expert in rhinology & minimally invasive skull base surgery, Dr. Jonathan Overdevest focuses on therapies and procedures that restore sinonasal function. He specializes in managing the care of patients suffering from symptoms of chronic rhinosinusitis, nasal obstruction, chronic nose bleeds, sinonasal and intracranial skull base tumors, as well as eye issues such as excessive tearing. Dr. Overdevest completed his rhinology and skull base fellowship training at Stanford University, and his Otolaryngology – Head & Neck Surgery residency at UCSF (University of California, San Francisco). While training, he was recognized for his “exceptional warmth, compassion, and service to patients,” with numerous awards, including a coveted AOA Outstanding Resident Award, the Julius R. Krevans Award for Clinical Excellence, recognition as an exquisite provider as the Surgical Consultant of the Year, and was named a UCSF Medical Center Outstanding Physician Award finalist. Before his medical training at UCSF, he graduated from the University of Virginia, where he received both his MD, as well as a PhD for my doctoral research where the team identified and subsequently developed an immunologic therapy to target a key molecule involved in the metastatic migration of tumor cells. His undergraduate training was completed at Cornell University, where he was a Cornell Tradition & Francis S. Viele Fellow prior to graduating cum laude and with distinction. Dr. Overdevest believes in a multi-disciplinary approach to patient care, and regularly participates in collaborative management of patients with various Ophthalmology, Plastic Surgery, Allergy, and Pulmonology colleagues. In particular, he works in close collaboration with our neurosurgical team to assist with the removal of brain tumors that are accessible through a minimally invasive corridor created through the nasal cavity. Our practice at Columbia seeks to provide a compassionate and comprehensive setting for patients with sinonasal complaints. As a team, we will reduce the severity of your daily symptoms and work to improve your ability to overcome the underlying cause of your sinonasal disorder. When not engaged in his medical practice, he lives with his family, a stone’s throw away from the American Museum of Natural History, where they regularly go whale watching. He is avid alpine skier who tries to keep up with his 70-year-old in-laws, as well as an endurance cyclist looking to soak in the spectacles of all seven continents.
