My goal as the director of the USC Voice Center is to improve the quality of life for individuals with voice, swallowing and airway disorders. I strive to achieve this through a true interdisciplinary approach to promoting health, preventing and curing disease, advancing biomedical research and educating those around me.

I received my undergraduate degree in economics at the University of Virginia, but my passion is for medicine. I graduation medical school from the Johns Hopkins University and then pursued training in Otolaryngology – Head and Neck Surgery at the University of Michigan. While there, I did an NIH funded research year and became interested in voice, swallowing and airway disorders. This led me to pursue specialty fellowship training at the Vanderbilt Voice Center. I then founded the Emory Voice Center with Speech Pathologist Dr. Edie Hapner, PhD in Atlanta Georgia, which was amongst the first interdisciplinary voice centers in United States. 12 years later, I was recruited to the University of Southern California to form the USC Voice Center and bring our interdisciplinary model of care to Southern California.

I embrace a caring, patient-centered approach with my patients. At the USC Voice Center, my patients can count on a coordinated, cohesive and unique experience backed by a team of voice and swallowing experts to optimize outcomes and satisfaction.
