Summary

Dr. Friedman is a world renowned leader in the treatment of acoustic neuromas. He began his career as a fellow at House Clinic and later joined the group as an Associate where he had a busy practice for 15 years. He now serves as Division Director of Otology, Neurotology and Skull Base Surgery in the department of Otolaryngology-Head and Neck Surgery at Keck Medicine of USC. He is an NIH funded scientist and his laboratory studies the genetics of common forms of hearing loss. Dr. Friedman belongs to a majority of the societies in his area of specialization, including the American Academy of Otolaryngology-Head and Neck Surgery, the American Otological Society, the Acoustic Neuroma Association, the American Neurotology Society, the North American Skull Base Society, the Triological Society and the NIH/National Institute of Deafness and other Communication Disorders (NIDCD) where he serves as an Ad Hoc Reviewer
