Audiology Specialists


Dr. Valerie Guzzo

Pediatric Audiologist, Lead Cochlear Implant Audiologist

Doctor of Audiology, Northwestern University, 2012

Began working with cochlear implants while in undergraduate school at University of Illinois Champaign Urbana while volunteering at Carle Hospital’s Cochlear Implant Clinic for two years. Immediately began focusing on cochlear implants upon entering Graduate school at Northwestern University and spent my externship year at a Moog Oral School for the Deaf learning to combine clinical audiology, pediatric audiology and educational audiology into one specialty. After graduation I continued to spend time working at Northwestern University and the adult cochlear implant institute until moving to southern California to pursue a specialty in vestibular diagnostics and rehabilitation with an emphasis in pediatric audiology. I spent 5 years as the director of pediatric audiology, amplification, and education and training and a private practice in Newport Beach California until the lead position at Providence opened up and I am now able to combine my passions of implants, pediatrics, vestibular audiology, and working in a collaborative and passionate team environment to help serve the community every day.
