Our Story

Audiology Services of Marin was founded in 1980 by experienced audiologist Dr. Lisa Dundas. From the very beginning, we’ve been committed to providing exceptional audiology services to our patients living in Greenbrae, CA, and surrounding areas of Marin County. We’ve maintained that commitment by staying current with hearing aid technology, providing hearing evaluations, and through our interactive treatment process. We have long-standing relationships with many physicians in the area who can speak to our level of professionalism and care.

We believe that the best treatment for hearing loss is a combination of thorough testing, technology, and ongoing consultation. We’re not satisfied with simply fitting you for hearing aids. In fact, that’s just the beginning of our services.
