About Us



Our specialists are equipped to provide tests and  diagnoses, and to recommend effective treatments across a wide range of  hearing and balance disorders. Our national certifications and  specialties include both pediatric and adult diagnostics and care.

Our staff works as a tightly knit team to provide the best possible  care to your patients. Experienced audiologists and a professional  support staff build lasting relationships with both doctors and  patients; children are a special favorite.

It is not uncommon for us, after review and in the interests of  prudence and best practices, to call the referring doctor and recommend  the elimination of a redundant test or the substitution of a preferable  one, based on that patient’s symptoms.

about our phoenix audiology practice

Our History

Founded back in 1995, ABHA operated as the outpatient Balance and Hearing Center on the campus of St. Joseph’s Hospital and Medical Center. In January 2004, office expansion caused us to move just a short hop — right across the street from St. Joe’s.

Well established throughout the Greater Phoenix area and beyond, ABHA offers world class clinical services in hearing and balance (vestibular) testing, pediatrics, and neurodiagnostics.

We still enjoy a strong professional working relationship with St. Joseph’s and the Barrow Neurological Institute, as well as perhaps the majority of Neuro-Otologists, Oto-Neurologists, Otolaryngologists (Ear, nose and throat), Internal Medicine practitioners and Pediatricians in the area.

Dr. Marvin Lewis, Au.D Doctor of Audiology

Au. D. Doctor of Audiology, A.T. Still University, Arizona School of Health Sciences
2005

M.S. Masters in Audiology,
University of North Carolina, Chapel Hill
1991

B.A. Bachelors in Audio Engineering
Indiana University, Bloomington
1980

Dr. Marvin Lewis, Au.D., comes to us after having directed two different private practices in Ohio. He is licensed in Arizona, and a member of many professional organizations. He has been dispensing hearing aids for over 26 years, but started his professional life working with his first love, music. Recording musicians, bands, and feature news programs was fun, however, he decided he needed a change after 10 years.

The new field had to include sound, and Audiology was a perfect match. He uses his previous knowledge of electronics and acoustics and applies them to audiology. Now, on a daily basis, he is happy to be involved with people who have hearing issues, improving their hearing. Making it possible to enjoy music, conversation, animals, and the sounds of life is very rewarding to him. His approach is uniquely personal, more of a detailed chat, to understand the patients’ individual needs and educate them as to what options are available to them. The aim is to have a well cared for patient, and quite possibly a new friend.

He lives in Ahwatukee with his wife and dog.
