Our services include comprehensive hearing exams, safe ear wax cleanings, hearing aid consultations, custom fittings, and ongoing follow-up care tailored to each patient’s needs.

Meet Our Audiologists
Our mission at HearQuest Audiology is simple: to bring expert hearing and balance care to those who need it most. From veterans navigating disability evaluations to seniors in rural communities, we believe everyone deserves a life of clear sound and steady footing.
Our practice is led by Dr. Reginald Arevalo, a Doctor of Audiology whose expertise in medical disability examinations has made him a trusted partner for the VA and SSI across Northern and Southern California. Dr. Arevalo’s passion for service is best seen in our Hearing Onsite initiative, where he and his team provide mobile audiology and hearing healthcare to neglected populations in Riverside County’s Coachella Valley and Bakersfield in Kern county who otherwise lack access to essential hearing healthcare.
With a clinical background from SDSU and UC San Diego, and years of experience at top-tier institutions like the Pacific Neuroscience Institute, Dr. Arevalo brings "big city" expertise to the communities that need it most. Whether he is treating a patient in a clinic or a care facility, his fluency in English, French, and Tagalog helps him connect deeply with the diverse communities he serves.
