Doctor of Audiology
After growing up at the beach in sunny Southern California, John left to study in the redwoods at Humboldt State University where he received his Bachelor's in Education. He eventually moved to San Francisco to earn his Masters of Science in Audiology. His Doctorate in Audiology was obtained from Salus University in Pennsylvania.
Dr. Miles has been a practicing audiologist since 1980 and went into private practice in the late 1980's. He says, "The science of hearing and hearing aid technology is fascinating, but my biggest reward of being at work is getting to know my patients through their stories. I have learned so much from them."
He loves anything that has to do with the outdoors, including: camping, hiking, kayaking, skiing, and biking. He enjoys reading non-fiction books and has a particularly keen interest in orcas, otters, and hummingbirds.

"I have been a patient of Dr. John Miles at HearWell Audiology for almost a year. From the beginning I found his facility clean, his staff helpful and professional, and everyone seems to enjoy working at HearWell. My hearing has been terrible since I left the military in 1973. I was told there was no technology to help noise induced hearing loss and the best I could to do was take a class in lip reading.
After Dr. Miles put me through a series of tests he gave me a number of options regarding hearing aids. I was very excited get my first pair. From that day I have been amazed at what I can hear. I never heard my flip flops slap my heel as I walked! Dr. Miles has been very attentive to my questions and always has answers that I can understand. It is great to find a business that does what they say and say what they mean." - Rick
"What a pleasure it is to converse with others now without straining to hear especially at mealtime! Thanks for your kind service." - Marcy
"I feel like I am lost without my aids. They have helped me keep functioning in my daily activities. I appreciate the service that I get, and like that I can be seen by my audiologist when I need it. She helps me keep my aids working well. I’ve been seeing her for over 20 years and I wouldn’t go anywhere else. She is the best!" - George
