Dr. Matthew Enos, O.D.

Dr. Enos grew up around Optometry and he was inspired to become an Optometrist by his dad who has been in the business as an optician for 40 years! Dr. Enos was the first in his family to attend college. He received his undergraduate degree in psychology from Cal. Go Bears! Dr. Enos earned his doctorate of Optometry in NYC at SUNY College of Optometry where soon after his brother followed in his footsteps and also became an optometrist! Dr. Enos returned to the Bay Area for residency training where he had the pleasure of caring for our nation’s veterans at the SF VA Hospital. It was here he received extensive training with UCSF faculty on managing glaucoma, macular degeneration, diabetic eye disease, and various other ocular diseases. He completed his training in 2014 after which he spent 5 years living and practicing in San Francisco where he built up a great reputation for exceptional optometric care. His patients over the years have attested to this in several online reviews and in 2018 he was voted “Best Optometrist in SF,” by SF Examiner’s annual people’s choice awards. This past summer he, his wife, and their newborn son decided to make a permanent move back to East Bay, and we are excited to have him as a  permanent addition to the team here at Orinda Optometry Group. Dr Enos prides himself in providing thorough and high-tech eye care with an emphasis on patient education so you can fully understand your eye health. Dr. Enos is currently serving as the president-elect of the Bay Area Optometric Council.
