Dr. Lassa Frank

Mt. Tam Optometric Center owner, Dr. Lassa Frank, proudly distinguishes his optometry practice as one of the most progressive in the eye care business. Located in San Anselmo, CA, Dr. Frank’s practice has become a well known one-stop shop for Marin County citizens needing vision care. With the use of cutting-edge technology and progressive treatments, customers are assured that they are receiving the best available service when contracting for eye care with Dr. Frank.

His services include: eye exams, prescriptions, contact lens fittings, pre- and post-opertaive cataract surgery care, as well as the diagnosis and treatment of a wide variety of eye diseases and injuries. He serves the very young to the elderly and is pleased to offer complimentary 1 year baby checks. This valuable service helps assure new parents that their children do not have noticeable problems that could lead to critical issues in the future. His customer base is derived mainly through “word of mouth” referrals from satisfied clients.

During Dr. Frank’s 20+ years practicing optometry in Marin, he has traveled extensively around the world and has personally given over 25,000 free eye care exams to the poor. He has put together eye care teams that have delivered over 100,000 pairs of glasses to the needy in Africa, Central America, and Mexico. He has worked with numerous non-profit organizations and is proud to be one of the founding members of what is now Lions in Sight, a charitable non profit group that provides eye exams and eyeglasses to those in need around the world.
