Dr. Leigh Mast

Dr. Mast has experience in presbyopic, astigmatic, keratoconic, and post-surgical contact lens fitting and is also certified in orthokeratology.

Dr. Mast moved to Washington and completed a residency in primary care and geriatrics at the American Lake VA Medical Center in Lakewood. While working at the VA, she provided primary care including the diagnosis, treatment, and management of ocular disease, and low vision rehabilitation.
