Our Eye Doctors & Staff

The eye care professionals at Northwest Vision Center specialize in understanding how the human eye really works, as well as diseases and conditions that affect your vision – many of which do not have obvious symptoms. Eye doctors know how age and risk factors affect vision over time for young and old, and they understand the benefits and features of corrective lenses including eyeglasses and contacts.

Our optometrists take the time to explain the results of your eye exam, describe your options and listen to your eye care needs. Because maintaining good eye health is an ongoing partnership, we encourage you to ask questions and share your health information, which could be vital to monitoring, diagnosing and treating potential vision problems.

Prior to coming to Northwest Vision Center in April of 1996, Linda was a manager for DOC Optical where she learned many of the skills that serve her well today. Being the first licensed optician hired at Northwest Vision Center in the early stages of the practice, Linda was instrumental in growing the practice into the thriving entity it is today. Deciding that family life was becoming a priority, Linda became a part-time employee, gradually leaving entirely to stay home and raise her children. Once her children were in pre-school, Linda decided that it was time to begin working part-time again, gradually increasing her hours as her children became more independent. She returned to Northwest Vision Center full-time in the spring of 2012.

Linda is the main frame buyer for Northwest Vision Center. She is especially interested in funky, trendy, unique frame lines, as well as classic styles. Linda has lost count of how many pairs of glasses she owns. Between regular and sunglasses, she estimates the number to be in the 20-25 range!
