Reviews From Our Satisfied Patients

  • "We use Anderson Optometry for all of our family’s vision needs. Recently, we had to have our youngest fitted for new glasses and he made the experience fun for her and informative for us. We know Dr. Anderson will always take good care of our family’s eye care and that’s why we wouldn’t go to anywhere else."
    The Harrison Family
  • "Dr. Anderson and his staff are so patient and friendly. Dr. Anderson prescribed me glasses and I had the toughest time picking out frames. They didn’t rush, but instead made helpful suggestions and now I have an awesome pair of frames, not to mention the fact that I can see ten times better than before. You guys are the best!"
