    Had my first appointment today. Staff were friendly and professional. The office space was very nicely laid out. Dr Anne Berk was thorough in her exam and explained everything as we went and recapped before I left. I highly recommend Happy Valley Vision Source for your optometric care.

    Dr Nancy Buset was fantastic with my sleep deprived 3 year old. She has been my husband's doctor for years and now has another grateful and lifelong patient. The other staff at the clinic were also wonderful and very helpful.

    I've been a patient since 2018 and I've only had great experiences with all the staff - everyone is just so great! There is a great selection of frames and that are VERY high quality and I've never had any issues! I love the texting feature to communicate and having access to my secure patient portal.
