Reviews From Our Satisfied Patients

    Great staff. Love the office. 

    A K

    I've been going here for years to get my eyes checked and staff is always very friendly, passionate, and professional. I love Dr. Anne Berk as my optometrist. She is very knowledgeable and passionate and caring with her patients. That is very hard to find in a doctor nowadays.

    My family loved the staff! They were super friendly, informative and they never rushed us. They had great choices of glasses frames and the newest options of contact lenses. I recommend them to any family.

    I loved Heather! She knows her job! Delightful personality! She picked a nice style of frame, suitable for my prescription! She made a few adjustments and all was good! Thank you so much!

    Linda N.

    I had the BEST experience at Happy Valley Vision Source! Every member of the staff was kind, knowledgeable, and went above and beyond to ensure I had a great appointment. Doctor Anne kept my 10-month-old completely happy with a bunny puppet during my exam, and even held her when she started fussing, while I chose new frames. The woman helping me with frames was amazing too! I've never had someone take so much time in helping me choose frames that looked and fit perfectly! Thank you all!

    Heather, the current Optician is wonderful. She is bubbly, knowledgeable, and not LAZY! She expends herself wholly for us, the patient. My hope is that she stays there for a long time!
