Reviews From Our Satisfied Patients

    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!

    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!

    Jacqueline P.

    Dr. Jade Himmelsbach was extremely professional and thorough in the examination combined with a warm personal manner. Support staff was very helpful. Highly recommend this practice.
