I would 100% recommend Dr. Guenthner and her team! Our daughter completed vision therapy here for strabismus. We were originally going to go the surgical route because that is all we knew. After doing research I learned about vision therapy and I am so happy we went with it. It has helped her eyes so much. It is not cheap but it is so worth it!

Good heavens - I was there forever asking questions and trying on frames. But never felt rushed and had knowledgeable doctors and staff help me until I knew what to do next and what options were best for me. Thanks, guys. Great job!
