Stumbled in for an eye exam and they were able to accommodate me the same day. I didn't have my insurance card but they were able to lok up my VSP benefits and save me a bunch of money. I love working with Gina and Lorelei and Dr. Montgomery. They are a great team!

We’ve been with Dr. Montgomery for about 2 years now. She’s amazing and is incredibly skilled in managing our family’s vision. We hope to stay with her as our provider for as long as she’s available.

Modern technology and really attentive staff. The doctors were very thorough and made great recommendations to help my dry eye and allergies with their eye spa wellness packages. The optical has a large selection of unique frames like Chrome Hearts and Cartier which I love. Happy patient who will be back every year
