Dennis is a great optician and the store's selection and pricing is great.
The store packs tremendous selection into a smaller store and he is happy to either direct you to a style and brand or let you choose your own. I have bought 4 frames from him and recommend him to tons of friends. Pricing is competitive and the product assortment is great - he skims the highest quality frames from brands you know and some that you may not know.
More important is that after-sales service is also great. For as long as Dennis is selling glasses he can count on me as a customer.
