Ok so where should i start! Its local in Plano! Excellent customer service provided by their entire staff! Specially Richard is absolutely amazing! Very patient i had a million questions regarding coverage and cost and he patiently answered all of them. Doctor is very nice does not make you feel rushed gives you time needed and answers all your questions and concerns. Very good selection of glasses. Kid friendly. The office has  very vibrant and positive energy.They are very comparable in terms of pricing to other local vendors and warehouses. Highly Recommend this office!
