Dr. Karen Hsueh is THE best optometrist in town and her whole staff is patient and kind. I've been coming here since 2009 and they still offer the same great service. I would have to agree with the other people that the staff doesn't rush you so you can make the best decision possible. I also like how they offer name brand frames such as Gucci, Armani, Dior for those that want something hip and trendy. Another plus is that they take most insurances including CIGNA for Caesars and MGM Corp. I did walk-ins the few times I've been there but definitely make an appointment just to make sure you won't end up making a trip for nothing.
