Dr. Alex Tan and his staff are the epitome of what it means to be knowledgeable, caring and fun wrapped into one. This practice is exactly what I'd been searching for while looking for an optometrist for myself and my husband, and they've only exceeded expectations at every turn. Dr. Tan provides every option for glasses, contacts and eye care and follows up in ways that you couldn't imagine another doctor doing. His support staff are also on point; from Mark's kind ability to help find and fit frames that work on your face to the desk staff working with your financial needs. If you are in the Oak Park area, this needs to be your practice, hands-down.
