In the three years I've been seeing (no pun intended) Dr Poon he's been extremely helpful in dealing with my significantly-more-complicated-than-average contact lens situation.
He uses his expertise in a thorough and conscientious manner to obtain the best results. He's also good at communicating and explaining.
On the two occasions when I've called to ask to see him that day because of something unexpected having occurred, he's made time to see me and has been able to deal with the situations quickly and effectively.
Though I don't wear glasses, from everything I've seen and heard in the outer office area while waiting, it appears this is also a place where people are having a comfortable and satisfying experience getting glasses.
