My son was bitten in the eye by a dog in 2007. Dr. Koo saw my son right away (we had to wait, of course, because he has a very busy practice, but my son was seen the *same day* I called) and treated him immediately, so he wouldn't have to wait to get the prescription to have some pain relief. He was also very thorough in explaining what had happened, why he was doing what he was doing, what to expect, and after the initial healing time, he had us schedule a couple of follow-up appointments to make certain everything was 100%. Dr. Koo has an incredible bedside manner, and I have complete confidence in him. And that's saying something, because usually I'm skeptical about doctors' abilities. Dr. Koo knows his stuff and obviously cares deeply about his patients and their families. I also found the staff helpful and pleasant. I've recommended Dr. Koo to many of my friends, family, and colleagues and they have all agreed with my assessment of Dr. Koo. We always joke how lucky we are to have such a great eye doctor "on call." I couldn't give a higher recommendation to him.
