Roy Koga should not be a doctor.. Spends all his time on his computer.. He really does try to fake or lie about labwork.. Very dangerous.. Defiantly needs to be out of practice from the medical field..

I have been with Dr. Koga for over 7 years, he has provided me with great services. He is old school Dr. tells it like it is and gets the testing needed for your health. I get most of my treatment with him and the VA but I have great services from him and his staff. He has follow ups, sits and talks about your concerns, even explains what is the issues diagnosed with a printout of the problems, I like him and his staff. Straight to the point Doctor no sugar coating.

Worst doctor ever. Spends all his time on computer. Can't remember the reason for appointment. Doesn't remember human anatomy. Appears to suffer some form of dementia. Gives false interpretation of lab reports or pretends to have labs when he can't find them. This guy is dangerous. If you want to live, find another doctor!

Very insensitive to concerns. Doesn't explain treatments. Uses foul language.
