I highly recommend Dr. Onishi. He listens, offers thoughtful suggestions, carefully lays out all the alternatives. He takes the time to see things from the patient's perspective. He's the kind of doctor you're looking for. The Show moreoffice is a bit of a whirlwind. Getting to the various machines is a little like jockeying for position at the DMV - though the folks that run you through the maneuvers are very helpful.

Dr. Onishi is young, well educated and an excellent diagnostician as well as kind human. The combo is rare in today's medicine. Can't recommend him more highly.

Patient, knowledgeable, congenial!

He was thorough and took his time to explain everything very well

Dr. Onishi was gray. The nurses at the front desk however need to get onboard. I left feeling very uneasy that everything prescribed, has to be waited on to start or try. The gentleman running the glasses/contact kiosk is seldom Available & his stock is always low for Contacts. There are a lot of bodies in that office but efficiency is not apart of that
