Excellent, caring assessment and follow-up to my sleep study, by Nurse Practitioner Aiko Loo and staff, who helped me into wheelchair outside and into office—very thoughtful and proactive with disabled patients. Much appreciated.

It was very difficult to get in the building, and I couldn’t reach the office by the phone number posted on the front door! So I was late for my appointment even though I arrived 30 minutes early! The only way that I finally got in to see that Doctor was when another person came out of the building just be chance. So all the confusion made me frustrated, especially because I’ve had to wait two and a half months for my appointment!
