Dr Ruddy, is very patient and took the time to answer all of my questions. He shared with me - my sleep chart, progress I had made being on the machine after 1 year and options for traveling with a travel cpac machine.

In addition, she answers my questions in a thoughtful and meaningful way, all the while showing genuine compassion for me, as the patient.

I was met promptly (I was a few minutes late...), Aiko took me to her office, and explained in simple language ALL of the results of my "sleep testing", both the good and the not so good. She was patient, and professional throughout!

My appointment started right on time, no delay. NP Aiko Loo provided current CPAP readings and provided feedback on my progress. She explained how the machine is adjusting to my breathing and suggested some adjustments based on her findings. She is very knowledgeable and easy to talk to. I'm having a bit of trouble with my current mask so she made various suggestions and showed me some options in different masks. Great experience working with NP Loo.
