Aiko Loo is a pleasure to talk to. So calm, has a pleasant and relaxing voice, she listens to her clients. She answers all your questions. I am a critical care nurse who went to her office for a follow-up appt on the results of my sleep study and she very kindly gave me other information that, as an NP and who specializes in her specialty, I do not know. She is also very knowledgeable in her specialty.
