Dr. Wu is always very pleasant and thorough. He's always appropriate and on point. I did not feel rushed at all, and while my appointment was not on time, I do not mind because I know he is spending time helping a patient and when it comes to my turn, he will do the same.

I love Dr. Wu, he always asks me, what's new and I tell him all my new things in my life. After all that, we talk all about my RLS. He really cares

Dr. Wu took an appropriate amount of time for the appointment. He spoke directly to me, and at one point, asked his assistant to send him information from my online CPAP account. She was quick! Dr. Wu decided on a course of action to try to resolve my sleep problems, and asked me to schedule a next appointment.
