    *Dr. Boonyaputthikul was not the doctor assigned as my primary, and to be honest, I more or less selected that dr. at random. *Dr. B. was available sooner for my first appt. After this visit, I am requesting to change to have *Dr. B. as my primary, as I have great confidence in him.
    Dr. Boon and Diana, his nurse assistant, were friendly, professional and were a pleasure to work with!!!!!!
    *Dr. Boon is very sharp. Knows his stuff. Easy to talk to.
    I should have asked for more instructions on how and when to use inhaler.
    Dr. took the time to talk with me. I thanked him for actually taking time for all I had to discuss.
