Dr. Armstrong is a good doctor. I trust him with my health. His M.A. was efficient. She washed her hands when she came in the room and washed them when she left the room. Dr. Armstrong came in, sat down, greeted me politely. I greeted him back as such and we talked about my situation. He gave me some good advice. He asked me to stay out of the heat because the heat sometimes triggers my asthma episodes. I had a very pleasant visit with him and I thank God that he's my good doctor. Thank you.

You will not find a better doctor that genuinely cares and takes your health seriously. I have told and recommended to many of my friends and family about my Pulmonologist . This day and time it is very rare to find a doctor that will take time with you and work to make you feel better and always tells me that if I'm no better to not wait till the next appointment to call him. He truly is a wonderful doctor.
