      Excellent doctor that takes the time to listen to your complaints. She will personalize your care based on your needs. Glad I found her at the start of the allergy season.

      I went with my 2 (7 and 9) daughters for allergy testing, we all liked her a lot. The staff was very nice and caring as well. We had visited a different allergist down in Phoenix and they were nice, but I wanted a new start, as fresh opinion, as our situation has changed. I am very glad we did.
