The appointment I had was for a standard allergy test to determine why I have been having severe allergic reactions. I saw Dr. Diaz after the preliminary testing (over $1.3k for 5 minutes of her time) at their office and was told my results require me to go to Quest and obtain a blood test. After Quest, I was told by Dr. Diaz' office that I do not need to come in and discuss the results because I am not allergic to anything worth noting and nothing worthy of an appointment came up on my results. This was of course overwhelmingly disappointing as I have had my throat close up due to an allergic reaction, yet, an allergist cannot help determine why? My eyes will also swell up time to time to the point I can no longer see as well - I even shared these disturbing photos with the doctor. After over $1k in bills from this office, I am told I have no allergies of concern even though I know I continue to have serious allergic reactions to something but I still do not know how to prevent it!… Waste of time sadly.

I went to see Dr.Diaz several months ago.I have had allergies for many years.She was wonderful.She explained the testing.She told me exactly what to expect( nobody likes surprises).After the tests came back & I had several allergies: we discussed options.We decided to have the allergy shots.I was going twice a week, then once a week & now I go once a month.I was in my backyard the other day & I chuckeled to my self as pollen was falling all around me & I had no reaction.Whenever I go to the office to get my shots Dr.Diaz always goes out of her way to say hello & ask how I am doing.She does this with a smile that would lite up any room.I must say that her staff are mirror images of her ( especially Christina & Nancy).They always make you feel like you are special.I have & will continue to reccommend Dr.Diaz & her staff to anyone who has allergy issues
