Reviews For This Clinic

"Knowledgeable, Fun, & Kind"

The staff was knowledgeable, fun and kind. I had issues in the past with an allergist not approving me for shots because I “wasn’t allergic enough, only mildly allergic to a lot of things”. I was nervous so I asked them up front and they said if I show any reaction at all they would happily help me. I am so excited to get started on the drops which will be so much more convenient than shots. Finally I can work towards relief, I just needed a good allergist.

""Impressed with the Staff"

I was very impressed with the staff there. I got my first allergy test a few weeks ago. Got great results and mostly thankful I was not allergic to pets. Crystal Salazar was awesome and caring and really attended to my every need with love and care. I couldn't ask for any better. I recommend you see them if you suffer from allergies. Got my drops today so will put another review when there are improvements.

"Highly Recommend this Office!"

Amazing! The staff and doctors were very helpful and knowledgeable. They were transparent about services and costs before starting so I wasn’t surprised at the end of the appointment. What I appreciated the most was how the doctor listened to me and I felt that she genuinely wants me to feel better. They were all accommodating and understanding, I never once felt pressured into procedures or testing and was explained all of my options. I highly recommend this office.

– J. F.
