Patient Reviews

I had a very good experience. They took the time to call me when insurance rejected the claim for my daughter's visit, then they resubmitted the claim and called me when it was approved. I really appreciated this because usually you only get a call when something is wrong. But the staff at this office called me with good news, which was a relief and also very considerate.

Let us help you

Do you or your child suffer from asthma, nasal congestion, sneezing, wheezing, itching, watery eyes, rashes, or other allergy symptoms? When your body rejects common substances such as foods, pollen, pet dander, medications, or metals, you lose. We understand the toll that uncontrolled allergies can take on your health and quality of life, and we want to help.

You are neither alone nor helpless in your battle against allergy symptoms. Accurate diagnosis is the first step to taking your life back. Diagnostic procedures such as food allergy testing and lung function testing are used to determine the nature of the problem. Once your allergic triggers have been precisely identified, avoiding them becomes possible. Even better, many allergies can be eliminated or controlled with treatments such as immunotherapy allergy treatment.
