North Texas is often referred to as the “Allergy Belt”. There are numerous people who suffer from sinus pressure, headaches, itchy and watery eyes, sinus drainage, nasal discharge and chronic cough. These can all be signs and symptoms of severe environmental allergies and possibly even chronic sinusitis.
The Allergy and Sinus Center is dedicated to finding a definitive diagnosis and offer treatment options. This is all offered in the convenience of our two locations. This can involve radiologic imaging, medical therapy including allergy shots, and possibly surgery. Our McKinney office also boasts an on-site CT scanner.

We also now offer Sublingual Immunotherapy (SLIT) which allows the patient to treat their allergies at home, safely and effectively, without shots.  Please contact our office for further details.

 Home Maintenance Allergy Patients and Sublingual Allergy Patients may now order their serum vial refills online.  Click button to be redirected to a secure server.
