Welcome to Team Aspire!

Aspire Allergy & Sinus is a group of passionate people who have come together to reinforce our cause: curing patients who suffer from allergy and sinus problems. We take great pride in the enthusiastic, talented and diverse workforce that make up our team, and we’re so glad you are now a part of it!

Our Story

It all started in 2012, when a small team led by Austin Allergist, Dr. Chris Thompson, wanted to address the needs of the many who suffer from allergies and simply don’t have the time to come into an office to get their allergy shot each week. For many of these patients, there was no other option if they couldn’t take the allergy shots. Rather than leaving these people to suffer from allergy symptoms and treating them with over the counter medications with no long-term solution, Aspire Allergy & Sinus (formerly Texan Allergy) was created to offer a convenient, affordable, and safe alternative to allergy shots: allergy drops, our signature treatment.

Since then we have expanded our service options to food allergy testing and treatment, exceptional sinus care with a variety of in-office solutions, and a completely new and innovative therapy to treat environmental allergens, the ExACT Immunoplasty procedure.

Headquartered in Austin, TX, we have clinics in Colorado, Florida, New Mexico and Texas. With excellent patient care as our guide, we are always expanding to accommodate more patients; making it easy to get the allergy and sinus care that so many need.
