Texan Allergy & Sinus Center, the largest allergy company in the state, opened a new clinic Dec. 26 at 1011 Medical Plaza, Level 2, The Woodlands. TASC uses a process to treat allergies known as sublingual immunotherapy—or allergy drops—which is available for patients as young as 6 months old, according to a company press release. The clinic also offers food allergy treatment called oral immunotherapy as well as various sinus procedures, such as balloon sinuplasty. The Woodlands location is a part of a broader effort spearheaded by board-certified allergist Dr. Rubina Wahid to open six new Greater Houston-area locations. Katy, Sugar Land and Cypress clinics are up and running, and two additional clinics are planned for uptown Houston and Pearland. 713-766-5437. www.texanallergy.com
