Texan Allergy & Sinus Center, the largest allergy company in the state, opened a new Cypress clinic Dec. 3 at 21212 Hwy. 290, Ste. 385. TASC uses a process to treat allergies known as sublingual immunotherapy—or allergy drops—which is available for patients as young as six 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 Cypress 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 and Sugar Land clinics are up and running, and three additional clinics are planned for The Woodlands, uptown Houston and Pearland. 713-766-5437. www.texanallergy.com
