“My own problems with allergies have given me a clear understanding of how allergies and asthma can affect lives, especially the lives of children and young adults. I have always known that I wanted to be a doctor, but my post-residency interests as a medical school professor and immunology researcher at Texas Children’s Hospital and later as a physician in private practice were shaped by my personal experiences. I understand the struggles, the frustrations, and the life-changing effects these conditions have on my patients. I am committed to providing top-notch care and finding solutions to my patients’ allergy and asthma problems.”

“As a medical field, allergy and immunology has made great strides in the last generation. We have a much better understanding of the mechanisms involved in allergic diseases and asthma. We are much better able to diagnose and treat allergic conditions and reduce or even eliminate their effects on the people we see in practice. It is a great time to be working in this field. My professional commitment is to get to know my patients and their families, to understand their concerns, and to fully inform them of my medical opinions–to enlist my patients as active partners in confronting their allergy-derived health concerns.”

Dr. Samuel Foster has been in practice since 2006 and is a board-certified allergist and immunologist. He specializes in the care of adults and children with allergies, asthma, and other immune disorders. His special interests include management of recurrent infections (immune deficiencies) in children and adults as well as allergic skin and gastrointestinal disorders. Dr. Foster has received many awards for excellence in his clinical and research endeavors at the prestigious Baylor College of Medicine. He also has numerous publications related to asthma and immune deficiencies in prominent scientific journals.

Oral immunotherapy / OIT

Our physicians are among a select group of doctors in the United States with extensive experience in oral food desensitization. Our physicians have over 10 years of shared experience with oral immunotherapy. They have successfully desensitized patients of all ages to allergenic foods including peanuts, tree nuts, milk, eggs, soy, wheat and shrimp. In our oral immunotherapy program, the concerning food item is gradually reintroduced, starting with tiny doses and increasing slowly to the full dose over the course of 4-6 months. This form of immunotherapy is conducted only under close medical supervision in our clinic with weekly office visits and oral challenges. Our physicians can evaluate for food allergy and determine whether oral immunotherapy should be considered.
