“Allergy and immunology is my specialty of choice because it is a fascinating field—allergies and asthma are affecting more and more people every year. Whether it is allergic rhinitis, asthma or food allergy, exciting, cutting-edge research is ongoing in our specialty. I obtained my Ph.D. in genetics and enjoy applying that knowledge to the diagnosis and treatment of my patients.”

“I take delight in hearing that my patient’s allergy and asthma symptoms have improved after receiving treatments such as immunotherapy and other desensitization procedures. It is personally gratifying to help my patients navigate family and school life with food allergies which can be potentially life-threatening. I enjoy building long-lasting relationships with my patients and their families while striving to provide them with the best healthcare possible. I try to treat others the way I would want to be treated—with compassion and dignity. It is a privilege to be able to help someone feel better and improve their quality of life.”

“I went into medicine because I enjoy helping people and it is a noble profession. As my father always says, “Health is wealth” and I truly believe this. Good health is a blessing and should never be taken for granted.”

Dr. Foster has been in practice since 2009 and is a board-certified allergist and immunologist.  She specializes in the care of children and adults with allergies, asthma, immune and respiratory disorders. Her areas of interest include management of food and drug allergies, contact dermatitis, asthma and eczema in children and adults.

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.
