Dr. Klaiber is a double board-certified physician who grew up in a small town about 30 miles north of New Haven Connecticut. He was first drawn to the study of Allergy and Immunology as an undergraduate student.
“I was intrigued by the fact that we all possess this immensely complex network of cells constantly working behind the scenes to stave off infection.”
Dr. Klaiber earned his M.D. from Eastern Virginia Medical School and completed his pediatric post-graduate residency training at VCU Medical Center in Richmond. He remained at VCU to complete his Allergy Immunology fellowship. He enjoys treating both Pediatric and Adult Allergy and Immunology patients. Dr. Klaiber also has experience using oral immunotherapy (OIT) to treat food allergies.
“Over the course of my fellowship I was fortunate to have several excellent clinical mentors. Working closely with these individuals allowed me to gain firsthand experience both with rare disorders such as Mastocytosis and HAE, in addition to providing regular exposure to more common diseases, like eczema, food allergy, asthma, allergic rhinitis, CVID and chronic hives.”
Dr. Dawson completed her fellowship in Adult and Pediatric Allergy and Immunology. While training at the University of South Florida-Johns Hopkins All Children’s Hospital in St. Petersburg, Florida, she had the honor of serving as Chief-Fellow. Dr. Dawson has participated in clinical research, published in the Frontiers of Immunology, and presented her work at national conferences including the American Academy of Allergy, Asthma, and Immunology and Clinical Immunology Society.
While her interest in the field of Allergy and Immunology was sparked by the complexity of the immune system, what ultimately led Dr. Dawson to pursue the field is the ability to provide care to patients of all ages with a wide variety of allergic/immunologic diseases.
Dr. Dawson has managed patients with rare and complex immunodeficiencies and autoimmune conditions, in addition to more common allergic disorders, such as asthma, allergic rhinitis, eczema, and food allergy. Her areas of clinical interest include food allergy, oral immunotherapy, drug allergy, severe eczema, chronic hives, and primary immunodeficiency.
Dr. Dawson’s approach to patient care is centered on evidence-based medicine and shared decision making. “I take the time to listen to my patients and their concerns. I want them to understand their medical diagnosis and treatment options. Together we can then establish a treatment plan that will be most effective for them.”
Her personal interests include gardening, photography, and yoga. In her spare time, she enjoys staying active and engaging in outdoor activities such as hiking and running with her husband.
