Allergist Takes a Preventive Approach to Seasonal and Food Allergies, Skin Conditions and Asthma

“Allergies are the 6th leading cause of chronic illness in the U.S. and the most common health issue affecting children; as allergists, there is a lot we can do.”

Dr. Debora Geller has managed the challenges patients face caused by environmental allergies, asthma, atopic dermatitis or eczema, hives and other skin allergies, food allergies, medication allergies and more. “Allergies can severely impact one’s ability to function” she said. “Yet there is a lot we can do to relieve those symptoms—and even prevent them in the future.” Trained in pediatric and adult allergy, asthma and immunology, Dr. Geller has helped countless patients with focused, personalized approaches to manage their allergy symptoms on a daily basis.

Helping others is a calling for Dr. Geller, and has been since she was very young. At just six years of age, she aspired to follow in the footsteps of her pediatrician, a woman who formed a strong connection with her. After medical school, she completed a residency in general pediatrics, then a fellowship in pediatric and adult allergy, asthma and immunology.

Dr. Geller traditionally sees patients who require more intensive allergy care than what is available over-the-counter or by their primary care physicians.  “These may be patients with moderate or severe cases that need a higher level of treatment,” she said. “My goal is to keep them healthy and functioning.”

Dr. Geller chose to work at Vanguard for its preventative and collaborative care approach. She noted, “It makes for better patient care, when the medical team works together with a similar focus.” Dr. Geller’s caring and personalized medical approach has earned her such awards as NJ Monthly Top Doctor, Castle Connolly Top Doctor and the Top Doctor for Children.

When she’s not working, Dr. Geller enjoys traveling and learning about different cultures. She is an athlete and enjoys cycling and skiing. She stays active with her husband, also a physician, and three kids. She has a rescue Shih-Tzu named Sandy.
