Eric S. Applebaum, MD, FACAAI - Parsippany, NJ

“I had a longstanding interest in how the immune system works. Allergy and immunology was a way to pursue my interest in caring for patients. I also enjoyed the idea of specializing; becoming an expert in one area rather than trying to remain competent in all areas as a generalist. I was interested in seeing patients of all ages, especially multiple family members. I wanted to make a difference in patients’ lives and help with illnesses often ignored by other physicians.

“I most enjoy seeing how much better patients feel and how quickly they realize that they have been suffering unnecessarily for such very long periods of time. I treat patients like intelligent people capable of understanding their conditions and the treatment options available. I treat patients the way I want to be treated when I have to see a doctor. I want my patients to know that there are no hopeless cases. I am their advocate in every way they need me for their allergic problems. I take it as a personal challenge to help them live better.”

When not working, Dr. Applebaum enjoys spending time with his wife and daughters, traveling, watching pro basketball, reading and cooking.

Julie Anne Sosa, LPN and Office Manager - Parsippany,  NJ

“I enjoy working here because while we are making an improvement in our patients’ health, we develop interpersonal relationships with our patients and their families on a professional level. As a longtime allergy sufferer myself, I see the importance of treatment. Following patients from an initial visit through testing and then a step further by actually treating the underlying cause of their many years of suffering, it is rewarding to see the relief they experience when they are properly cared for."

Favorite Quote: "Don't ever let anybody tell you you're not good enough."


 Priscilla Leon, Office Manager

Favorite Quote: "I enjoy working in the allergy field as I can see the transition in patients from when they start treatment (a not so happy patient), to a patient that constantly praises how much better they are feeling ever since treatment began with Dr. Applebaum."
