Learn more about Dr. Jellinek

I have been pediatric and adolescent physician for over 28 years. I worked for ten years in Virginia at my father’s pediatric practice which started in the basement of our home over 50 years ago.  My husband and our then two-year-old triplets the relocated to Pennsylvania where I worked for a large pediatric practice for four years and then opened my solo pediatric practice in Pennsylvania in 2004.

In 2010, I began studying the effect of epigenetics on clinical disease due to unanswered questions with my own family members.  My strong science and research foundation allowed me to apply this new and exciting discipline to my own patients with complex neuroimmune syndromes with promising results.  I have had dramatic success analyzing my patients’ genetic data to pinpoint the cause of their symptoms and offer a more directed personalized treatment plan that is often safer, cheaper, and does not just cover up their symptoms.

This personalized targeted therapy has been utilized in many cancer, infertility, and cardiac centers, but has been greatly underutilized in clinical practice.  With this advanced technology, I am able to show exactly where genetic weaknesses reside in the production of neurotransmitters required for optimal psychological health. This technique can also demonstrate nutritional deficiencies in the breakdown of important vitamins needed for hormone, immune, and enzyme function.

I have had success decreasing traditional medications for ADD/ADHD, anxiety, depression, obsessive compulsive disorders, severe allergies and eczema, sleep disorders, autism, recurrent infection, gluten sensitivity and irritable bowel syndrome, migraines, learning disorders, and social anxiety to name a few!  I have treated all of these illnesses traditionally, and I continued to do so, BUT there are other factors outside the box that MUST be addressed when treating complex disease.
