Chief Operations Officer


Karen L. Herb, MS CNS LDN holds a master’s degree in Functional Nutrition from the University of Bridgeport, CT. She is a Certified Nutrition Specialist (CNS) and a Licensed Dietary Nutritionist in the state of Maryland and the District of Columbia.

Firmly rooted in the foundations of Functional Nutrition, Karen’s clinical approach focuses on education and the power of small changes. Seeing the need for widespread education on the principals of food quality, environmental exposures, and lifestyle choices, she is passionate about teaching individuals how these foundations affect wellness. She knows that this knowledge coupled with small changes can have a huge impact on health. She loves navigating people through small changes that add up to big wellness. She finds it very rewarding to help individuals gain a sense of ownership for their wellbeing and learn to approach health from a “root cause” perspective.

In her role as Chief Operations Officer for Dr. Fitzgerald’s clinic and her education programs, Karen is able to further her mission to spread the Functional movement. She is committed to creating opportunities to bring Functional Medicine and Nutrition to a broader community; increasing patient access to functional care and practitioner access to education and mentorship.

When she steps away from the clinic, you’ll likely find Karen playing with her dogs or perhaps in a downward dog.
