Welcome
I’m Jessica Marshall Regan, a Registered Dietitian Nutritionist (RDN), Licensed Dietitian Nutritionist (LDN), Functional Medicine Nutritionist (FMN), and Certified LEAP Therapist. I specialize in functional and integrative nutrition, with a passion for helping individuals reclaim their health by addressing the root causes of imbalance—especially when it comes to hormone health, digestive issues, and chronic inflammation.
Using a whole-body approach, I provide Medical Nutrition Therapy for disease management and prevention, weight concerns, and overall wellness. My work is grounded in evidence-based science and personalized care, allowing me to create sustainable behavior change that supports long-term healing and vitality.
As a certified LEAP therapist, I’m trained in using the Mediator Release Test (MRT) to identify and treat food sensitivities that may be driving symptoms like migraines, fibromyalgia, IBS, GERD, and other gastrointestinal disorders. From there, I tailor dietary interventions that reduce inflammation, support the gut microbiome, and calm autoimmune flare-ups.
Hormone balance is a key part of my practice—because when your gut and immune system are in sync, your hormones follow.
