I’m Lauren, a holistic Registered Dietitian who supports women with PCOS in their 20s through early 40s achieve regular periods with less pain, bloating, and fatigue so they can regain control of their cycles, improve fertility outcomes, and protect their future health against PCOS-related risks. Unlike one-size-fits-all solutions like birth control, restrictive diets, or cookie-cutter group programs, my collaborative and personalized approach empowers clients to build trust in themselves while learning how to best nourish their bodies through tailored and realistic nutrition, lifestyle, and supplement strategies.
