About Ashley

As a board-certified sports dietitian with a Master’s degree in Nutrition and Physiology from Columbia University, my goal empower athletes and athletic people to fuel with purpose and live with intention. With years of experience working across professional sports, collegiate athletics, and private practice, I specialize in helping individuals optimize performance, recovery, and long-term health through personalized, evidence-based nutrition strategies. At Nourish, I work with clients 1:1 to develop customized fueling plans that align with their training demands, lifestyle, and goals. From managing energy availability and hydration to navigating travel, competition, and recovery, I help take the guesswork out of nutrition—so you can focus on showing up as your best self, every day. Whether you're a professional athlete, student-athlete, or simply someone looking to optimize how you feel and function, I’m here to guide, educate, and support you every step of the way.

Approach to care

My approach to nutrition is rooted in science, driven by performance, and centered around the individual. I believe that effective nutrition support goes beyond meal plans—it’s about understanding each client’s unique goals, physiology, training demands, and lifestyle. Whether you're an elite athlete or simply striving to feel and function your best, I provide personalized, evidence-based strategies that evolve with you. I prioritize education, consistency, and a collaborative partnership, ensuring that every recommendation is practical, sustainable, and aligned with your real-world routines. From fueling for performance and recovery to managing energy, hydration, and travel, I help clients build confidence in their nutrition choices—without restriction or one-size-fits-all solutions. At the core of my care is this belief: when you fuel with purpose, you unlock your full potential.
