With a Bachelor’s in Interdisciplinary Health Services, a Master’s in Occupational Therapy, and certifications including the M2 Performance Nutrition Education Series, & Precision Nutrition Level 1, Christa blends science-backed strategies with a deeply personal approach to health and performance.
As a practicing Occupational Therapist, Christa has worked across hospital and clinical settings—giving her a unique ability to meet clients exactly where they are, whether they’re striving for athletic performance or taking their very first steps toward healthier habits. She’s especially passionate about helping women overcome under-fueling and guiding them toward strength, energy, and resilience.Her own journey has shaped the heart of her coaching. After navigating gymnastics injuries, body image struggles, yo-yo dieting, and being dependent on medication for severe acid reflux, Christa discovered the transformative power of nutrition. That discovery didn’t just help her get off medication—it fueled a deeper calling to help others unlock their health through a holistic, sustainable approach.
Christa’s coaching philosophy is rooted in growth, not perfection. She finds the most fulfillment in celebrating her clients’ wins—whether it’s hitting a new PR, feeling energized again, or simply developing pride in consistent choices. “It’s an honor to be part of someone’s health journey,” she says, and it’s clear she means it.
She thrives when working with open-minded, committed clients—whether they’re chasing competitive goals or simply ready for change.
Outside of coaching, Christa enjoys spending time with friends and family, watching reality TV and comedies, and getting outdoors when she can.
Client Testimonials
Eir S.
"I have never felt like I’ve been on a diet, I have been able to enjoy weekends with friends, family dinners and eating out, and still reaching my goals. She has a solid knowledge base which makes her able to fit your needs, as well as backing up her choices and recommendations with science. She always makes time for me, and has felt like a friend and a great supporter cheering me on. I would recommend Christa to anyone who are interested in coaching."

"It was wonderful. Christa was a coach, mentor, guide, therapist, friend and everything I needed her to be. She gave her time, expertise, knowledge, and love. She gave tough love when it was needed and held my hand no matter what. I’ll miss our biweekly check ins, but we will keep in touch with life updates."
