About Me

I’m a functional nutritionist with a B.S. in Biomedical Science, an M.S. in Human Nutrition, and advanced credentials as a Certified Nutrition Specialist (CNS®) and Licensed Dietitian Nutritionist (LDN). My approach blends science-backed strategies with real-life experience on the trail—because as an avid trail runner, mountaineer, and backcountry skier living in Colorado, I understand firsthand the demands outdoor athletes place on their bodies.

Over the course of my career, I’ve had the privilege of working with more than 400 clients in multiple medical clinics and my private nutrition practice, helping them fuel smarter, recover faster, optimize their gut health and hormones, and feel more energized for daily life and the adventures they love. Whether you’re training for your first trail half-marathon, your next ultra, or just trying to keep your energy up on long runs, I’d love to help you find the nutrition strategies that work for your body and goals!

"Look deep into nature, and then you will understand everything better."

About My Business

In my nutrition practice, I help outdoor enthusiasts confidently fuel their bodies for sustained energy, smooth digestion, and stress resilience, so that they can unlock peak performance and feel their best in daily life and during trail running, mountain biking, climbing, and beyond.

Unlike one-size-fits-all sports nutrition approaches, I use targeted functional nutrition strategies based on the latest research, lab testing, supplements, and lifestyle upgrades – to elevate whole-body health for daily life and epic outdoor adventures.

My approach to sports nutrition is highly personalized, root-cause focused, and built for lasting results—not quick fixes. If you’re looking for a short-term band aid, I may not be the right fit. But if you’re ready to dig deep and truly optimize your health, performance, and recovery, you’re in the right place!

We’ll commit to working together for at least a couple of months, giving your body the time and support it needs to respond and adapt. Throughout that process, you can expect close guidance every step of the way.

For those who are unfamiliar with functional nutrition (a key part of my practice) – functional nutrition is a personalized approach to health that focuses on using food as medicine, considering an individual’s unique needs, lifestyle, and underlying root causes of health issues to promote optimal well-being and performance.
