Work With Sandra

Blending her background as both an athlete and dietitian, Sandra helps clients fuel for performance, recovery, and everyday energy—while rebuilding trust with food and body along the way. Whether you’re chasing a marathon PB, training for your first ultra, or learning to fuel consistently after injury or burnout, Sandra helps make nutrition practical, personalized, and empowering.

When she isn’t working or trail running…

you can still find her in the mountains – mountain biking, hiking, snowboarding, cross-country skiing – or training her cat, Midnight.
