Holistic Health & Athlethic Performance Coaching
A holistic approach to sustainable health, backed by science
Welcome to Habitually Holistic!
Hi, my name is Siri. I am a sports nutritionist (CISSN) & athletic performance coach :) I help athletes (& non-athletes!) build sustainable habits to take their sport & health to the next level. My background is in athletic performance & coaching, biomechanics, human biochemistry & biology, and functional nutrition. After drastically improving my health and sports performance through integrative nutrition & lifestyle changes, I now help others to do the same.
I'm here to help you finally make health sustainable by taking a holistic approach and optimizing your nutrition & lifestyle habits.
I want you to show up as your strongest self for you & yours for years to come!

"You've unlocked more than 24hrs in my day. My eating patterns now add energy & focus to my day, rather than take away from it. You've made changing simple! Keep it up!"
"Siri DeMarche is a wonderful coach--I can't recommend her enough. I've been through two personal programs with her (targeting different areas of my nutrition) and have created a lasting healthy lifestyle that I am actually excited to continue."
"I started working with Habitually Holistic after a string of failed attempts to get healthier. Siri has a shame-free, sustainable, well-rounded approach that doesn't obsess over numbers or quick fixes. If you want an approachable & compassionate coach that can help you get on track while providing the background science for her recommendations, please check her out! Highly recommend. "
