More About Me

I love the outdoors and take every chance I get to go hiking, biking, camping, or paddle boarding. I’m also passionate about exploring international cuisine — trying new recipes and discovering new restaurants is one of the ways I connect food with both joy and wellness. For me, nutrition is a way of life that’s as much about pleasure as it is about health.
