First things first: I love chocolate. I love kale. And I consume them both regularly, but generally not at the same time (although, ask me about my chocolate, berry & kale smoothie!) I also love helping people find easy ways make their body, mind, and life better while also making eco-friendly choices that support the health of our planet.
