Get to know Michelle:

  • In her free time: Michelle, her husband, and their two young children spend as much time as they can outside. Whether camping, hiking, swimming, skiing, or jumping off a rope swing, they find joy together as a family in the great outdoors.
  • You might be surprised to learn: Michelle is terrified of heights. In an attempt to overcome that fear, she has bungee-jumped at the highest jump in the world (South Africa) and gone skydiving. That said, she still gets nauseous when looking over a third-story balcony.
  • The wellness advice she gives her friends: Find what works for you and aligns with your value system. “Nourishing and moving our bodies, doing things that bring joy, and prioritizing sleep and mental health are all ways that we can become the healthiest version of ourselves,” she adds.
