Anna grew up in Houston, Texas, but has also lived in Wellesley (Massachusetts), Austin, Memphis, Chicago, and now Bloomington, IN. She’s also spent extensive time in Latin America both as a child (in Maracay, Venezuela) and as an adult (in Lima, Peru), where she learned to speak fluent Spanish. In her spare time, Anna enjoys anything that gets her outside, especially hiking, kayaking, horse-back riding, and gardening. She is an avid trekker and especially loves trekking in the Peruvian Andes. She is particularly excited to spend more time in Colorado, exploring the Rockies. When she’s home in Indiana, she spends time volunteering at a local therapeutic riding center, battling the weeds in her garden, and serving as a heated cat bed for her cats.

She’s a former lacrosse player, and during graduate school, she had a great time volunteering as a high school lacrosse coach; something she hopes to do again someday. Sarah’s also passionate about photography; both as an artistic endeavor and as a side gig. She’s really excited to be back in Colorado and particularly in the Western Slopes, a place she has always hoped to spend more time.
