Outside of the office, Lindsay can be found on the tee box, ski hill, or in front of her art easel. She enjoys spending Saturday mornings having coffee with her grandparents and playing with her nieces and nephews. As community involvement is important to Lindsay, you may also find her volunteering for various organizations in the Harrisburg and Sioux Falls communities.
