Meet the Author

Homeschooling mum and children’s author Kirstie Marx writes from a life shaped by faith, family, and her childhood in Denmark. Born in England and raised among Danish traditions from the age of eight, Kirstie fell in love with the simple, cozy rhythms of Scandinavian life — the very inspiration behind The Blessing Nisser. Her stories invite families to slow down, serve one another, and celebrate Christmas with purpose.

​

Kirstie also has more than 35 years as a PTR‑certified tennis professional, coaching players of all ages and abilities. She has served at Kildaire Farms Racquet & Tennis Club since 2005 and is known for her energy, encouragement, and heart for player development. Her dedication to tennis education has earned her numerous honors, including the International Tennis Hall of Fame Education Merit Award, multiple USTA Education and Service Awards, and selection to the 2026 Women Who Rally Global Leadership Cohort.

​

Kirstie’s passion for service extends far beyond the court. For over 11 years, she directed Special Olympics Tennis and helped found Abilities Tennis, a nonprofit expanding opportunities for athletes with intellectual disabilities. Her work in adaptive tennis inspired the creation of the PEAT curriculum, now used in schools across Wake County.

​

At home, Kirstie has spent 15 years homeschooling her two daughters, sharing her love of learning with fellow homeschool mums and pouring into her family with joy and intention. She lives in Cary, North Carolina, with her husband of 30 years, Rich. Her newest joy is her granddaughter, who lovingly calls her “Poppy.”

​

Drawing from her Danish childhood, her heart for service, and her deep faith, Kirstie created The Blessing Nisser — a story that helps families keep Christmas simple, meaningful, and full of love.
