Rebekah is originally from Columbus, Ohio, and the daughter of two teachers. You could say teaching runs in the family. In August 2013 Rebekah graduated from Concordia University in Seward, Nebraska, with a Bachelor's degree in Elementary Childhood Education. Then, in December 2013 Rebekah completed the colloquy for her Lutheran Teaching Diploma.

Rebekah taught 2nd grade at Trinity Lutheran Elementary in Grand Island, Nebraska from August 2013 through May 2017. While teaching in Grand Island, Nebraska she met her husband, Jens Petersen. The two married June 9th, 2017, and reside in Elkhorn, Nebraska. Their daughter, Harlow, joined their family in 2020. Jens is an Omaha Firefighter, and Rebekah serves as Concordia Academy's 3rd grade teacher.

In Rebekah’s free time she enjoys snuggle sessions with her beloved Shih Tzu, Scout, as well as reading, traveling, and coffee dates with friends.

Mrs. Petersen's favorite Bible verse is Proverbs 3:5-6: “Trust in the Lord with all your heart, and do not lean on your own understanding. In all your ways acknowledge him, and he will make straight your paths.”
