Sundberg was born in Phoenix, Arizona and played high school football at North Canyon High School. He played left tackle until his junior season, when the coaches moved him to center. Since the previous long snapper had graduated, his coaches also made him the long snapper that season. It was at this point, that Sundberg began training with Ben Bernard. Ben Bernard was Sundberg's offensive and defensive line coach at North Canyon. Sundberg also trained under him to become a better long snapper. They trained 5–6 days a week including lifting weights after Sundberg's senior season. Under Bernard's tutelage, Nick was able to earn a full scholarship to the University of California Berkeley. Sundberg continues to train with Bernard every off-season in Phoenix and now assists him in the training of younger long snappers. During his senior year, Sundberg was the team's captain and was named All-region honorable mention. Sundberg also participated in wrestling and track and field at North Canyon.
