Brett Helquist was born in Ganado, Arizona, and grew up in Orem, Utah. He entered Brigham Young University as an engineering major, but soon realized this was not the right choice for him. Having decided to take time off from college, he headed to Taiwan where he stumbled into a job illustrating English textbooks, which he enjoyed. There, a friend introduced him to an illustration student, also from Brigham Young University. This introduction inspired Brett to eventually switch majors. After spending a year in Taiwan, he went back to BYU and transferred to the illustration department. In 1993 he received a fine arts degree in illustration.
