Lowder was born in St. Louis, Missouri, but his family moved to Pleasantville, New York in Westchester County when Kyle was six years old. Lowder excelled in both athletics and performing arts during his four years at Pleasantville High School. He was quarterback of the Pleasantville Panthers, All New York State in Track and Field in the 800 meter event, and still found time to star in many theatrical productions and participate in the All New York State Choir. Lowder had the honor of competing alongside athletes from all over the world in the International High School Track Championships. "I was really busy in high school," reflects the young actor.

During his senior year of high school, Kyle decided that performing arts was truly his passion over sports and was accepted into the prestigious Syracuse University Drama Department. After the first semester of his sophomore year, Kyle flew to Los Angeles to participate in a series of workshops and showcases for actors. The response from agents and managers was overwhelming, so much in fact that Kyle decided upon a leave of absence from college to stay in Los Angeles to follow his dream. "At first my parents were not that thrilled that I was putting school off for a while, but after only a few weeks being in Hollywood, I was booking jobs and having great meetings, but most importantly, I was able to support myself, so my parents came around."

Lowder appeared in several national campaigns and runway shows for Abercrombie & Fitch and Speedo before landing the heavily anticipated role of Brady.

Lowder has two younger brothers; Travis attends the University of Colorado and youngest brother Cameron is a sophomore in high school. Kyle's father, Craig, is the director of communications for IBM and his mother, Susan, teaches middle school.

In his spare time, Kyle enjoys working out, going to the beach, and is a self professed movie buff.

Kyle stands 6' 1" and has blonde hair and blue eyes. A Virgo, he celebrates his birthday on August 27th.
