Born in Port Lavaca, Orta moved to Lubbock at age six. Despite the roughly 540-mile initial relocation from south to north Texas, Orta's family kept moving within Lubbock city limits. Orta attended Haynes Elementary School, Mackenzie Junior High School, Evans Middle School, Matthews Junior High School and Lubbock High School before graduating from Coronado High School.
Orta was given his first guitar—a red, no-brand toy—by his aunt when he was four, which he taught himself to play.
At age 18, Orta left home, and although he had a job, he couldn't afford to pay both rent and for the black Steinberger guitar he had financed from Jent's House of Music. Choosing his guitar over a home, he lived in his car, slept in open churches and showered at the YMCA for a year. He eventually landed a job at Jent's, where he fell under the tutelage of co-worker and revered local guitarist, John Ellis. Ellis was surprised by Orta's melodic lines and fast playing ability, which he says often don't go hand in hand. He was also surprised that Orta had never heard of music greats, like Jimi Hendrix, Led Zeppelin or Van Halen, all of which he had been deprived of hearing as a child with no electronics made available to him.
In 1996, Orta moved to Nashville and joined Petra; he contributed greatly to the band's success in the late 90s. His awards include a Gold Record, a Dove Award, three Grammy Nominations and for Gospel Rock Album of the year was presented a Grammy in the year 2000 for the award winning album, Double Take.

In 2001, his solo album, Born Again on Word Records was finally released to rave reviews and rock radio success, which culminated in a 2002 Dove Award Nomination for Rock Recorded Song of the Year.

In 2009, Orta along with his wife, began a non-profit called In Triumph, where he began to take "unchosen" young adults off the streets and into his home. Out of his past, Pete says he is "able to relate to the young people in his program, young people who in their few short years have experienced prostitution, drug addiction, imprisonment and all manners of abuse and rejection". Now, when given the opportunity to address an audience about his journey, Pete loves helping people understand the blessing of taking on the suffering and burdens of those who could never return the favor. The young people he calls "unchosen" are a nameless and growing group in our country and Pete loves the opportunity to introduce his audience to the third world here in America.
