Peavy practiced law in Fort Worth, Texas for over 12 years before relocating to California where he pastored a church in Los Angeles while pursuing doctoral studies at Claremont Graduate University. He later gave up pastoring to focus on teaching and writing. He now teaches at the University of Phoenix and Victor Valley College as well as Canyon College.

Without a doubt, Peavy's speaking and writing reflect the many influences on his life's journey: law, theology, philosophy, and practical experience. Buddha and Jesus play major roles in the shaping of Peavy's religious views whereas Existentialism mostly informs his philosophical ideas.
