Greg was born and raised in Fishkill, New York where he wrestled and played baseball. Shortly after arriving on campus at ASU, Greg believed in Jesus Christ for eternal life through the ministry of Campus Crusade for Christ (a.k.a. – Cru). Greg immensely enjoyed the challenges of living out the Christian life while at ASU and was moved to join the staff of Crusade upon graduation. While raising financial support, Greg felt the desire to enhance his biblical studies, so he left Crusade staff and enrolled in seminary.
During his years at Phoenix Seminary, Greg met his wife, Leigh Ann. They married in ’96 and have three children.
After graduating from seminary, Greg served in a number of ministry positions including: church planter, worship leader, teaching pastor, and associate pastor.
Greg joined the Valley Christian staff in 2008 as co-chair of the Bible department and Bible teacher. He immediately fell in love with teaching the Bible in an academic setting, all the while ministering to the next generation of believers.
In 2010, Greg’s family was devastated when Leigh Ann was innocently killed in a car accident coming home from work. She was 35 yrs old. Greg and his three children (10, 6, 4 yrs old) dealt with their tremendous loss in part through aide of family, friends, and the Valley Christian community.
In 2012, God graciously allowed Greg to meet another wonderful woman, and he is again happily married. Together, Greg and Jennifer are trying their best to raise five children!
When he’s not researching or writing, Greg can be found teaching The Mine at Cornerstone, playing golf, or drinking a good pour-over from Cartel or Bergies. Avid Pittsburgh Steelers fans, the Tonkinson family recently got a black German Shepherd/Lab puppy and affectionately named him Steeler.
