Pastors

Derek Overstreet
After spending ten years in the Real Estate/Mortgage profession in the Phoenix area, Derek and his family left it all behind to study at the Sovereign Grace Ministries Pastors College in Gaithersburg, Maryland. After graduating from the Pastors College in 2004 and a short internship in our Phoenix church, Derek relocated to Tucson in 2005 to serve Sovereign Grace Church. Derek now serves as the senior pastor at Sovereign Grace Church and has the privilege of carrying the primary responsibilities of preaching, leadership, and overall vision for the church. Derek and his wife Donna live in Northwest Tucson with their three children Desirae, Brett, and Tyler.

Tim Lambros
Leading a team of 50 people, Tim started Sovereign Grace Church in April, 2000. Prior to that he had a successful 17-year career in the insurance industry and was active in Arizona politics. But God showed Tim that, while good laws and insurance policies have their place, he was called to offer people a higher and better hope for safety and security—the person and work of Jesus Christ.

So, as a member of Sovereign Grace Church in Gilbert, Arizona, Tim spent two years being trained by the pastoral staff and attended the Pastors College of Sovereign
Grace Ministries in Gaithersburg, Maryland, in 1998 and 1999.

Tim and his wife, Kathy, have been married for 30 years. They have two married daughters, a daughter and son living at home, and an increasing number of grandchildren.
