The Rooftop International Operations Team

Rev Dennis Pethers is the Founder and International Pioneer of the Rooftop Ministries.
Born and brought up just on the edge of London, England, Dennis is from a background where church did not feature at all. As he puts it: “I didn’t know that I didn’t go to church—and I didn’t know that I didn’t know Jesus”!
Dennis became a Christian at the age of 19 while reading the book Mere Christianity by C.S.Lewis. This life-changing encounter with God filled his life with a new passion and from that day he wanted everybody to hear the amazing news about who Jesus is and what He has done for them.

Since deciding to follow Jesus, Dennis trained for ministry at Spurgeon’s college, pastored a church, worked in regional ministry and national ministry then, for 20 years he led Viz-A-Viz Ministries, an organization consisting of evangelists, a rock band, theatre companies and a video production team that produced videos that have been used in evangelism in many parts of the world.
In 2014, Dennis began The Rooftop Ministries and now travels the world communicating the vision of The Rooftop GLOBAL ENCOUNTER and inspiring and equipping the church worldwide to Join Jesus in His Mission.
Dennis is the author of a number of books and evangelistic materials for all ages as well as a discipleship coach and inspirational public speaker.

Marion Spencer joined the Rooftop team in 2016 as a member of the International Council. Currently serving as International Director of Ministry, Marion works closely with Dennis Pethers in the day-to-day operations of the ministry.
Marion’s heart has always been to serve others. Starting a relationship with Jesus Christ as a teenager, Marion expressed his desire to serve others through careers in law enforcement and as a paramedic for over twenty-five years.
Feeling a call from the Lord to ministry, Marion has served God’s people in a variety of roles including youth pastor, associate pastor, senior pastor and missionary to Asia and Ukraine. Marion is a strong advocate for mentoring relationships in the church. He credits a dear friend for greatly helping him on the path to Christian maturity and ministry through close discipleship and providing a living example of what it means to serve Jesus Christ.

Currently residing in Nashville, Tennessee, Marion and his wife, Vicki, are active members of their local church. In addition, Marion pastors a home-based church fellowship and the two minister together at a local shelter for women and children in Nashville. Both Marion and his wife plan to retire in 2020 looking forward to more time to focus on ministry opportunities.

David Fernández is a lawyer, theologian, bilingual journalist, and businessman. Since the beginning of his international travels in 1994, he has been dedicated to the investigation and study of various topics of importance in global geopolitics and the Bible. Passionate about teaching, he shares his knowledge as a speaker and author.

David joined The Rooftop in 2023 as the COO, overseeing operations internationally. With his skills, he likes to serve and improve other people’s lives, especially with the knowledge of God and His salvation through the Lord Jesus. He currently lives in Bogota, Colombia.

Dave started life on the family farm milking cows and driving tractors, but God had a different plan for his life. While studying for a theology degree at Bible College he became interested in communicating the Gospel of Jesus through visual media. Ever since then, Dave has been working with a number of different Christian organisations; using video production, graphic design, social media, and other tools, to tell others about the Christian faith. He lives in Essex, UK with his wife and three children.

Dave has joined the International Operations Team to use his skills and expertise to further expand the reach The Rooftop Ministries. In the build-up to the Global Encounters, he will be communicating the amazing work that is being done by our Pioneers around the world, as we work towards making a million disciples in 100 countries.

Victoria “Vicki” Spencer joined The Rooftop International team in 2018. Vicki, wife of International Director of Ministry Marion Spencer, serves on the International Operations Team providing accounting and support services for the organization’s extensive ministry network. This includes Rooftop Pioneers who represent The Rooftop International in each country where the ministry operates. Both Vicki and her husband are active in day-to-day operations.

Vicki says, “I find peace and joy in serving others, so that’s what I do.” In her professional life, she has always worked in some aspect of customer service even to this day. In her personal life, Vicki enjoys blessing cancer and other special needs patients with hand-sewn and crocheted gifts designed to bring a ray of joy into often gloomy circumstances. She also serves with her husband in ministering at a local shelter for women and children in Nashville, Tennessee, and joyfully opens her home to host a local home-based church fellowship. Many who have been blessed by Vicki’s ministry through the years note that her warm and uniquely personal approach richly demonstrates the love and message of Jesus Christ.
