Rev Roger Collins met the Lord Jesus for himself in the early 1980’s and stepped in as a pastor for the first time in 1985. Since then, he has devoted his energy to telling people the good news of the Gospel - Jesus Christ in them, the Hope of Glory.
Roger has held numerous tent campaigns across the United States as well as in South Africa. He has traveled to South America, Southern Africa and Western Africa to encourage people in the Lord. He has also helped start numerous churches and other outreach work in the US.
He is the founder of Roger C Collins Ministries Inc, an independent ministry under the direct headship of our Lord Jesus Christ. Open Door Tabernacle is the local church in Tucson, AZ that operates under the umbrella of the ministry.

Rev Nicholas Cowie is the Assistant Pastor. He is a husband, father, and grandfather. His desire, both for himself and for others, is that people would see Christ for themselves, trust in Him for all things, and follow Him through every circumstance. He encourages others to submit to Christ, walk where He leads, and grow in His grace and love. Above all, Nicholas wants people to know Christ personally, because our God and our relationship with Him are deeply personal.
Through his own life, Nicholas has come to understand that there is truly no life apart from Christ, and that anything apart from Him simply is not worth pursuing. He believes that God has called him to preach, and his desire is to yield to that calling and be used by the Lord for His glory. His prayer is to see God’s grace, mercy and love at work both in his own life and in the lives of others.

Rev Michael Rojas is a local minister who was raised in a Christian household. He is the son to a missionary preacher that preached in Central America and northern parts of South America. Michael has seen God in his life many times and mostly in his family and has witnessed the change God has made in each member of his family. He has seen the mercy and love that God has for all that seek to follow him.
Michael became a minister to answer a calling in obedience to the Lord and to share the Word with all of those that God calls upon.
