He has preached at large evangelistic campaigns, taught at CfaN Fire Conferences, ministered in churches worldwide, and established ministries under the leadership of Evangelist Bonnke.

Pastor Tomazsewski was born in Germany and held various management roles in the commercial sector before pursuing full-time ministry.

He was chairman of the PEC 2003 (Berlin/Germany), hosted by the PEF and other ministries, and served many years as treasurer on the board of the Pentecostal European Fellowship (PEF). In 2012, he founded the ministry “Calling Ministry” in response to God’s call to preach, teach, and serve, with a focus on Europe and North Africa, resulting in many salvations and healing testimonies. Calling Ministry is a member of the World Evangelical Alliance and the African Pentecostal Mission, with offices in the US, Germany, Liberia, and South Africa.

Siegfried has led over 120,000 people to Christ through mass evangelism and one-on-one witnessing, preaching, and sharing, with healings often following. His passion is to lead people to the cross of Christ and impart the fire of God that burns in him.

As an executive member of the Global Evangelist Alliance (GEA) and CEO of 1GDA, he oversees and directs the African operation in partnership with ministries worldwide for MM33.
