Who We Are

The purpose of Beacon Int’l Baptist Mission (BIBM) is to serve local churches and their missionaries as they endeavor to fulfill the Great Commission.
Founded by Dr. Jerry Mullendore in 1995 as Evangelization in Eastern Europe (EEE) and expanded in 2006 to serve missionaries world-wide, BIBM is now led by missionary Adam Crabtree. It continues to work in the Balkans and in many other fields across the globe.
BIBM does not replace the role of the sending church or the sending pastor. The sending church has the only authority to ordain, commission, guide, and discipline. BIBM simply exists to serve both the sending church and their missionaries.
Whether a missionary requirement calls for processing financial support, arranging a missions trip, constructing or renovating facilities, organizing youth camps, hosting Bible conferences or institutes, or providing ongoing missionary care, BIBM stands ready to offer assistance.

Connecting Those Who Give With Those Who Go

In today’s hectic environment, pastors often struggle to maintain a sufficient framework of fiscal and ministerial accountability with their missionaries who are stationed abroad. Keeping abreast of the affairs of local governments overseas presents an even greater challenge.

BIBM functions as the crucial LINK that connects the sending church, the missionary family, and their supporting churches, particularly offering invaluable assistance during times of turbulence.
When a missionary family and their local church partner with BIBM, they are adequately equipped for deputation, relocation to their mission field, language study, cultural adaptation, evangelism, discipleship, church planting, and training the next generation for ministry, so the work continues in perpetuity. Furthermore, our office assits with every aspect of a productive furlough.

BIBM operates under the authority of Eastside Baptist Church, located in Greeneville, Tennessee. The Crabtree family belongs to this flourishing, growing church. Pastor David Fox has served as senior pastor of this wonderful congregation since June 2001. For more information about Eastside Baptist Church, please visit: www.EastSideBaptist.info.


Founded upon the biblical paradigm of missions, BIBM furnishes the necessary support for each missionary family, pastor, and church to maintain communication and responsibility.
  1. Financial: The location of BIBM’s office is in Johnson City, Tennessee. The Mullendore Missions Headquarters offers substantial advantages to the sending church, supporting church, and missionary family. BIBM maintains a comprehensive system for monitoring monthly financial contributions, furnishing monthly financial statements of giving, reimbursing missionary expenses during fieldwork or deputation, and transferring funds to missionaries for living and project-related purposes. This is accomplished while maintaining accurate financial records in order to report all missionary earnings to the IRS and pay taxes for the missionary family. BIBM maximizes the potential for the missionary and the church to exercise judicious stewardship over the provision of the Lord.
  2. Ministry: Missionary Adam Crabtree, who serves as the Executive Director of BIBM, ensures uninterrupted communication with the missionary families. His vision is for each pastor to participate in his missionary’s church planting efforts and for the missionary’s fruit to be shared with the sending church. BIBM does not substitute for the authority of the sending church or the responsibility of the sending pastor. The authority to decide on all aspects of ministry, such as discipline and direction, is vested in the local church. The director has the capacity to provide assistance to both the pastor and the missionary. His years of domestic and international experience make him a valuable asset. BIBM retains the prerogative to sever fellowship with a missionary who violates ministry policies and procedures or doctrinally diverges from the organization.
  3. Government: BIBM alleviates the local church of its financial burden. The office staff ensures that the allocated funds are held accountable. BIBM remains updated on local news from around the world in order to serve the missionary family more effectively. Amidst periods of instability, the director and his family served in Greece; therefore, he is cognizant of the critical nature of maintaining communication in such circumstances. Ensuring safety is the foremost consideration in BIBM. Wire transfers, exchange rates, residency/missionary visas, missions trips, furloughs, and the shipment of ministry supplies are all potential sources of complications. With its vast expertise and experience, the BIBM office is able to provide assistance to every missionary family, irrespective of their specific area of service.



Brief History (1995-Present)

Dr. Jerry Mullendore founded Evangelization in Eastern Europe in 1995. EEE functioned as a mission organization whose exclusive focus was on the Eastern European Balkan countries. God bestowed numerous blessings on EEE. Families of missionaries were dispatched to Albania, Macedonia, Romania, and Greece. Dr. Mullendore successfully obtained an open-ended registration for the Macedonian ministry, which remains valid for entry into the country at present. Despite the passage of time, this well-established mission work continues to function under the guidance of a national family based in North Macedonia. We are ecstatic to see how God’s hand remains on that ministry.

As more missionaries partnered with EEE and the mission expanded, the church office could no longer accommodate everything required for the daily operations of the organization. Spring 2002 marked the ministry’s authorization to acquire a building situated in Johnson City, Tennessee, through the grace of the Lord. After the purchase was finalized, renovations commenced without delay. Converting an abandoned gas station and convenience store into a functional mission office required considerable effort. The official dedication of the structure occurred in July 2003. The new office building featured three offices, a large conference room, an abundance of storage space, and a two-bedroom apartment. This is an extraordinary gift from God.

The Advisory Council voted unanimously in 2006, under the direction of Dr. Mullendore, to expand the ministry of EEE to include missionaries called to serve beyond Eastern Europe. This growth necessitated a name change. At that time, the organization known as Evangelization in Eastern Europe was renamed Beacon International Baptist Mission. BIBM continues to be showered with God’s grace. BIBM has witnessed significant international expansion beyond Eastern Europe.

In November 2016, the Lord called Dr. Mullendore home. As of January 2017, missionary Adam Crabtree assumed the role of Executive Director, succeeding the late Dr. Mullendore. The BIBM missionary family continues to expand globally under his direction.

In commemoration of the endeavors and selflessness of Dr. Jerry and Christine Mullendore, the mission office was formally named the “Mullendore Missions Headquarters” in July 2018, marking the 15th anniversary of the initial building dedication.
