Adriana
As the Administrative Assistant to the President, Adrianna works closely alongside Brooks and Nina Buser to assist them in the ministry the Lord has given them. Throughout her college years and through the faithfulness of her brother, Adrianna learned the call from Scripture to be faithful in bringing the Gospel to unreached language groups. It was when her brother and his wife trained through Radius that she and her family learned the heartbeat of Radius and came to value this ministry. She and her husband, Manny, enjoy serving as members of their local church in San Diego, California. Though he doesn’t have an official role, he plays a humble and behind-the-scenes part in helping Adrianna fulfill her responsibilities at Radius.

Brad & Beth
Brad and Beth spent over 20 years planting a church among the Iteri people in Papua New Guinea. After the Iteri church could function on its own, they returned to San Diego where Brad was the Missions Pastor at Clairemont Emmanuel. In that role, he observed a disturbing increasing attrition rate among missionaries and, along with some other like-minded Pastors and others in the mission community, identified the need for quality cross-cultural training for missionary candidates. After years of research and prayer, RADIUS was born. Brad is the primary Church Planting instructor at RADIUS. He and Beth also travel extensively around the U.S. speaking at conferences and churches. Brad and Beth have 4 married children and enjoy spending as much time as possible with them and their 10 grandchildren.

Brooks & Nina
Brooks and Nina met at San Diego Christian College and upon graduation they married. Brooks worked in the field of accounting and eventually as a CFO of a Dutch multinational. Through their time in the word, and with the blessing of their local church, they eventually felt led to church planting among an unreached people group. In 2003, after 2 years of training, they, along with their 3-year-old son, left for the country of Papua New Guinea and lived among the Yembiyembi people. By God’s grace, they became fluent in the language of the Yembiyembi, developed an alphabet, taught the Yembiyembi to read and write in their own language, translated the scriptures, and saw the Yembiyembi church born and brought to maturity. In 2016, they returned to the U.S. where Brooks now serves as the President of Radius International and Nina is the Hospitality Coordinator. Brooks recently received an honorary Doctorate in Linguistics and Bible Translation from San Diego Christian College.
