Staff & leaders

Dr. Brian MacArthur
Interim Senior Pastor

Dr. Brian MacArthur became Interim Senior Pastor at BSBC on September 1, 2017 and has committed to serve in this position half-time for up to one year. He retired from full-time ministry on June 30, 2017 after serving for over forty years as an ordained minister. For most of his ministry he pastored churches within Nova Scotia and New Brunswick, plus served for 11 years as President of Crandall University in Moncton, NB. Pastor Brian and his wife, Rossanne have five grown children and 12 grandchildren.



Rev. Greg Geldart
Interim Associate Pastor to the Traditional Congregation, Children and Adult Ministries

Greg joined the pastoral staff at Brunswick Street Baptist Church in September of 2002. A native of Moncton, NB, he received his post-secondary education at Atlantic Baptist College (now Crandall University) in Moncton and at Southern Baptist Theological Seminary in Louisville, Kentucky. As of January 2018, Greg serves BSBC as the Interim Associate Pastor to the Traditional Congregation, Children and Adult Ministries — a long way of saying he has diverse areas of concentration in the interim period as we wait for a new Senior Pastor. Greg has a passion for enlivened traditional worship that engages the heart, mind and soul and uses his musical gifts in planning these services and directing BSBC’s Adult Sanctuary Choir. He works with the Music Team to support the ministry of other choral and instrumental musical groups in the church. Greg provides ministries and programs for children and adults and values opportunities to engage in pastoral care for all ages. Greg loves to laugh and enjoys the liveliness and spiritual vigor of BSBC. He is married to Margaret and they have a daughter, Claire.

Pastor Steve Patterson
Interim Associate Pastor to the Contemporary Congregation and Ministry to Senior Adults

As of January 1, 2018 Pastor Steve joins the pastoral staff full time as Interim Associate Pastor to the Contemporary Congregation and Ministry to Senior Adults. While this may seem like an interesting mix, it builds on his ministry these past years first as Contemporary Worship Coordinator and then, in 2017, in an expanded part time capacity as pastoral visitor to many of BSBC’s shut-in members. In his new capacity, Steve will continue to plan, coordinate and lead the contemporary worship services as well as connecting with those who attend this service outside of Sunday mornings. He will continue to provide church services at various retirement homes and bring the gospel message accompanied with his guitar to play familiar hymns as well as newer worship songs during his visits. He has discovered that building personal relationships with seniors who are no longer able to get to church is not only important but is also a joy and privilege for him. Steve preaches whenever called upon, and embraces the process of searching into God’s Word to continually learn more about our infinite and awesome God! Now as a full time pastor, Steve will be available to minister to the full congregation of BSBC providing pastoral care and support. With a Masters in Pastoral Ministry degree in hand, he has just completed studies toward a Masters level Graduate Diploma at Acadia Divinity College. As he journeys toward ordination, Steve appreciates the continued support of his wife, Cindy and their three children — Taylor, Lauren and Brady.
