The First Baptist Church of Westwood has hired an old friend to serve as interim pastor following the retirement of the Reverend Sheldon C. Keller in January. The Reverend George H. Sinclair Jr. will take over while the congregation conducts its formal search for a permanent leader. Sinclair was the church’s interim pastor in 2006 and 2007. A Brooklyn native, Sinclair has served churches in Connecticut, Michigan, and Massachusetts, where he has stepped in as a part-time interim pastor at more than 20 houses of worship. He began his duties locally on Feb. 17, according to the church’s website.
