Co-Lead Pastor at Westchester Details

When Pastor MacKinnon was called to be Senior Pastor in 2013, he indicated one of his long term goals was to seek out and mentor a younger man to eventually become the next Senior Pastor.  When Pastor Chuck Mullikin was called to Westchester in 2013 that process began on an informal basis.  During 2016 an Elder sub-committee met with Dave and Chuck to initiate a formal process that would accomplish that transition over the next two years.  At the annual meeting in January, 2017 it was announced that a short-term "Co-Pastoring Plan" had been developed and would be shared with the membership through a series of spring informational meetings.  Those meetings were held and in late May the Elders brought to the congregation the opportunity to formally vote to move forward with "Co-Pastoring" with an effective date of June, 1 2017.  An overwhelming majority approved the plan.  From June 1, 2017 to May 31, 2018 Pastors Dave and Chuck are Co-Lead Pastors at which time there will be a formal vote of the membership to call Chuck as Senior Pastor.  This is a unique opportunity that allows Pastor Chuck to transition from his previous position and responsibilities of Associate Pastor to eventually become the new Senior Pastor.  The final transition will be completed by September, 2018 when Chuck will be the Lead Pastor and Dave will return from a short sabbatical to serve in a yet to be determined capacity.
