For those who may not know the history of MH Ballard in 2012 Scott Harris took over when Alex Early left after being lead pastor at Ballard for just a few months in the wake of Bill Clem's resignation. More recently at Mars Hill Ballard Nathan Burke departed in August 2013. That resignation may or may not have gotten announced by Scott Harris but Nathan Burke was replaced by Adam Christiansen from the look of things.
Ballard has had some impressive turnover in 2013 since Bill Clem left. Not quite as impressive as no less than three pastors at Mars Hill Downtown all resigning for various reasons within the same month but let's let Event Horizon explain that stuff in more detail since the blogger at Event Horizon appears to have actually been at the meeting in which Tim Gaydos' resignation was announced. It may be advisable to take some of the statements with a grain of salt as one should for things reported.
In any event, Krombein has been announced as on his way out.
