Well, this is a bummer. Dave Spigelmyer, someone we consider to be a friend, is retiring from the Marcellus Shale Coalition (MSC) effective today. He will be replaced by MSC board member Dave Callahan, who officially takes over on Monday. Spigelmyer has been president (the second president of the MSC) since 2013. He took over from another terrific person, Katie Klaber, the organization’s first president. Dave Callahan has big shoes to fill, but we’re confident he’s up to the task.
