Coalition Staff Members

Christine Mahler


Executive Director

Originally from Missoula, Montana, Christine relocated to the Seattle area after almost a decade working in fundraising and nonprofit leadership in the “other” Washington. She started at the Coalition as the Director of Philanthropy and was appointed to the role of Executive Director in February 2018.

Christine has led fundraising efforts for causes ranging from international affairs to money-in-politics reform, with a special emphasis on relationship management and working with broad ranging coalitions and boards.

Christine grew up loving the outdoors. As a child, you could usually find her outside, whether that was playing competitive soccer throughout the Northwest; hiking, camping, and horseback riding in Montana’s wilderness; floating the Blackfoot on rafts and tubes; helping her mom in the garden; or just playing in the yard or the neighborhood parks. Today, she is passionate about ensuring all Washingtonians are able to experience similar wonders, whether that’s nurturing a garden P-Patch, walking your dog in the park, or backpacking in the backcountry.

In her free time, Christine enjoys gardening, reading, cooking & baking (especially sourdough), watching soccer (she’s an unapologetic DC United supporter!), and exploring all that the Pacific Northwest has to offer, hiking and running with her dogs, Nitro and Tahoma, by her side.
