ProgressNow Colorado, the state's largest nonprofit progressive advocacy organization, announced Monday that Executive Director Ian Silverii will step down sometime in the coming months. "It's time for me to step out of the spotlight" and let someone from the progressive community step in, he said. "It's been fun to be the tip of the spear for the professional left," Silverii told Colorado Politics Monday. Silverri joined ProgressNow as executive director in June, 2016. ProgressNow, which was founded in Colorado by Michael Huttner, has affiliates in 23 states. âSince our founding all the way back in 2003, ProgressNow Colorado has played a central role in the evolution of this state not just from red to blue, but into an example of a cohesive and functional progressive movement that achieves tangible, long term results,â Silverii said in a ProgressNow statement Monday. âOver the last four and a half years, Iâm proud to have assembled a team of some of the best digital organizing, video production, and political communications professionals to be found anywhere in the commercial or nonprofit sectors."
