As Director of the Natural Resources Department for the City of Fort Collins, Tom Shoemaker helped build early partnerships that shaped Larimer County’s open space conservation. Serving on the first Open Lands Advisory Board, he helped guide efforts that protected thousands of acres between Fort Collins and Loveland.

After retiring in 2008, Dave Marvin became a volunteer naturalist and photographer, leading hikes and capturing moments across Larimer County's open spaces. His dedication led to nine years on the Open Lands Advisory Board, culminating in his role as Board Chair.

Former biology teacher Jean Carpenter served six years on the Open Lands Advisory Board starting in 2000, helping rally community support for acquisitions like Hermit Park. She now serves as president of Friends of Larimer County Parks and Open Lands.

Since 2015, volunteer Herb Saperstone has led countless interpretive hikes across Larimer County's open spaces, creating 'aha' moments for visitors discovering the rich history and natural beauty beneath their feet—connections that keep people coming back.

After HPOS failed in 1994, Linda Stanley and Kelly Ohlson were part of the passionate core who regrouped, gathered thousands of signatures, and won in 1995—then again in 1999 and 2014. Four campaigns, two decades, one unstoppable partnership.

From those early bus trips in 1995 to 15 years on the Open Lands Advisory Board, Nancy Wallace witnessed HPOS transform from palpable excitement to protected reality: Long View Farm, Devil's Backbone, and the expansive Mountains to Plains vision.
