Jim Tolstrup
Executive Director
Jim Tolstrup is the Executive Director of the High Plains Environmental Center in Loveland, CO, a unique model for preserving native biodiversity in the midst of development. His past work experience includes serving as Land Stewardship Director of Shambhala Mountain Center in Red Feather Lakes, CO and running his own landscape design business in Kennebunkport, Maine where he installed gardens at George and Barbara Bush’s “Summer White House.”
Jim holds a Certificate in Gardening Arts from the Landscape Institute of Harvard University and the Arnold Arboretum, he has written numerous articles on gardening and environmental stewardship for various publications, and is a past recipient of Denver Water’s Xeriscape Award, ALCC’s Excellence in Landscaping Merit Award, ASLA Land Stewardship Award and the Sustainable Living Association’s Sustainable Contribution Award.
Growing up in an urban environment near Boston, MA, Jim had to “look hard to find nature.” This background has led to a strong sense of empathy for people, and children in particular, who don’t have access to the restorative qualities of nature in their daily lives.
Jim is personally committed to bringing together people with diverse points of view (environmentalists, business people, and other community members) in an inclusive dialogue about preserving the natural world for future generations.
As a founder and former president of Cankatola Tiospaye, a non-profit that provides material assistance to Native American Elders, Jim has gained a perspective through life-long friendships with Native Americans living on reservations in South Dakota and elsewhere, that the land we live on is much more than a commodity, it is a community of which mankind is an integral part.
Stephen Hornbeck

Stephen is the Nursery Manager at HPEC. Born in Kentucky, Stephen entered the field of ecology with watershed and riparian restoration work up and down the Appalachian Mountain corridor. During stream mapping, fish tissue collection, and habitat assessment inventories, he fell in love with the variation of regional flora adaptations. After moving to Colorado in 2018, he began studying evolutionary biology while learning the plant communities of the plains and foothills. In his free time, he enjoys growing native plants for his garden, spending time with his daughter, and playing banjo.

Breyer Kinzer
Outreach & Education Manager
Breyer Kinzer is the Outreach & Education Manager at HPEC. Before coming to HPEC she worked as a Larimer County Park Ranger and Rugged Research Lead Environmental Educator.
Breyer was born and raised in Oglesby, Illinois where he she fell in love with the rivers and forests around Starved Rock and Matthiessen State Parks. The oldest of 4 siblings, she spent her summers kayaking the river and catching fireflies in corn fields with her brothers and sister.
Loving nature came easy, but learning about it was tough. Public school offered only agriculture in the way of environmental science, if anything at all. Breyer followed her passion and taught herself most of what she knows from books and YouTube videos. After completing two Associate’s degrees at Illinois Valley Community College, she moved to Colorado in 2020 to be amongst environmentalists.
She has a passion for education and is happiest when she is working with children. She enjoys the gym, reading, cozy video games, and traveling with her high school sweetheart.

Greg George
HPEC Board Chair, Executive Committee
Expertise: Special Projects Manager, City of Loveland, Retired
Throughout my 50-year professional career as an environmental planner, I’ve worked for city, county and regional governments in the United States and New Zealand. My commitment has been to persuade decision-makers to acknowledge the importance of preserving the natural environment.
From 1971 to 1990, I worked for the Tahoe Regional Planning Agency (TRPA), a bi-state agency comprising California and Nevada. Its primary responsibility was to regulate all development activities within the Lake Tahoe watershed, with the overarching objective of safeguarding and enhancing the water quality of Lake Tahoe. TRPA regulations hold precedence over all local authorities, including four counties and one city, in the approval of all development proposals. As Chief of the Development Review Division and later as Principle Planner in the Long Range Planning Division, I had a significant role in achieving the goals of the TRPA.
For the next five years, I served as the Comprehensive Plan Administrator for Pima County, Arizona. During this time, I spearheaded an extensive stakeholder outreach effort to develop a new Comprehensive Plan for the county. The primary objective of the plan was to curb the expansion of urban development around Tucson and safeguard the unique environment of the Sonoran Desert. The Comprehensive Plan was unanimously adopted in 1995.
In 1995, I had the opportunity of relocating to New Zealand. At that time, New Zealand had recently enacted a new natural resources management act that emphasized and reinforced its “clean and green” policies. As the Manager of the development Review Section at Waitakere City, I witnessed a nationwide commitment from decision-makers and Kiwis alike to prioritize the remarkable natural environment of New Zealand.
In 1997, I joined the City of Loveland, Colorado, and spent 22 years in the Development Services Department. During my tenure, I held the positions of Current Planning Manager for 10 years and Director of the Development Service Department for another 10 years. In my final two years as Special Project Manager, I led a comprehensive stakeholder outreach initiative to develop a Unified Development Code. This new code consolidated the subdivision, zoning, and annexation codes and updated development standards to align with the latest trends in urban development. The Planning Commission unanimously recommended its approval, which was subsequently approved by the City Council in 2021.
