The Natural Step Network USA Staff and Associates
Regina Hauser, Executive DirectorRegina Hauser - Executive Director
Regina believes that life is an adventure that shouldn’t be missed, which goes a long way to explain her decision to leave the comfortable life of a lawyer at Schwabe Williamson and Wyatt to take the helm of The Natural Step Network. Because she enjoys blazing a trail, it makes sense that she has led the Network from a local organization to a growing national network in just seven years. Perhaps it was the patent litigation in her background that attracted her to the science of the Natural Step. Regina’s exuberance for life, her sense of humor, and her passion for sustainability can be seen both in her many presentations about the Natural Step, and slide shows from trekking adventures in places like Bhutan, Tibet and Peru. Her husband Chris will attest that she’s not afraid to take a spill, whether in water, mud or life. Regina sees the challenge of sustainability as a defining opportunity for individuals and organizations alike, and believes our response to that challenge will define our character for generations to come.

April Knudsen, Office AdministratorApril Knudsen - Project Manager
After earning an English degree from Centre College, April began a diverse career in administrative support and event planning. Always true to her skill set, this California native has lived and worked in Texas, Indiana, New Jersey, Kentucky and Colorado, and most recently spent five years in Nome, Alaska, in the field of healthcare administration. April came to The Natural Step Network in 2007 as an office administrator, and quickly took up additional duties in membership, communcations and IT. An amateur interest in architecture and design led to her initial investigation into sustainability as a career path, and she's grateful and excited that her work with The Natural Step has allowed her to work with so many leading figures in green building today. She lives in Portland with her husband, and dreams of living abroad someday. Contact April.
