Eileen Christensen

Principal

Eileen Christensen founded BEC Environmental, Inc. in 2002 to focus on addressing Brownfield Projects. She was fascinated by the opportunity to not only assess and clean up contaminated properties, but also to work with communities to transform those blighted properties into community assets. Eileen wanted to develop personal relationships within each community to better understand the unique needs and wants of the residents and leaders within that community. By obtaining a better understanding of the underlying drivers behind each project, she was able to help identify appropriate funding opportunities, technical assistance programs, and economic development diversification tools.
