Founded in 1975 as a small, family-owned paving company, Keeley Construction has grown into a regional leader with a strong commitment to sustainability. Today, their efforts go far beyond building projects — they’re fostering a culture of environmental responsibility among employees and the community.
Keeley’s core values of responsibility, adaptability, innovation, stewardship and environmental care are brought to life through initiatives that engage team members directly. From planting trees to exploring emerging green trends, Keeley turns sustainability from a concept into a shared mission. A major driver of this progress is Keeley’s Green Team, which was created to spark conversation and action around energy efficiency and waste reduction. As a participant in the 2024 St. Louis Green Business Challenge at the Leader Level, the company hosted four sustainability-focused learning sessions for employees, including Geeking Out on Trees with Forest ReLEAF, Bringing High-Performance Building Envelopes Home led by Keeley VP Matt Muller and Director of Design Derek Maschek, Intro to the WELL Building Standard presented by Keeley staff, and Minding the Gaps: A Tech Review of High-Performance Building Envelopes with GRW Engineering.
Beyond attending sustainability sessions in the workplace, Keeley employees extended their commitment to the community by planting trees at North Springs Head Start Center, an effort that underscored the company’s zero-carbon goal and helped contribute to cleaner air quality in the region.
“In 2024, the Green Business Challenge has provided Keeley Construction with valuable insights into adopting a more sustainable approach to operations and project execution,” said Casey Delaney, Director of Business Development for Keeley Construction. “Keeley is excited to continue making progress toward reducing waste and energy consumption in 2025 and beyond.”
The 2024 challenge year also marked the official launch of Keeley Green as the seventh cultural pillar of Keeley Companies. This initiative equipped employees with tools and resources to grow personally and professionally while advancing sustainability. Keeley’s progress was also made evident on its website, having highlighted energy-efficient commercial buildings, renewable energy facilities and transmission systems powering the clean energy grid. Photos showcase how Keeley blended passion and productivity to create a cleaner planet — living proof of their values in action.
