Logan Simpson is proud to have an Inclusive Impact Charitable Donation Program, where employees vote on various organizations to support throughout the year, combining a firm donation with an employee match to maximize our impact.

This time, our staff voted to donate to DigDeep!

Changes are coming for historic preservation in America. In July 2026, the Advisory Council on Historic Preservation introduced sweeping changes to the federal regulations that have balanced historic preservation with development for over 60 years. Logan Simpson Principal Tina Hart, as President of the Utah Professional Archaeological Council, sat down with Mike Anderson from KSL to discuss how this could affect all Americans.

🦇 Happy International Bat Night 2026! 🦇
Na na na na na na na na... it's that time of year again. Tonight, we're celebrating the most misunderstood mammal on the planet and the biologists working to protect them.

This year, a team of Logan Simpson biologists is expanding what's possible for bat work at the firm. Funded by the Logan Simpson’s internal grant program Denali Trek, Kaidence McCarthy, Angela Myszynski, and Matt Lau are building in-house capability to process and interpret bat acoustic data, completing training through Vesper Bat Echolocation Services, developing hands-on proficiency with the SonoBat analysis software, and pursuing more bat mitigation and acoustic survey projects. This growing expertise strengthens our ability to help clients identify protected bat species, safeguard roosting and foraging habitat, and inform sound mitigation strategies on projects across the region.

On International Bat Night, it's a good reminder of the role biologists play in both advancing the science and raising awareness that protects these species. Look up tonight, you might just spot one of these sky puppies flying by. 🌠🦇

Giving back to the places we live, work, and recreate. 🌿

Our Fort Collins team recently spent time on the trail volunteering along a local segment that Logan Simpson has adopted, helping with cleanup efforts and stewardship to keep these spaces accessible and enjoyable for the community.

Caring for the landscape goes beyond our projects. It’s part of who we are. ⛰️

Our Fort Collins design team had a blast serving as instructors at the Southwest Park and Recreation Training Institute Park Planning and Maintenance Academy, an intensive training program designed to help park professionals sharpen their skills and strengthen their organizations.
