Our projects range throughout the West, with some as far away as Alaska and Florida.

Logan Simpson is Moving Forward Under New Leadership

Logan Simpson’s leadership transitioned from founding principal Diane Simpson-Colebank to Bruce Meighen, AICP, on April 1, 2021. Bruce will lead the company on as the new president and CEO.

Internal ownership transitions are a rarity among small, privately owned planning and design firms, but for Logan Simpson’s leadership team, it was a must. “I didn’t want to just leave a legacy; I wanted it to be a living legacy that will continue the firm’s vision of guiding responsible change into the future,” said Diane Simpson-Colebank. “Our leadership team agreed and pulled together as a group to make it happen.”

Incoming president and CEO Bruce Meighen has been a part of Logan Simpson’s leadership team for nearly a decade and has 25 years of experience in community and environmental planning. “I feel privileged to lead a firm that has such a clear tradition of entrepreneurialism, innovation, and creativity,” he said. “I’m inspired that my fellow principals and shareholders have such confidence in the firm’s future and look forward to continuing to work with them to improve our communities and environment.”

Diane Simpson-Colebank will remain with the firm as a principal, focusing on key projects and clients. Check out our Executive Bios to learn more about Diane and other firm leaders—including principals Wayne Colebank, Jana McKenzie, Jeremy Call, Patricia McCabe, Erick Laurila, and Tina Hart.
