Jason Thiellen

“It’s important to me that what I’m doing is driving the company forward.”

Jason brings over two decades of leadership, experience, and passion for land development to his role as CEO of E&A. Since joining the company in 2006, Jason has played an integral role in shaping the firm’s growth, culture, and reputation throughout the region.

As CEO, Jason oversees the company’s strategic direction while continuing to champion the planning, landscape architecture, and entitlement processes that have become a cornerstone of E&A’s integrated approach. Early in his leadership career, he combined these disciplines into a unified department, creating streamlined procedures that improved communication, coordination, and project delivery across the organization. His vision helped position E&A as a trusted resource for developers, real estate professionals, architects, title companies, attorneys, and municipalities alike.

Jason joined the Executive Management Team in 2011, was elected Secretary of the Board in 2014, and was named CEO in 2017. Throughout his career, he has remained deeply involved in every stage of the land development process — from concept planning, feasibility studies, and acquisitions to platting, entitlements, engineering coordination, construction, and final sales execution. His broad industry knowledge allows him to guide projects from a high-level strategic perspective while maintaining attention to the details that drive successful outcomes.

Known for his collaborative leadership style and solutions-oriented mindset, Jason is passionate about creating developments that positively impact communities and deliver long-term value for clients. He believes successful projects begin with thoughtful planning, strong relationships, and a deep understanding of the full development process from start to finish.

“I want to look back on my career and feel a sense of accomplishment. I want to be able to point to something and say, ‘I was a part of that.’”
