I joined The Westerlund Team in 2025, bringing a strong background in leadership, relationship-building, and financial expertise. Before transitioning into real estate, I held various roles within Florida Gulf Coast University’s Athletics Department, including serving as Interim Athletics Director in 2024. My experience in fundraising—built on trust, communication, and professionalism—naturally aligns with my commitment to delivering exceptional service in real estate.

Before moving to Southwest Florida, I spent a decade in Madison, Wisconsin, working in finance while maintaining a mortgage origination license. I was also actively involved with the University of Wisconsin’s athletics department, assisting with event management, game-day operations, and fundraising efforts through the UW Foundation.

Originally from Madison, I earned my finance degree from the University of Wisconsin-Whitewater, where I captained the men’s basketball team and competed in the NCAA Division III Tournament. Today, I call Bonita Bay home, living in Bonita Springs with my wife, Kelsey—a former FGCU women’s basketball player—and our rescue dog, Captain.

I approach each transaction with care, transparency, and a relationship-first mindset, ensuring buyers and sellers feel confident and supported every step of the way. My goal is to make the process seamless, helping you achieve your real estate dreams with trust and expertise.
