About
Over 25+ years, I have come to learn that the best commercial real estate decisions are made by people who understand their market, know what's at stake, and have the clarity to act with confidence. I am based in Madison, Wisconsin and have over 25 years of experience, representing clients in the successful completion of over 600 sale, lease and consulting transactions since 2005.
My work with industrial, office, and land spans Dane County and the surrounding region. Clients rely on me for real-time market insight, grounded advice, and strong execution. In 2025, 68% of my work came from repeat clients and referrals; a testament to the trust I’ve earned helping leaders make critical real estate decisions.
My work has delivered results for clients like Mustang Properties, Weir Minerals, Riddell Sports Group, and Object Pharma. Whether driving a high-speed lease-up or targeting the right buyer with precision outreach, I help clients capitalize on opportunities when they arise. I’ve been named a CoStar Power Broker nearly every year since 2013 and have received 14 “Deal of the Year” awards from the Commercial Brokers Group of Madison.
