Commercial Real Estate Austin, TX

Doug has a deep understanding and unmatched market knowledge of the entire Austin commercial real estate landscape with a primary focus on office tenant representation & site selection.  Since 2006, he has built a substantial client base through hard work, client retention, partner referrals, and long-term relationships. Never deviating from his original business plan based on strategic consulting for early-stage companies and maintaining long-term partnerships. Doug has completed over 450+ transactions totaling well over 5M SF of space over the last 15 years. 

Doug's entrepreneurial clients played a significant role in his decision to become one himself by bringing Colliers back to Austin in 2014 as an affiliate office. He and his two partners grew the office from three (3) people in an executive suite to fifteen (15) by 2019 and selling the affiliate office to corporate Colliers in  January 2020.  We are excited to keep growing our team, customers, and service lines in the coming years as Austin continues to become one of the primary growth markets in the entire country.  

In a career spent serving my clients now spanning more than 30 years I have represented some of Austin’s largest and most financially complex transactions for companies such as IBM, Motorola, Charles Schwab, and Q2ebanking. I pride myself on the “service first” relationship with my clients. Valued by my clients, not as a transaction manager, but as a real estate consultant that is integrated into the fabric of the organization. Much of my career was spent at CBRE leading their number one tenant representation group. In 2006 I was offered the opportunity to become an owner and manage a boutique brokerage firm, HPI Corporate Services. Despite its small size, it became one of the most successful brokerage firms in Austin including having the number 1 and 3 brokers as ranked by the ABJ in 2011. In 2014 the opportunity to become a principal and Co-managing partner for Colliers Austin with all of its resources was too much to pass up. Since opening the office in Austin it has become the fastest growing brokerage company in the city. In 2014 and 2015, I was a Colliers' Everest Award recipient. This award is bestowed upon the top 10% of all Colliers professionals in brokerage, valuation and corporate solutions across the U.S. business based on revenue production.
