Professional Summary

Don MacWilliam has been a commercial real estate professional since 1986, specializing in industrial real estate sales and leasing in the Southwest Valley distribution market throughout his career.

Services include tenant representation and agency listings from many major developers, such as Merit Partners, ProLogis, EastGroup Properties, First Industrial Realty Trust, Sun State Builders, Exeter Properties, Sun Life Assurance, Majestic Development and CapRock Partners.

As an executive vice president with Colliers in Arizona, Don partners with Payson MacWillliam and Chris Reese. Their top-producing industrial team provides exceptional service and strategic solutions to its clients, representing both landlords and tenants.

Their diverse base of knowledge and expertise leads to successful and tailored real estate solutions. Don and Payson pride themselves on building relationships that continue far beyond a single successful transaction.

During the past decade, they have added more than 6 million square feet of user build-to-suits and more than 5 million square feet of speculative development product to the Southwest Valley distribution market. The team has also increased the total distribution base by almost 10 percent in the past 10 years.

Don is actively involved in his community and has focused his passion for baseball and his desire to give back in a specific way, spending a great deal of time raising funds to renovate the baseball field at a local high school.  He is actively involved with these organizations: Luke Air Force Base, Arcadia High School Dad's Club, Juvenile Diabetes Research Foundation, Andre House, St. Vincent de Paul, Westside Food Bank and Nourishing Phoenix, Inc.

In 2018, Don was named an Honorary Commander at Luke Air Force Base, with the 420 airmen and women of the 756th Maintenance Unit. He has been involved with many charities over the years but nothing prepared Don for the unique, eye-opening adventure he embarked on. His direct involvement with the men, women and children who call this base home has been inspiring, and impacted him in a way I could never imagine. Don has seen how dedicated these young service members are to their tasks, to their country, and how they stay focused on taking care of this base and our country, no matter what emotional issues they may be facing here or back home.
