Barnes Investment Team Colliers International

I specialize in office, owner-user and investment real estate services. Let me put my experience to work for you to simplify the process of buying, selling and leasing commercial properties.


I help property and business owners navigate the complexities of buying, selling and leasing small-to-medium sized commercial properties throughout metropolitan Phoenix. As an investment sales specialist, I work closely with clients to achieve their financial goals through property acquisition, disposition and leasing.

With more than 30 years of commercial real estate experience in metropolitan Phoenix, clients rely on my in-depth market knowledge, insight and expertise to help them navigate through strategic decisions that align with their business objectives.

With an extensive background in creatively marketing owner-occupied buildings, I am known by the brokerage community as the “go-to” person for selling 5,000 to 50,000-square-foot office properties in Central Phoenix.

I place great value in performing with integrity, providing unparalleled service and establishing long-term relationships with both clients and peers. I partner with clients to ensure their success, treating each transaction as it were my own investment.
