Central 128 Suburban Team

John Carroll, III joined Colliers International in 1993. He is an executive vice president and shareholder in the firm.

John has represented developers, institutions and companies in the leasing, sale, disposition and acquisition of real estate in the Greater Boston Metropolitan area.  Throughout his career with Colliers International, John has represented numerous owners in the leasing of over 3 million square feet of space.  In addition, he has completed over 200 tenant representation transactions totaling more than 2 million square feet.

As a senior vice president on the Central 128 leasing team, tenants and landlords depend on me for candid and reliable advice as it relates to Boston’s central suburban real estate market. In a dynamic territory, comprising office, lab, flex and industrial space, I enjoy collaborating with my immediate team and other key specialists in the Colliers organization to strategize the best solutions for our clients.

I began my career in real estate after first working at Welch’s Food Inc. where I was exposed to many different sides of their day-to-day business operations such as sales, analytics, and financials. Looking back, beginning my career on the corporate side ultimately provided me with critical insight into what drives many of our clients, and has allowed me to better understand their perspectives and goals, and advise accordingly.

Although I have been in the business for over a decade, I appreciate the churn and overall evolution of the market that ensures constant opportunities to learn something new. Whether I am touring a building, viewing an upcoming project in the market, or meeting a client, each day brings with it a fresh and unique experience.

When not in the office, I enjoy spending time with my wife and two young sons, especially participating in outdoor activities.
