What is next for the new president of SIOR Arizona

Colliers International’s Rob Martensen selected president of the SIOR Arizona Chapter

AZ Big Media, March 15, 2018 - Rob Martensen didn’t intend to become a real estate agent. In fact, he received a psychology degree from Arizona State University. However, “If you can understand why people think the way they do, you can do anything with that,” he says.

Initially, Martensen thought he would obtain his real estate license because he and his father planned to buy, fix and resell houses. When his dad changed his mind, he began selling homes to his recently-graduated friends, but soon gravitated toward industrial real estate.

“My dad was in the rigging supply business and my uncle owned a furniture company,” he says. “I grew up around manufacturing facilities and warehouses, so I was more comfortable in that field than an office building.”

His decision to enter commercial real estate for industrial brokerage paid off too.  Last year, he celebrated his 20th anniversary at Colliers International Greater Phoenix where he is now the executive vice president of the industrial properties division.

Last November, Rob Martensen was selected to be president of the SIOR Arizona Chapter after serving on the organization’s board for the last eight years.  He says, “To lead and promote the organization is a real achievement for me.”

The main goals for his two-year tenure focus on exposure and promotion to help people truly understand what SIOR is. “If someone wants to know about industrial and office real estate, they should consult an SIOR broker,” Martensen says. “If they want to know who the strongest, most ethical brokers are, they should use one with the SIOR designation.”
