Just months after taking a top position at Minneapolis CSM Corp., Twin Cities real estate veteran Andy Deckas has left the firm.

Last August, CSM announced that Deckas would take over as CSM's president of Commercial Properties and executive vice president. But he apparently left the company earlier this month. Deckas did not return a phone call Monday.

A CSM spokeswoman, Greta Andzenge, said the departure was a "mutual parting of our ways."

Deckas came to CSM with 25 years of industry experience, most recently as president of Opus/Founders Properties, where he was responsible for the acquisition and management of more than $3 billion in assets.

Prior to that, he was employed at Heitman, one of the nation's largest real estate advisors.

Deckas was interviewed by the Star Tribune shortly after assuming the new position.

When asked at the time why he took the position, he said, " It certainly was nothing negative about Opus or Founders; this was just an opportunity. You've got a privately held company. You've got the founder and head of the firm who's at an age where he's looking at not only continuing to grow the business that he created and built, but also be able to transition leadership to build for the future."

Lori Larson, who joined CSM at the same time as senior managing director of Capital Markets, has left the firm, as well. Prior to CSM, Larson was president of Keystone Advisors LLC, and she also worked at CBRE, Opus and Richard Ellis.
