Brian Robin is stepping down from Monday Properties, but will stay on for some time as an advisor.

NEW YORK CITY-Monday Properties president and COO Brian Robin has stepped down, chairman and CEO Anthony Westreich confirms to GlobeSt.com’s Rayna Katz. Robin will vacate his post on Jan. 31 but will stay on with the company as an advisor until his position is filled.

Westreich put on his best game face in telling GlobeSt.com what’s next for the company. “We have new investment goals and a strong investment team. Dang Phan is assuming the role of CIO and Timothy Helmig will become the COO.”

It was unclear what Robin’s next steps will be. He did not return a call from GlobeSt.com and Westreich didn’t know of Robin’s plans—or why he’s leaving, saying only, “I know Brian is looking for his next challenge.”

At Monday, Robin oversees all of the company’s corporate and portfolio operations, including leasing and marketing, property management and project development.  He has complex capital transaction experience in excess of $11.4 billion and is said to be an “expert at identifying asset risks and creating opportunities to build asset value.”

Phan previously was the COO, CFO and managing Partner at Grove International PartnersHelmig, an EVP and chief development officer at Monday, is head of the metropolitan Washington DC region for the company. He has two decades of experience in commercial real estate.

Says Westreich of Robin, “I had 11 great years with Brian and I wish him the best. He’ll stay a close friend of mine and of the firm’s.”
