Grosvenor has called on former Calgarian Mark Purdy to share the load of its retiring chief investment officer.

Purdy will become Grosvenor’s managing director of North American asset management on January 1, the global property owner and developer announced. He will oversee all asset management activities across the North American portfolio and lead sustainability efforts as the firm seeks to meet its carbon-reduction ambitions for the portfolio.

Michael Beattie’s position is being split in two as he retires after 23 years with Grosvenor, including the last 12 as CIO. Angela Biggs will become managing director of investments, leading the company’s acquisitions and dispositions, as she inherits Beattie’s other responsibilities. Both Purdy and Biggs now serve as senior vice-presidents of investment in San Francisco.

Since joining Grosvenor’s Calgary office in 2008, Purdy has held several roles across the firm’s U.S. and Canadian operations, including portfolio leasing, management, and acquisition and dispositions of multiple property types. He studied human resources management and tourism at the University of Calgary and Southern Alberta Institute of Technology (SAIT), which is also located in the city.

Before joining Grosvenor, he spent seven years as an associate with CBRE in Calgary, where he focused on client-based negotiations and transaction management.

Beattie served with Grosvnor in Vancouver, where he has most recently been based, and Calgary, where he worked before joining the company. He has also worked for the firm in San Francisco and Washington, D.C.

Beattie is a University of Calgary graduate.
