In this role, he operated in a dual-capacity as CEO of the firm’s investment management subsidiary, Grubb & Ellis Equity Advisors, and as chairman and CEO of Grubb & Ellis Healthcare REIT II (later renamed Griffin-91 II). He led this 600-employee national investment management platform, comprised of public non-traded REITs, institutional joint ventures, separate accounts, and private syndications, from 2006 to the point at which American Healthcare Investors was founded to absorb Grubb & Ellis’ healthcare REIT business.

Hanson earned a Bachelor of Science in business administration with a dual emphasis in corporate and real estate finance from the University of Southern California. He currently resides in Laguna Hills with his wife and four children.
