Shields, the company structures investment vehicles including Delaware Statutory Trusts, Qualified Opportunity Zone funds, and interval funds. Griffin Capital operates as a vertically integrated platform managing acquisition, development, asset management, and investor services for institutional rental housing. The firm focuses on multifamily communities, net-leased office and industrial properties, and clinical healthcare assets.
