Under Mr. Grain’s leadership and with its roster of industry veterans, former regulators, financiers, analysts, owners, and operators, Grain Management has pioneered a variety of innovative financial structures that have transformed the communications industry, including the first ever asset-backed securitizations of cellular communication towers and radio frequency spectrum licenses.
