Prior to co-founding Grupo TorreSur, Mr. Eisenstein was Chairman and Chief Executive Officer of Optasite Holding Company, Inc. Mr. Eisenstein took over Optasite at the end of 2003 and transformed the Company from a struggling wireless services provider into the nation’s second largest privately held wireless tower company, with nearly 600 strategically located towers in the United States, Puerto Rico and the U.S. Virgin Islands. Under Mr. Eisenstein, the Company raised over $250 million in equity and debt financing and grew to $23 million in tower cash flow.
