“We warmly welcome Vigiun to the Chiltern team,” stated John Vann, Executive Vice President, Americas. “The acquisition of Vigiun enhances Chiltern’s growing presence in Latin America, which was established nearly a year ago when we began operations in Argentina under the leadership of Oscar Podestá, our General Manager for Latin America. The knowledge and experience of Eduardo Forleo and Elisa Halker, and all of the Vigiun staff, will further strengthen our ability to serve our clients and continue our strategy for growth in the region.” Dr. Forleo has been appointed Chiltern’s Country Manager for Brazil and Medical Director for Latin America. Ms.Halker will serve as Director of Clinical Operations for Brazil.
