Strategic Management Coaches and Trainers

Eric Denniston called Mexico City home for 27 years, and Spanish was his first language. The culture, traditions and Latin flavor are an ingrained part of his style and how he interacts with people. In his early career he frequently climbed one of the better-known volcanoes on his weekend bike rides with a close friend. He shares his cycling enthusiasm with his wife and business partner.

Jeri Denniston called the jungles of Indonesia home for the first 10 years of her life while her father worked as a corporate trainer with the Ford Foundation and then Standard Oil of New Jersey (Exxon). She spoke Bhasa Indonesia like a native as a child, which helped developed her facility for languages later on.
