Charter Communications said Josh Jamison, president of Charter's East Operating Group, died Monday at age 55.
Charter said that according to the family the death was due to natural causes.
Jamison joined Charter in 1999 as vice president of operations for the company's former Northeast Division. In the following years -- due to his exceptional drive, business sense, and natural leadership qualities -- he was named president of Charter's East Operating Group.
He is survived by his wife Cathleen and daughters Elizabeth and Emily, Charter said.
Charter CEO Mike Lovett said in a statement: "Anyone who came in contact with Josh understood that he was special. Josh's energy and enthusiasm for his family, our business, and life, were truly boundless. His sense of humor was legend. He firmly believed that employees are a company's most important asset, and he demonstrated that belief every day by supporting his team to the best of his ability and inspiring them on a daily basis to go the extra mile for our customers."
Charter said funeral arrangements were pending in Newtown, Conn.
