BETHLEHEM, PA. — Just Born, Inc. has named David Shaffer and Gardner (Chip) Jett Jr., Mr. Shaffer’s son-in-law, as co-chief executive officers.

The appointment is effective immediately and comes nearly one year after former CEO Ross Born announced his plans to retire.

Mr. Shaffer was previously chairman of the board at Just Born, and Mr. Jett was an enterprise risk manager at the company.

The duo will continue to work with David Yale, Just Born’s president and chief operating officer for the past 11 years.

Just Born, the maker of confectioneries such as Peeps, Mike and Ike and Hot Tamales, said the decision will ensure that the company celebrates its 100th anniversary next year under family ownership and leadership.
