Kenner has filled several vacancies created in the administration of former Mayor Mike Yenni, who was sworn in this week as Jefferson Parish president and is taking many of his top aides with him.

Before resigning, Yenni named Assistant Personnel Director Maria Leon to be Kenner’s deputy chief administrative officer, replacing Natalie Newton, who will join Yenni’s new parish administration.

Bret Dardar, who has spent the past five years as personnel processor, will replace Leon.

Yenni also appointed Stephen Michael Petit Jr. as director of the Code Enforcement Department and Mary-Sharon Howland as the new clerk of court. Former Code Enforcement Director Aimee Vallot and former Clerk of Court Tamithia Shaw are taking jobs with Jefferson Parish.

Jay Sprague has taken over as director of Kenner’s Information Technology & Telecommunications Department. Former IT Director Valerie Waguespack also is now working for Yenni at the parish.

In the Finance Department, senior accountant Jean Caillouet will be acting assistant director. He temporarily takes over the duties of Assistant Director Victor Larocca, who is moving to a job with Jefferson Parish. Caillouet has been with the city for eight years.

Chief Administrative Officer Mike Quigley lauded the new team, saying that Yenni “was very careful to select some very qualified replacements.”

City Councilmen Mike Sigur and Dominick Impastato will serve stints as mayor until a special election later this year.

Leon, a lawyer and graduate of the Loyola College of Law, has spent the past three years in the Personnel Department.

Petit, who graduated from Tulane Law School and has been in private practice for 11 years, has worked as a police officer in Jefferson Parish, Harahan and St. Charles Parish.

Howland was director of the Community Services Department from 2006 to 2011 and also spent nearly six months as assistant director of the Purchasing Department. She was previously a property manager for 1st Lake Properties.

Sprague, who moves up from the position of IT systems specialist, has spent 17 years with the city, including 15 years in IT.
