In light of the former head of the Ram Truck Brand, Fred Diaz, leaving for a position at Nissan last week, Chrysler Group announced Monday who will fill this position.

Named president and chief executive officer of the Ram Truck Brand is Reid Bigland, who will also continue as head of U.S. Sales, and president and CEO of Chrysler Canada.

Most recently, he was president and CEO of the Dodge Brand. Bigland has been with the company since 2006, when he came over from Freightliner Custom Chassis Corporation, a South Carolina-based company.

Filling Bigland’s shoes at Dodge is Timothy Kuniskis, who is named president and CEO of the Dodge Brand. He most recently served as head of the FIAT Brand for North America, the company shared.

Kuniskis joined Chrysler in 1992 and “has held a series of increasingly responsible positions in the company’s business center operations and marketing organization,” they added.

Now, Jason Stoicevich will head up the Fiat Brand for North America. Stoicevich will also keep his  position as director of the California Business Center.

“In his 10 years of service with Chrysler, Stoicevich has gained experience in a variety of assignments in the company’s business center operations,” officials added.

Lastly, Bruno Cattori has been appointed president and CEO of Chrysler de México.

Cattori most recently served as director for retail sales and fleet for all Chrysler Group brands in Mexico, a position which he will retain.

Prior to rejoining Chrysler Group in early 2012, he served as president and CEO of Mercedes-Benz Mexico.

“These appointments are part of the Chrysler Group’s strategy to continuously reinforce its leadership ranks as we continue on our path to achieve our business targets,” said Sergio Marchionne, chairman and CEO of Chrysler Group. “They are a further confirmation of the depth of our talent pool and of the exceptional opportunities that are available to our people as part of their career development.”

The changes are effective immediately.
