JIM AMOROSIA, CEO of G6 Hospitality since 2011, when the company spun off from Accor Hotels, has retired.

Rob Palleschi, who joined the company two months ago as chief development officer, is interim CEO.

The Blackstone Group owns G6 Hospitality. It acquired Motel 6 and Studio 6 from Accor S.A. of France in 2012 for $1.9 billion.

The company, based in Carrollton, Texas, announced the changes on April 5, saying Amorosia’s retirement was effective immediately. Amorosia ends a 33-year career with the company.

Motel 6, is a limited-service economy brand, and Studio 6 is an economy extended-stay brand. Asian American hoteliers comprise most of G6 franchisees.

Amorosia’s departure follows the retirement of Dean Savas in September. Savas was executive vice president and chief development officer for the brands for 45 years.

Palleschi joined the company in February after a stint as CEO of TGI Fridays. Previous to that he was global head of full-service brands at Hilton Worldwide.

“I’m excited to take on this new position and we thank Jim for his many years of service to the company,” Palleschi said in a statement. “Moving forward, we see a clear path for continued growth and expansion for our brands well into the future. Our keys to success will be further strengthening our relationships with our guests and our local communities and creating exciting new opportunities for both team members and franchise partners.”

Amorosia led the company through a significant capital investment program, which included $500 million in renovation improvements, said a company news release. He led the brands’ repositioning through significant investment in technology, acceleration of owned-asset sales and more than doubling the size of the franchise system. In the past five years, the company grew by 560 hotels to 1,400 in the U.S. and Canada.

G6 Hospitality also has hotels and a pipeline in Mexico, Latin America and India under the brands Estudio 6 and Hotel 6.

The company said it has the largest development pipeline in its 55-year history, with nearly 50 percent as new construction.
