Sorenson, in the release, added that Reiss’ “extensive global and broad leadership experience combined with her 17 years in the hospitality industry” will complement the legal department.

“Rena will be a transformative leader who will continue to elevate the company's commitment to excellence and integrity,” Sorenson said.
