Mark Tamis Takes on Dual Leadership Position at Seabourn and Holland America Line

Seabourn president Mark Tamis is assuming a dual leadership role, adding on the responsibility for guest experience and product development (GEPD) across both Seabourn and Holland America Line. He will begin overseeing GEPD for Seabourn immediately and for Holland America in the coming months.

The expanded role comes as Michael Smith, senior vice president of guest experience and product development announced his retirement, effective May 1, 2026, after a dedicated career shaping the guest experience and product strategy for both HAL and Seabourn.

Tamis joined the Seabourn team in November 2024. He brings more than three decades of experience in food, beverage, and guest operations across the cruise and luxury hospitality sectors. Previous roles have included senior positions at Carnival Cruise Line, Royal Caribbean, and Four Season Hotels and Resorts.  

 “As Michael begins his transition, Mark’s expertise and leadership style will allow us to continue delivering the exceptional service, culinary excellence, and extraordinary entertainment that our guests expect,” said Beth Bodensteiner, president, Holland America Line.

Smith will transition his responsibilities over the next few months and will continue as a consultant on ship refurbishment beyond that period. The company also promoted Michael Stendebach to senior vice president, food, beverage and rooms division for Holland America and Seabourn. Stendebach has been instrumental in the team’s success since joining Holland America four years ago, following more than a decade in similar roles across Carnival Corporation.

“I am truly excited to take on this expanded role while continuing to serve as president of Seabourn,” Tamis said. “Leading Seabourn is an honor, and that commitment remains unchanged. I look forward to bringing my decades of experience in luxury hospitality, guest operations, and food & beverage to further elevate the distinct guest experience cultures of both Holland America Line and Seabourn.”
