  • Four additional key leaders from JACK Entertainment to join the Bedrock team later this year
  • Bill Emerson to continue his role as Vice Chairman of Quicken Loans and Rock Holdings


August 29, 2019 [DETROIT] – Bedrock is pleased to announce today a series of leadership changes that will position the company for its next chapter of growth. Effective September 1, Matt Cullen will be joining Bedrock as Chief Executive Officer and Mark Dunkeson will be joining as President and Chief Operating Officer.

Cullen and Dunkeson have led JACK Entertainment (“JACK”), a casino gaming and racino company, which owns and operates properties in the Midwest, and will be expanding their role as key leaders within the Rock Family of Companies. Cullen will continue to serve as Chairman of the Board for JACK.  Dunkeson will hold the position of Chief Executive Officer of JACK and remain a member of the Board of Directors.

“It is an incredible honor to begin working with the 600-plus passionate team members at Bedrock who, in just eight short years, have played such a significant role in driving Detroit’s new era of optimism and growth,” said Cullen. “With transformational developments currently underway throughout the city, and more big projects on the horizon, Bedrock will continue to be an engine for Detroit’s resurgence, and I am excited about being a part of that.”

Prior to JACK Entertainment, Cullen spent 29 years at General Motors (“GM”), where he was general manager of economic development and enterprise services. In addition to coordinating economic development initiatives in the communities in which GM operates, he created a shared services organization and had responsibility for the corporation’s vast 450-million-square-foot global real estate portfolio.

Cullen was chief architect of GM’s $500 million acquisition and development of the Renaissance Center as the automaker’s global headquarters. Since 2003 he has helped oversee the billion-dollar redevelopment of the city’s international riverfront as the founding chairman of the Detroit Riverfront Conservancy, whose vision is to create more than five miles of contiguous public access and linked parks along the river.

Prior to arriving in Detroit in 2013, Dunkeson spent 20 years in commercial gaming, resort, and hospitality development where he led operations for several multi-property divisions of Red Rock Resorts. As Senior Vice President of Operations for the luxury brand division, he oversaw operations of properties including, Red Rock Casino, Resort and Spa, and Green Valley Ranch Resort, Spa and Casino. Prior to that, Dunkeson led and operated seven other gaming properties for Red Rock Resorts, and also spent five years as their Corporate Vice President of Development, spearheading the company’s expansion initiatives.

With these changes, Bill Emerson, currently Bedrock’s acting Chief Executive Officer, will continue to support the company through the transition and then continue his role as Vice Chairman of Quicken Loans and Rock Holdings.

“Matt is the right leader at the right time for Bedrock,” said Emerson. “His experience and leadership will be crucial as the company moves forward. He has been instrumental in numerous large-scale initiatives not only within the Rock Family of Companies but in a variety of civic roles including his work as the Chairman of the Detroit Riverfront Conservancy and Chief Executive Officer of the QLine.  Together, Matt and Mark, with their combined business and hospitality expertise will allow the company to continue to be a driving force in Detroit.”

In conjunction with the new leadership additions, Jim Ketai has decided to step down from his role as Chairman of Bedrock to pursue other opportunities.

“Jim’s expertise laid the groundwork for Bedrock,” said Emerson. “He passionately led the team as we acquired property after property, built ground-up developments, renovated historic buildings and changed the entire conversation around what Detroit is and what it will become.  We are grateful for all Jim has done and we wish him the best in his future endeavors.”

In addition to the appointment of Cullen and Dunkeson, a number of additional key leaders from JACK Entertainment will be joining Bedrock later this year, including:

  • Glen Tomaszewski will transition from Executive Vice President and Chief Financial Officer of JACK to Chief Financial Officer of Bedrock. Tomaszewski is a 30-year veteran of the finance industry and joined JACK Entertainment’s corporate office in 2015. Previously, he was Chief Financial Officer of Greektown Casino-Hotel, and served as Vice President, Chief Accounting Officer, Controller and Treasurer at Borders Group, Inc.
  • Dan Reinhard, Senior Vice President of Government Relations and General Counsel at JACK, will join Bedrock as General Counsel. Reinhard joined JACK in 2011 and oversaw all government relations and legal affairs for the company. Prior to joining JACK, he was at Calfee, Halter & Griswold LLP, where he led complex government strategies for clients in legislative, development and regulatory arenas.
  • Alyse Martinelli, currently JACK’s Senior Vice President of Human Resources, will join Bedrock’s team as Chief People Officer. Martinelli joined JACK in 2017 and was instrumental in building a successful culture within the organization. Prior to JACK she held leadership positions at Reel Health Network, a growing medical technology start-up, and LafargeHolcim, a global building materials manufacturer. She was an associate general counsel at AT&T Inc. where she was in-house counsel for over 20 years.
