Conceived of and designed by Gary Shamis, Managing Partner Bootcamp (MPB) is a comprehensive opportunity to take your firm-management skills to an elite level and revolutionize the way you think and act in your leadership role.

Attendees are required to commit to two intensive, three-day sessions with courses led by subject-matter experts.

Whether you are a seasoned managing partner or new to the role, your willingness to engage, learn, and grow will be a game changer for you and for your firm.

Attendance is limited to an intimate group of participants engaging and interacting in a confidential setting.

In this game of high-stakes, don’t leave your results to chance. Change the way you make decisions by choosing to attend MPB. It’s not another practice management conference, it’s a ‘managing a practice seminar’ for managing partners wanting to gain competitive advantage and function at an elite level.

Restaurant Board Participation


Gary Shamis has been in restaurant accounting and consulting for more than thirty years.

In SS&G’s restaurant group, he and partner Brad Saltz created one of the first successful niche practices of a non-Big Four accounting firm in the country.

His leadership secured the firm’s position as a most sought-after resource for restaurant companies in the U.S. over the last two decades. He has an innate ability to know what the industry’s needs are and pioneers ways to deliver.

Gary continues to lend his expertise, serving on the boards of leading restaurant companies and advising on financial, managerial, and operational issues related to the restaurant industry.
