As Chaminade continues to expand and enhance its mission, the appointment of a chief operating officer marks a significant milestone in its history.

Mr. Crimmins has dedicated his career to fostering positive change and enhancing the impact of organizations. His diverse background in leadership, strategic planning, operational management, and philanthropy makes him exceptionally well-suited to oversee the business operations of Chaminade High School. In addition, having served as a member of the Board of Advisors for the past few years, Mr. Crimmins will bring his deep knowledge of the current environment that Chaminade is operating within.

As chief operating officer, Mr. Crimmins will report to President Bro. Thomas Cleary, S.M. ’81, and collaborate with the Board of Advisors and other key administrators, all working towards the continued advancement of Chaminade’s mission statement and core beliefs. He will oversee the Offices of Advancement, Alumni and Parent Relations, Campus Facilities, Communications and Marketing, the Treasurer, and finance and investments. He will also advise other areas within the school, including admissions, athletics, financial aid, and scholarships.

“We are thrilled to welcome home Brian Crimmins ’95 as our first-ever chief operating officer,” said Bro. Thomas. “His track record of leadership, dedication to education, and commitment to our Chaminade Family aligns perfectly with the need to support our current and future operational plans and strategies. The timing of Brian joining us is critical as we begin planning for our 100th anniversary [in 2030] of providing Catholic education on Long Island.”

Mr. Crimmins expressed his enthusiasm for his new role, saying, “Chaminade High School has a tremendous history of educating the whole man – body, mind, and soul. And, as someone who personally experienced this opportunity, as did my brothers, my brothers-in-law, my nephew, and my father-in-law, I understand the importance of developing Chaminade Men for our society today. In addition, I’m excited to take 22+ years of consulting – including with many colleges and high schools – and bringing that experience to my work at Chaminade.”

Chaminade High School remains committed to providing a holistic and transformative education that prepares young men for lifelong success. The appointment of Brian Crimmins as chief operating officer reinforces the school’s dedication to ensuring the necessary strategies and resources are in place to continue supporting Chaminade’s mission into the future.
