ON Partners, a pure-play retained executive search firm building C-level and board leadership teams for high-growth private and public companies, private equity, and venture capital, is pleased to announce the promotion of Patrick Casey as Partner.  

Casey partners with investors and executive leadership teams to build C-level and VP organizations across industrials, consumer, AI and emerging technology, security, and government contracting. He is frequently trusted with high-stakes leadership searches during periods of rapid growth, transformation, and operational complexity, particularly within private equity and venture-backed environments. 

His recent work includes leadership placements for companies such as Avio, Watts Water Technologies, Grunt Style, BMC, and Applied Materials, spanning CEO, functional C-suite, and senior operating roles. 

“Patrick brings an exceptional level of discipline, leadership, and execution to every search,” said Bryan Buck, Managing Partner at ON Partners. “His promotion reflects the trust he has earned with clients and candidates alike, and the consistency with which he delivers results in complex, competitive markets.” 

A former United States Army Non-Commissioned Officer (NCO), Casey brings a mission-oriented leadership philosophy rooted in accountability, resilience, and decisive execution. As an Explosive Ordnance Disposal (EOD) technician, he completed more than 400 active disarmaments, developing an approach grounded in precision, discretion, and sound judgment in high-consequence environments. His broader combat service, recognized with the Bronze Star and Purple Heart, further informs his leadership style and perspective on responsibility, risk, and consequence. These principles now define his approach to executive assessment and leadership placement for investors and boards.
