As CAO, Matthew will continue to report directly to Stewart Hall, Chief Executive Officer. He will maintain his existing responsibilities while taking on broader responsibility for supporting the execution of the Company's strategic priorities, strengthening coordination throughout the holding company, and driving operational efficiency across the platform.
Matthew joined Crossroads Strategies, one of the Group's founding member firms, seven years ago before progressing to a cross-functional position with PPHC. He was involved in the Company's AIM IPO in 2021 and played a key role in the recent listing on the Nasdaq Global Market.
The position of Chief Administrative Officer has been vacant since the retirement of Bill Chess in July 2024.
Stewart Hall, CEO of PPHC, commented:
"As PPHC continues to expand globally and enhance its suite of services and portfolio companies, the CAO position is increasingly important for the Company. Matthew has played critical roles going back to our AIM listing over four years ago in investor relations, intercompany relations, talent management, M&A, and business development. His knowledge of each of our member companies, their services and people is unmatched, and I am pleased to elevate him to the position with the Board's approval. Filling the CAO position will allow us to continue to drive intercompany synergies and support our number one asset - our talented and skilled practitioners across the globe."
