Apex Group Ltd. (“Apex” or “the Group”), the leading global financial services provider, is pleased to announce the appointment of Kimberly DeTrask as Chief Financial Officer (CFO) and Maxwell Johnston as Chief Business Officer (CBO). 

Effective 1 October 2025, Kimberly joins Apex Group from State Street, where she has served for over 12 years, most recently as Treasurer and Executive Vice President. Before joining State Street, Kimberly spent more than 14 years at the Federal Reserve Bank of Boston, where she worked in the Risk and Policy unit, contributing to key regulatory and risk frameworks. 

She has held multiple leadership roles in Finance and Treasury across London and Boston, and her previous role as CFO of State Street International highlights her extensive experience in global financial operations and strategic leadership. Kimberly is also a Chartered Financial Analyst (CFA) and an alumna of the CFO Leadership Program at Harvard. Reporting directly to Peter Hughes, Founder & CEO, Kimberly will join the Group Executive Committee and in her role of CFO, she will be focused on delivering a future-looking finance function, which will enable the global business to drive institutional sophistication through its finance infrastructure. 

Kimberly’s appointment reflects Apex Group’s commitment to attracting top-tier talent to support its mission of delivering exceptional service and value to clients worldwide. 

Peter Hughes, Founder & CEO at Apex Group said, “Kimberly is a highly experienced and accomplished Finance leader and an excellent addition to our leadership team. Her deep financial expertise and global perspective will be instrumental as we continue to scale and innovate across our business.” 

In addition to Kimberly’s appointment, Maxwell Johnston, an existing member of the Executive Committee who has held several roles in his 8-year tenure at Apex Group, has been appointed Chief Business Officer. Previously holding roles including driving M&A strategy, Chief of Staff and most recently as interim-CFO, Maxwell’s expertise in commercial strategy means he is well placed to focus on driving commercial alignment across the Group’s regional functions and support the enhancement of client experience across each jurisdiction.

Peter Hughes added, “Max’s appointment as Chief Business Officer reflects our commitment to strengthening our commercial capabilities and local delivery to support the value we can offer our clients. His focus on driving transparency, alignment and enhanced processes through our regional operations will be instrumental as we continue to evolve and mature our business operations and drive organizational transformation.”
