Leading UK and Ireland professional services firm, AAB, has announced a new Head of Office in Aberdeen. Derek Mair is set to step into the role as Head of Office, succeeding Graeme Allan, from 1 April 2025.

With over 1,000 team members across 14 offices, AAB has experienced significant growth in recent years. Nonetheless, as home to more than a quarter of AAB’s team, Aberdeen remains a core part of the firm’s strategy. The appointment of a new Head of Office reinforces AAB’s commitment to strengthening its regional hubs, supporting its people, and delivering exceptional service to clients.

Derek Mair, who joined AAB in 1996, specialises in audit, assurance and advisory services for businesses ranging from start-ups to large international groups. He has played a significant role in AAB’s growth in Aberdeen, with his extensive experience in complex audits spanning multiple sectors, including food and drink, hospitality, energy and shipping. Known for his collaborative approach, Derek is dedicated to fostering growth within AAB, mentoring the next generation of professionals and delivering strategic financial insights to clients with intricate business structures.

In his new role, Derek will continue advising his audit clients while also working closely with AAB’s Heads of Offices across the country to enhance the firm’s ability to provide integrated, market-specific solutions.

Commenting on his appointment, Derek said: "Our team in Aberdeen continues to grow from strength to strength, helping clients achieve their personal and business ambitions with a diverse range of expertise under one roof. I am honoured to step into this role and look forward to guiding our team through AAB’s next phase of growth, ensuring we remain at the forefront of innovation while delivering tailored solutions that meet our clients’ evolving needs."

Graeme Allan, who has been at AAB for more than 18 years, has been instrumental in developing and executing AAB’s strategic growth plans over the past decade in his role as Chief Executive and latterly both Group Executive Director and Head of Office in Aberdeen. He will transition into a Non-Executive Director role, remaining on the AAB Group Board of Directors.

Graeme added: "I am incredibly proud of what we have achieved at AAB, a testament to our talented team and their unwavering commitment to our clients. Aberdeen is where our journey began, and it remains a vital part of our future. Appointing Derek as Head of Office strengthens our focus on supporting our people and expanding our capabilities in the region."
