Johnston Carmichael has announced the appointment of Teresa Gilligan as audit director to support its continued investment in the North East.
Gilligan joins the accountancy and business advisory firm with more than 17 years of experience in audit and assurance, gained across major professional services firms. She has worked with a diverse range of clients, including industrial manufacturing, logistics, retail and property businesses.
A dual-qualified accountant, Gilligan is both a chartered and a certified public accountant. She has spent a significant part of her career working internationally and brings extensive experience delivering audit engagements under both UK and US reporting standards.
Based in Aberdeen, Gilligan will focus on developing her audit portfolio across a broad client base, with a particular emphasis on the energy sector. The firm supports more than 800 businesses operating in this industry.
Johnston Carmichael audits more of Scotland’s top 100 businesses than any other accountancy firm. Gilligan will also support the wider team as the company continues to grow and develop its audit services.
Gilligan said: “I’m pleased to be joining Johnston Carmichael at such an exciting time for the firm. It has a well-established reputation for delivering high-quality advice while maintaining a genuinely collaborative and client-focused approach.
“The energy sector is such a vital part of the North East economy, and I’m looking forward to working with clients across this space, supporting them through the challenges and opportunities presented by a changing landscape.”
David Wilson, Aberdeen office head and audit partner, added: “The energy sector is undergoing a period of profound transformation, and businesses operating within it face a uniquely complex set of financial reporting and regulatory challenges. Gilligan’s expertise means our clients in the energy industry can have confidence they are receiving audit and assurance services that truly reflect the realities of their sector.
“As we mark 90 years in business in 2026, Gilligan’s appointment reflects our ongoing investment in our people and our future. With almost 900 colleagues across the firm, her values and experience align strongly with our culture, and we look forward to the contribution she will make to our audit team.”
