When working with our Entrepreneurial and SME Services team, businesses will have a local relationship partner that understands their challenges and opportunities with the added benefit of access to Grant Thornton’s wider stakeholder, investor and specialist advisor connections in the UK and around the world.”
Tatiana Gullan, Audit Director in the Entrepreneurial and SME Services team, said:“I am proud to have joined Grant Thornton at a very exciting time and am looking forward to helping grow the new team and working alongside the South East’s business leaders. As the economic landscape is evolving at an increasingly rapid pace, it can be hard for businesses without large teams of specialists to navigate potential barriers and stay competitive. This can make it difficult to focus on priorities, whether that’s international expansion, exploring a sale or entering a new market. We can scale and evolve with your business and adapt our approach accordingly, without losing the local, relationship-led approach.”
Heather Boden, Audit Director in the Entrepreneurial and SME Services team, said:“I am excited to support and grow the Entrepreneurial and SME Services business and further develop long-standing relationships with clients. Having access to the multidisciplinary talents and international specialists within our newly launched team is a valuable asset. It allows access to global experts in everything from personal and corporate tax as well as specialist tax services, such as R&D and employment taxes, to sector experts in different industries, technology and digital skills, ESG, M&A, and Consulting. This allows businesses to cope with complex pressures without having to shift focus from their vision.”
