HaysMac, the award-winning accountancy and tax advisory firm, is proud to announce the promotion of Lotte Williams, Nicky Dockree and Jackson Berry to Director.
These promotions are a testament to HaysMac’s long-standing commitment to developing talent from within and strengthening sector-led leadership across the firm.

Lotte joined HaysMac in 2014 and has played a pivotal role within the Retail team, advising a range of fast-growing, innovative businesses in the sector. As Head of HaysMac’s Retail & eCommerce sector team, Lotte has helped shape strategy, business development and specialises in supporting scale-up and high-growth clients navigating rapid change.
Her leadership on complex audit and assurance engagements – often involving multi-entity structures, international operations, and private equity stakeholders – has earned her the trust of clients and colleagues alike. Lotte is also deeply committed to mentoring talent and driving forward an inclusive and supportive working culture.
Homegrown talent, Nicky, joined HaysMac in 2016 and is a key member of the firm’s Hospitality team, advising clients across the hotel, leisure, restaurant and pub sectors.

Nicky has also co-founded the HaysMac Future Gen network, as well as the Female Event Series which focuses on championing female talent across the professional services.
Jackson joined HaysMac in 2021 and has become an integral part of the firm’s Social Purpose team, supporting a diverse range of not for profit organisations, charities, and social enterprises. With a strong background in audit, Jackson combines technical expertise with a deep understanding of the unique challenges faced by professional institutes and membership bodies, independent schools and arts and culture focused organisations, from regulatory compliance to strategic growth.
Jackson brings a blend of technical excellence, commercial awareness, and a genuine passion for purpose-driven work. Jackson is a valued advisor to boards and leadership teams, offering insight that balances both strategic vision and operational detail.
