Work With Accountants Who Can Help To Transform Your Business.

Amanda Williams

FCA - DIRECTOR

Having qualified in 1990, I have been advising clients as a partner in practice since 1995. Iʼm equally at home providing tax advice to an individual or transaction support to a large owner-managed business. My technical knowledge covering a range of business sectors is bolstered by the practical experience of running a business of my own.

Away from the office, I enjoy spending time with friends at museums, galleries and the cinema, with The Proms and The London Film Festival being annual highlights. I also enjoy regular walks around Londonʼs parks, with Richmond Park being my favourite and most convenient.

Thomas Pottinger

FCA - DIRECTOR

Iʼm a seasoned Chartered Accountant and Director at Porter Garland. I qualified as a Chartered Accountant in 2003 and have since built over two decades of experience in advising a broad and diverse portfolio of corporate clients.
Throughout my career, I have developed strong, long-term relationships, giving me deep insight into multiple business sectors, including property, consultancy/freelancers, retail, and manufacturing. I believe in ʻnurturing your growthʼ and Iʼm passionate about supporting my clients as if their business was my own.
Away from the office, I value family life highly. I enjoy walking, gardening, dining out, swimming, and holidaying with my wife and daughter.

Nikki Vanstone

Senior Client Manager

I joined Porter Garland in June 2018 as a Senior Client Manager, bringing broad experience across accounting and taxation for both corporate and non-corporate clients. I qualified as an ACCA member in 2018 and became a Fellow in 2023. I work closely with the directors to support owner-managed businesses and personal tax clients, delivering clear, practical advice. Building strong client relationships is at the heart of my role, and I enjoy helping clients navigate their accountancy and tax matters with confidence.

Justine Taylor

Senior Client Manager

My accountancy career began in 1994, giving me more than three decades of experience supporting clients across a wide range of sectors. I joined Porter Garland in 2004, qualifying as an ACCA member in 2005 and becoming a Fellow in 2010. As a Senior Client Manager, I pride myself on building strong, long-term client relationships. I work closely with corporate clients on management accounts, statutory accounts, and taxation, while also supporting sole traders and partnerships with annual accounts and Self-Assessment tax returns, providing clear, reliable advice they can trust.

The leadership team relies upon the support and skills of all our colleagues enabling us to provide the full range of services.
