About Barrons.
Built around people, not just numbers.

Gary is our Managing Director and has been part of the Barrons story since 1985, leading the firm’s continued development of proactive, commercially focused services that combine technology, AI and automation with genuinely people-led client relationships.

Gary first joined Barrons on work experience, and his relationship with the firm has grown ever since. Four decades later, as the majority equity stakeholder, he remains closely involved in shaping the direction of the business and the way we support our clients.

Having worked both in practice and industry, Gary understands the pressures, opportunities and everyday realities that business owners face. His experience includes roles as Finance Director for SME businesses and as a self-employed consultant, giving him a strong commercial perspective as well as technical expertise.

Over the years, Gary has supported business owners, high street banks and turnaround specialists with business turnaround, independent banking reviews and strategic projects. Clients often value him as a trusted sounding board — someone who will listen, ask the right questions and offer honest, practical guidance when it matters most.

Gary is especially passionate about making advice personal. He believes every client and every business is different, so his approach is to understand what really matters to them before helping identify opportunities, strengthen strategy and build a more resilient future.

His specialist areas include:

• Mergers, acquisitions and business valuations
• Business turnaround and interim financial management
• Fractional Finance Director support and non-executive director roles
• Business development and growth planning
• Strategic planning, forecasting and cash management
• Independent banking, finance and management reviews

Outside Barrons, Gary has also given his time to South East and Central Essex Mind, serving as Chair after more than five years as a trustee — a role that reflects his longstanding commitment to supporting people and the wider community.

Socially, Gary maintains a strong interest in sport, and has attended World Cup Finals covering football, rugby and cricket as well as supporting England in the last two European Championship Finals.

Running a business comes with enough challenges without having to worry whether you’re paying more tax than you need to or missing opportunities along the way. My role is to give business owners the confidence that everything that can be done is being done, so they can focus on growing their business.

I advise owner-managed businesses, helping them navigate the ever-changing world of tax with practical, proactive advice. While compliance is an important part of what we do, I believe the real value comes from looking ahead, spotting opportunities and making sure clients are in the best possible position before decisions are made, not after.

Whether that’s through corporation tax planning, succession planning or wider tax advice, my aim is always the same: to give clients peace of mind that their tax affairs are being looked after properly, so they can spend more time doing what they do best – running their business.

Outside the office, I’m usually in the gym, watching football or convincing myself this is finally the year I’ll win Fantasy Premier League. I also dabble in a bit of golf here and there, although I don’t claim to be any good. When I get the chance to switch off, I enjoy a good science fiction or fantasy novel – Red Rising and The Will of the Many are two I’d happily recommend.
