Meet the team

A little bit about us…

Joanna Ellis BSc (Hons), FCCA

Managing Partner

Jo’s background in investment banking, financial PR, television production and brand design gives her a unique perspective on clients’ affairs: spotting the key issues amongst the noise. Jo is the main contact for all clients, even when she is knee-deep in cow poo or hauling bales on her husband’s dairy farm.

Roger Thomas FCA

Founding Partner

Roger set up the practice in 1981 and, after spending 25 years as a globetrotting auditor, he gained his ACA fellowship of 50 years service in 2014. Roger continues to provide invaluable tax and accountancy consultancy to clients and to the practice.

Begonia Garcia

Senior Accountant

Begonia joined Thomas & Ellis as senior accountant in spring 2014 after four years at Monahans and nine years at Richardson Groves. Begonia does a brilliant job of keeping everyone in line and making sure the office is always as warm as Barcelona.

Karen Beebee ACIPP


Karen is our payroll guru and she brings a whole team’s worth of knowledge to our payroll department. Karen is great at unravelling tricky payroll problems and she is unflappable in a crisis, which ensures clients and staff get paid accurately and on time.

Justine Williams BA(Hons), AICB CB.Cert

Accounts Assistant

Justine is a qualified bookkeeper, an Associate member of the Institute of Certified Bookkeepers and has held a variety of accounting roles prior to joining Thomas & Ellis in January 2017. Her methodical and thorough approach means that she is ideally suited to providing the best possible support to the rest of the team and our clients.

Rebecca Costello

Office Administrator

Rebecca is our newest recruit, having joined in October 2017 after relocating to Wiltshire from Norfolk. Rebecca has an extensive administrative background and a can-do attitude to the more mundane tasks within a busy office! Her aim is to ensure the Thomas & Ellis office is a calm and organised environment and to support the accountancy team in providing the very best possible experience for our customers.
