Meet The Team

Ridgefield Consulting is an independent firm of Chartered Accountants based in Oxford and Henley-on-Thames

You only have to take a quick scroll down below to see how we may not look like your typical accountants. What has really made Ridgefield Consulting different from other firms is our highly inclusive and collaborative culture which has been naturally influenced by our incredibly diverse team. Not only can we cater for over 12 different languages fluently; our skills, experience, and backgrounds allow us to connect and build meaningful relationships with our clients.
Fed up of being a cog in the corporate wheel, Simon left the City (and EY) in 2010. A passion to challenge the status quo in Oxford; which, having now succeeded through a combination of strategic acquisitions and strong organic growth, Simon now strives for excellence to secure the firm as the market leader in the county.

Grace is an ACCA finalist. Being a highly sought-after accounting and finance graduate, her options were numerous. She was recommended to Simon from a personal connection and the decision to take Grace on has not been looked back on since. Rising rapidly through the ranks she now heads up the operational management of the practice.

Grace Tan | Practice Manager

Brian has a Top 4 City background. He is now responsible for the firm’s quality and risk assessments; therein, all compliance and regulatory matters.

Mi Mon is an FCCA qualified accountant and has been with the firm for over 5 years. Initially starting off to assist with the January self-assessment deadlines, she has become one of the firm’s tax planning experts.

Kizzy achieved her Digital Diploma in Professional Marketing with flying colours from the Chartered Institute of Marketing in 2020.
