If there was one piece of advice you would give your younger self, what would it be?

“Don't be too hard on yourself.”

I joined the firm as a trainee accountant in 2002, after sitting my A-levels at King Edward VI Grammar School in Louth.

I obtained my AAT qualification and continued my studies, qualifying as a Chartered Accountant in December 2006. I then went on to be appointed as partner in October 2020.

I manage a diverse portfolio largely comprising owner managed businesses across a variety of sectors. I firmly believe that each business and person is unique and I am committed to delivering tax and accounting advice tailored to suit each client’s objectives.


Outside of work I enjoy reading and spending time with my young family, chaperoning and volunteering, wherever possible, at their long list of extra-curricular activities.
