I like to learn new things.  I am fortunate that forensic work gives me the opportunity to work across many different industries, different subject matters, a huge variety of issues to be investigated and to work with a wide range of people.  I love the diversity and the opportunity to explore and learn about new issues and find ways to resolve difficult problems.
By 1991 I had been working in audit for some time and realised that just checking other people’s work was not sufficiently challenging.  I had the opportunity to move into management consulting or litigation support, as it was called then.  I had always enjoyed the law aspects of my accountancy exams and training so litigation support appealed more to me.  I love the challenges this work brings and enjoy getting into the details of accounting records and spreadsheets just as much as developing an overall approach for an expert report.
I worked in big accounting firms for 27 years.  Conflicts of interest became a major issue for me and when I turned 50 I felt the time was right to try something new.  When the opportunity arose to create a new firm with Phil, I knew this was too good an opportunity to miss.  We are lucky in that we share the same passion for this work, the same vision for the type of firm we want to build and we have similar personalities.  Starting a new firm was a new challenge and, more than four years on, we are proud of what we have achieved and thoroughly enjoy all the challenges and opportunities that come with running our own firm.
I am a bit of a sports fanatic and having children keen on sport fuels my passion.  When I am not at work, I usually keep fit at the gym, play 5-a-side football, tennis, golf and run but my main focus is cycling.  I have cycled from Land’s End to John O’Groats twice, ridden in the Alps and Dolomites and recently completed the Prudential Ride London.
When I was younger I wanted to be a professional snooker player. I played a lot in my late teens and early 20s, playing in various tournaments in the South of England.  I had the opportunity to take a year out of my accountancy studying/work to see if I could cut the mustard as a snooker player but alas, I never took it.  What might have been?
