Mark qualified as a Chartered Tax Adviser with Arthur Andersen in 1989, having previously worked in the tax departments of a small and a medium-sized firm. He is a partner of The Professional Training Partnership. Since 1993 he has been lecturing on a wide variety of tax matters for some 25 years to qualified practitioners and industry specialists in the UK and overseas. His ability to quickly establish a rapport with his audience, and discuss complex matters in a practical, and understandable style has led to Mark becoming much in demand on the lecturing circuit. Away from tax, Mark spends Sunday mornings coaching and refereeing youth rugby union, and sometimes spoiling a perfectly good walk with a vain search for a well-hidden geocache.
