In summary

Although Mark originally qualified as a Chartered Accountant, that was all a long time ago. After a very successful 25-year career in the accountancy and tax profession he realised he wasn’t enjoying what he was doing. He decided to focus on those elements of his career that had long given him a positive buzz.

Mark has extensive network reach through his blogs, talks, social media activity, articles and his regular newsletters that go to thousands of accountants every week. His website and blog attract many thousands of visitors each month and his opt-in email database of 15,000+ contains over 10,000 accountants.

Mark has long been a go-to guy for comment and insights regarding the accountancy profession as well as a regular judge for accountancy related awards ceremonies.

In recent years Mark has developed a framework containing 7 key principles that are relevant for all professionals who want to STAND OUT from the pack. The principles are key to generating more work as well as to helping professionals be remembered, referred and recommended (for the right things!)

There are many elements underlying the 7 key principles and Mark draws on these when mentoring clients, when speaking at events, and when writing his blog and articles for the professional press. He has had well over 200 practice focused articles published and these have been viewed well over ONE MILLION times.

Professional Background

Mark’s career followed the traditional path of children’s party entertainer, chartered accountant, magician, tax adviser and professional speaker.

He qualified as a Chartered Accountant (not the boring type) in 1982 and then spent over 25 years advising on tax during which time he was a tax partner at (Crowe) Clark Whitehill. He was subsequently headhunted to be Lead Tax Partner of the professional practices team at BDO in London. He had been a regular writer for the professional press since 1987 (as shown on this list).

Mark was elected Chairman of the ICAEW Tax Faculty from 2003-2005. During this time he was an ex-officio member of the Council of the Institute.

Over a six-year period, from 1999, Mark represented the ICAEW in numerous discussions and debates with HMRC, HMT and other professional bodies. Since about the same time he has sat on and chaired various Institute committees and joint working parties with other professional bodies. In 2012 he cut back his activities here and simply continued with his role (latterly Chairman) on the Institute’s Ethics Advisory Committee.

The next phase

In 2006, as he approached the age of 50, Mark realised that he had stopped getting a buzz from giving tax advice. An entrepreneurial spark, dormant for over 25 years, had been reignited and he resolved to try something new. He also wanted to focus on those elements of his career that he found most enjoyable – speaking, writing, training, mentoring and facilitating.


The Inner Circle for Accountants – is an exclusive peer-led group that Mark facilitates to help sole-practitioner accountants achieve greater success – on their own terms.

The Tax Advice Network, of which Mark is Chairman, was established in 2007 and is the UK’s highest ranked lead generation website for tax advisers and accountants.
