Managing Director

I am the managing director of HW Associates Limited and the proprietor of HW Associates.

Subsequent to qualifying with a top four firm of Chartered Accountants and thereafter working for an international quoted company I entered partnership in Hitchin in the early 1980’s.

I advise owner managed business clients on a broad range of matters from start-ups to sale or succession and all points in between.

I have many years’ experience of giving practical integrated commercial, transactional, compliance and taxation advice to owner managed businesses, not-for-profit entities and private clients. I understand what makes a business a success and what increases its value.

I am pleased to be the liaison between HW Associates and Accelerate.
