Matt CraneDirector OMNIAP
Alan Hennessey has acted as my Accountant and Tax Advisor, since I first started my own Business, back in 1978. Amazing, over 40 years. In all that time, Hennessey & Co. have always acted in my best interests. Given god legal & Government advice and ensured that all my obligations are completed on time. As I am extremely happy with their service, I have recommended them, to others, in the past.
