As Managing Partner I head up the Monahans business.
I head our Professional Practices team and advise Solicitors and a range of owner-managed companies on all aspects of their businesses and practices.
I love to enable my clients to reduce costs, minimise the administration they undertake and allow them to have up to date information on their businesses, by providing our Monahans cloud accounting service. Depending on their needs, we will use the most appropriate packages, including FreeAgent and Xero as a part of our Business Bureau offering.
My background
I have worked for a number of professional firms ranging from large internationals to small local organisations and I also had a spell away from the accountancy profession in industry, which puts me in a great position to understand what our clients are looking for from their accountant.
Outside of work, my two teenage daughters keep me very busy. I also have a keen interest in property renovation and DIY in addition to car restoration. I like to get my hands dirty and do something slightly different than my day job.
