ATS Chartered Accountants is a professional accountancy firm run by Susan Ward, a Business Accountant with over 10 years practical experience.


I got my first taste of accountancy at a young age while working (unpaid!) in my mother’s small accounts business. To my mother’s joy, I took to it quite well and continued to help for the rest of my teenage years. After leaving school, I did Accounting in College, got my BA and then continued to complete my professional qualification with Chartered Accountants Ireland. I spent almost a decade with one of Ireland’s leading firms. My specialist area, which I particularly liked and where I trained and worked for many years, was small businesses. Setting up my own practice was a natural consequence of my passion for driving businesses forward.


Tatiana Hrapelman is a qualified ACCA accountant since 2008. After completing her studies at Griffith College and Dublin Business School, she embarked on an extensive career as Financial Senior Accountant and Accounts Manager. For many years Tatiana has been successfully covering various areas of internal operations and control functions, payroll and HR, bookkeeping and Revenue returns, preparation of the management accounts and financial statements. Tatiana also served as a director on the board of several companies. As part of our ATS Chartered Accountants accountancy firm, Tatiana helps clients in all aspects of their accounting and tax needs.
