"Riordans helped me developed my career, providing on the job training and exposure to a wide ranging client portfolio from small sole traders to large groups of companies – from basic accounts and tax returns to group demergers, re-constructions and due diligence work – through the myriad of taxes – and including Wills, Trusts and Estate Planning.
