I have been really happy with the service received from John O’Donnell & Co. We started with
regular external cold file reviews for ISQC1 and also moved onto hot file reviews for risky/complex
audits such as listed plcs and client money audits. The reviews are usually done quickly and to tight
deadlines and John will often uncover issues that need further work or clarification. Some audits had
contentious issues and John’s advice helped me a lot to find a way forward and to minimise the risk
of giving an inappropriate opinion.
