Read what our clients liked to share about our work


Our firm approached John a few years ago when we decided that we needed an independent, external approach to our annual audit cold file review process which had previously been performed internally. Since then, John has also provided us with other compliance reviews, as well as more general advice on an ad hoc basis. John is an absolute pleasure to work with, his reviews are thorough but fair, and he provides stimulating and relevant feedback for our staff. His overall advice has also been invaluable, and we will often use him as a sounding board for technical and regulatory matters. We would absolutely recommend John and are very pleased that we chose to work with him.

John has carried out cold file reviews for us for a number of years now. His annual reports provide practical advice where changes are needed and form the basis of our annual internal audit training days. In addition to his annual visit, he is always there for a valuable second opinion on any technical matters throughout the year if required.

We decided to take our Cold File Review external to the firm, we engaged John O’Donnell to support us in this vital role. John O’Donnell applies to our annual external review process, the required independent professional approach, thereby giving us the robust file reviews required for regulation. However, he retains an experienced practical perspective, which always adds positive improvement to our auditing and our file documentation.

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.

We have been working with John for many years and keep coming back due to the first class service, pragmatic approach and professionalism we have received.  The service is second to none and worthy of the highest recommendation.
