Q: StoneTurn is known for being collaborative. Describe for us how the firm is able to work so seamlessly with clients and as colleagues.


On a recent matter, while StoneTurn was not engaged as forensic accountants in an internal investigation, we were retained by the company’s audit committee to provide the company with additional support and guidance on accounting-related matters. In this role, we worked closely with several other leading accounting and consulting firms, as well as investigative legal counsel, to provide responsive and thoughtful services to our client. During the course of the assignment, the company passed along positive feedback, as well as comments made by the other firms, that not only did all parties appreciate the collaborative nature of the StoneTurn team, but they were also decidedly impressed with the quality of the experience provided by StoneTurn across all levels.

Q: What do you believe sets StoneTurn apart?


The people at StoneTurn are some of the most talented and collegial individuals with whom I have ever worked. At many other consulting firms, there is often an individualistic culture in which professionals are encouraged to look out for themselves and maximize profits whenever possible. StoneTurn operates as one team, sharing experiences and opportunities freely. Clients, in turn, benefit from access to a broader experience base of professionals who have previously faced similar circumstances and can help clients to untangle complex problems.
