Who we are
We are a female founded and led boutique accounting practice providing expert witness and forensic accounting services.
Our founders are chartered accountants and fellows of the ICAEW, with a combined 65 years’ experience in this field and are all recommended experts in Who’s Who Legal.
On 6 December 2022 we launched our specialist practice, offering Big Four quality service with the flexibility and responsiveness that comes from a small, dedicated team without the independence concerns that come from other service lines.
How we help
We act as experts in litigation, arbitration (including investment treaty claims) and expert determinations, dealing with accounting, financial and valuation issues.
We can help at all stages of a case, from preliminary views on damages when deciding whether to launch proceedings or seek funding, through mediation and settlement discussions, to formal expert appointments.
We act for claimants, respondents/defendants, tribunals, funders, buyers or sellers in M&A disputes, as advisors, shadow experts and as independent expert determiners.
We provide our services in many sectors and across the world (we have acted in recent cases in Africa, Asia, Europe, Middle East, and Latin and North America).
How we work
We are passionate about what we do, and we care about our work product.
We have a hands-on approach to all our cases and are fully involved at all stages of the work.
We are cost-effective and our clients and legal teams benefit from our expertise and experience, 30+ years of which was in Big Four professional services firms.
We collaborate with each other and are friendly and easy to work with.
