Pemberton & Co. is pleased to welcome three managing directors, each bringing deep testifying experience to our London, New York and Singapore offices.
The appointments reflect sustained growth in demand for independent expert evidence across international arbitration, fraud investigations and competition matters. Each new colleague has given evidence before courts and tribunals, and each brings a practice that complements our existing strengths. Together they expand our capacity to lead complex, multi-jurisdictional mandates from the first instruction through to the final hearing.
Our new colleagues
Isabel Warrington joins our arbitration practice in London. She specialises in quantum for construction and infrastructure disputes and has testified in more than thirty arbitrations under major institutional rules, most recently on delay and disruption claims. Nathaniel Brooks joins in New York, where he will lead forensic accounting engagements involving financial-statement fraud and post-acquisition disputes, drawing on two decades of investigative work.
Each appointment deepens a practice our clients rely on most in contested proceedings.
Mei Lin Ong joins our competition practice in Singapore. She advises on merger control, abuse of dominance and cartel damages across Asia-Pacific, and has worked closely with regional competition authorities. Her arrival strengthens our ability to support clients facing parallel investigations in several jurisdictions, and extends our economic modelling capability for the region’s fast-growing digital and consumer markets.
The road ahead
All three will work closely with colleagues across offices, reflecting our view that the strongest expert evidence draws on combined disciplines. Their appointments continue a period of deliberate growth for the firm, and we look forward to the insight and judgement they will bring to our clients’ most demanding disputes. Clients can reach each of them through their local office.
