Professional background

For more than a decade, Peter has represented businesses and individuals in litigation in courts and arbitrations across the country, from trade-secret fights to contract, fraud, intellectual-property, and financial-services disputes. He also represents executives and senior professionals in high-stakes employment matters, and he runs each case himself, from the first call through discovery, motion practice, and resolution.

That work rests on a broad foundation in commercial litigation. Peter clerked for two years in federal court, then tried and resolved complex disputes at two of the world's leading litigation firms. As a Vice President at the world's largest litigation finance firm, he assessed and underwrote commercial cases as an investor, which gave him a practical sense of what a dispute is worth and how it is likely to play out. He builds each case the way that work taught him: assembling the facts into the tight chronologies that decide outcomes, and weighing every move against the economics. Today he brings all of it to a solo practice, using AI to do the document-heavy work that once required teams of attorneys, so a client gets a senior litigator's undivided attention and the leverage to take on a team of any size.
