Jonathan is an English qualified solicitor-advocate, and a litigation partner based in Steptoe's London office.  He has practiced for over twenty years in resolving complex disputes, both domestic and international, from their inception through to settlement or trial.

Jonathan read Philosophy, Politics and Economics at Christ Church, Oxford, before obtaining an M.Sc. with distinction in Construction Law and Arbitration from King’s College, London.  He is one of Legal Business's rated “Legal Experts” in construction, and recognised as one of Thompson Reuter’s “Super Lawyers”.  Chambers & Partners guide describes Jonathan as "very capable and knowledgeable" and he is praised by the Legal 500 guide for his “robust academic knowledge and an unassuming manner” and "ability to understand a business and the factors at stake quickly and thoroughly."

He has extensive experience of contractual disputes arising from major construction and engineering projects, including process plant, roads, rail, air- and seaports and other infrastructure projects, mining, oil & gas, renewable energy, as well as retail, office and mixed use real estate developments, computer software projects and more general commercial matters including professional negligence claims.  He also uses that experience to assist clients in the drafting and negotiation of contracts.
