About
Jason is a Director in the Central London Office Markets (CLOM) team at JLL, Jason specialises in advising landlords and developers on strategic development and leasing initiatives across London's prime commercial districts.

Beyond his client work, Jason serves as the current Chairman of the City Agents Society, a vital institution functioning as the central marketplace where all property availability and requirements are communicated amongst agents. This not-for-profit organisation, to which every agent in London subscribes (either the City or West End division), fosters collaboration within the commercial leasing community while also raising substantial funds for worthy causes.

He consistently integrates technological solutions into his approach, streamlining processes and enhancing the quality of service delivered to clients. This forward-thinking mindset, combined with his extensive market knowledge, enables him to provide landlords and developers with strategic insights that maximize the potential of their assets in London's increasingly tech-driven commercial landscape.
