Trish Collins


Contact: +44 7768 012 641

Trish founded Exchange Consulting 30 years ago to specialise in the commodity trading arena. Since then, she has developed an unparalleled network across revenue generating functions including sales, trading & operations within the oil, gas metal and agriculture sectors. Trish has an in-depth understanding of players in the market, its operational culture and management styles. She is passionate about ensuring that the role is not just a functional fit for the candidate, but that it's well aligned with her or his long-term values and aspirations - to increase the job satisfaction for the candidate; and raise employee engagement level for the employer.
Trish’s dream is, one day, to get on a train (preferably one that runs on time), look around and see people smiling on the way to work, excited about what they do and who they work for.
