Our history

MasonBreese was founded by Swithun Mason and Vernon Breese on 25 May 2011. Our focus from the start has been about providing forward thinking expertise in our consultancy services.

We began working with a small number of banks in Jersey and before long we had grown our client base attracting talented consultants to join the team and grow our expertise out from financial services to reflect the diverse market here in Jersey. Our client base today includes businesses in the public sector, arms-length publicly owned enterprises, banks, intermediaries, retail, utilities, charity and intellectual property management sectors.

From day one our focus has been on training and building a team driven by our core values. As we have grown and matured we are proud that our focus has remained the same and our talented team of consultants demonstrate this every day.

In 2020 a new board of Directors joined MasonBreese and a renewed programme of investment in people, premises, infrastructure, community and in growing local talent was implemented. Sustainability in particular has been a key consideration as the business has continued to grow.

As a test of our Environmental Social and Governance credentials MasonBreese has applied for B Corp accreditation. We believe that this the highest level of externally audited Environmental, Social and Governance accreditation available for “for profit” enterprises. We have learnt a huge amount from the process so far and it underlines our commitment to strive to grow our business in line with our values.


Our people are what make our business a success. Be part of a supportive team where everyone is encouraged to contribute their thoughts and views to help deliver excellence in change and transformation across a variety of sectors and jurisdictions.
