About Oak Group

Originally formed in 1999, Oak Trust in Guernsey consolidated with Consortia Partnership in Jersey, Kreston in the Isle of Man and IAG in Guernsey since 2018, forming what is now Oak Group.

Since its founding in 2018, Oak Group had been majority owned and funded by the Guernsey listed Financial Services Opportunities Investment Fund Limited (FSOIF). FSOIF was managed by Ravenscroft Specialist Fund Management Limited, who played a pivotal role in guiding the group’s early development and fostering the open, client-centric culture that Oak boasts today.

In late 2023, Oak Group received new strategic investment through FSOIF from Pula, the family office of long-time Guernsey resident Stephen Lansdown. Following regulatory approval in March 2025, Oak completed its transition to private ownership under Opera— a holding company majority backed by Pula, with additional support from like-minded partners such as Sealyham, the family office of Tom Scott. This new ownership structure is designed to drive long-term, sustainable growth and build a portfolio of global businesses.

Today, Oak Group operates across Guernsey, Jersey, Isle of Man, and Mauritius, with more than 230 employees administering over £19 billion in assets. The group is known for its client-centric approach, commitment to excellence, and forward-thinking vision. Under the leadership of Kim Sgarlata, Oak embarks on a transformative journey of organic and inorganic growth, investing in its people, processes, technology, and data to establish itself as an industry-leading global fiduciary, corporate, and fund administration business.
