Oak is privately owned by Opera Limited, a holding company majority owned by Stephen Lansdown CBE, with additional support from like-minded partners such as Sealyham, the family office of Tom Scott.

Opera was created to reimagine fund, corporate and fiduciary services, bringing together independent firms that share a commitment to people, purpose and long-term value – supporting them with strategic capital, operational expertise and cultural alignment.

Oak operates across Guernsey, Jersey, Isle of Man, Mauritius and The Bahamas with more than 250 employees administering over $24 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.

We strive to create an environment where our people are cared for, enabled, empowered and supported. We prioritise the continuous growth and development of our people, recognising that their success is the foundation of our excellent service and our shared prosperity.
