At HMS Cayman, we are committed to delivering a high quality client-focused service from the  beginning of every new client relationship and on an on going basis.

Our client portfolio has grown steadily since inception, ranging from wealthy individuals and their families, through to entrepreneurs, privately held companies, investment entities and large well known publicly quoted organisations.

Clients and professional intermediaries choose us because of the breadth of offshore experience we offer and the attentive and responsive service that is unique to HMS.

Our seasoned and knowledgeable team of professional staff provides practical guidance and forward thinking corporate and management solutions that our clients can rely on. We pride ourselves on our personal approach, professionalism, efficiency and flexibility.

From time to time clients have a need for additional requirements outside of our core services. HMS is part of an extensive professional network of quality service providers in the Cayman Islands (including lawyers, accountants and banks) that provide a comprehensive but independent service to clients. Working with professional intermediaries allows us to offer our clients a competitively priced “all inclusive” service. Many of our clients find that this "all inclusive" service is more convenient, efficient and straightforward than having to co-ordinate several service providers themselves.


Our Directors are practised professionals and long term residents of the Cayman Islands with excellent reputations and an extensive network of contacts within the industry.

We have over 60 years combined offshore financial services experience gained from leading offshore jurisdictions in Europe, the Americas and the Caribbean as well as in the Cayman Islands. This specialised expertise and wealth of knowledge is at the core of the corporate and personal services we offer to our clients.
