Who we are

Maurice Aroesti - Group Chief Executive

Maurice joined us as a Project Manager on an insurance assignment; over 30 years on he leads OCS both in the UK and Europe. He has retained a strong interest in the insurance domain and oversees OCS' joint business service venture for the commercial insurance market. Maurice also introduced Net Promoter Score to OCS in 2007 as part of the client-centric strategy. And he still does some high-level consultancy - so he knows precisely what it is to be a working consultant.

Brick Du Bourg - Services Director

Joining OCS as a database analyst over 30 years ago, Brick's first assignment was implementing electronic messaging, which at that time was a complex task. His knowledge of software engineering methodology and his ever-expanding technical skills have allowed Brick to lead OCS' delivery teams both as Project Manager (Atern and PRINCE2 qualified) and Programme Director. He has also served as an interim IT Director and as a Development Director for OCS' clients. His structured, reasoned, empathetic and pragmatic approach ideally places him to oversee IT service delivery.

Richard Williams - Service Delivery Director

After enjoying the challenges of working for a global energy company, Richard decided to seek out a place where he could involve himself more closely in operations. Taking over OCS' infrastructure 25 years ago, he transformed the service model to cope much more effectively with a broad spectrum of client infrastructure requirements. Today, he has a combined role of Project Manager and Operations Manager, looking after a number of our well-established clients.
