The Team

Douglas Johnstone

Finance Director

Doug is a Chartered Accountant who, after spending several years with one of the “Big Four” accounting firms, moved into finance controller and director roles with large manufacturing companies before establishing his own financial consultancy business.  In 1995 he was one of the founders of a financial services company which grew to become one of the most recognised names in the sector and was acquired by a large group.  Thereafter Doug acted as finance director for many owner-managed businesses in a wide range of sectors and, after working with Mark at C2, joined with him to establish Rockwood Composites.

Mark Crouchen

Managing Director

Mark is a recognised expert in composites with over 30 years’ experience in the industry, providing composites solutions into a wide range of industries including aerospace, defence, medical and nuclear.  He is an exceptional engineer whose early career with multinational organisations specialised in flight control and launch systems.  He is an entrepreneur with the rare combination of skills that enables him to build companies which can supply innovative but practical and cost-effective solutions to complex engineering problems and, having previously founded 2 successful companies (Carbon Design and C2 Composites), he established Rockwood Composites in 2010.

Silvan Roberts

Operations Manager

Silvan has always worked in customer-facing roles.  She started out in front-line sales, rising to team leader and account manager, working in a wide variety of industries.  Her responsibilities developed over time into wider customer service roles.  In 1999 she joined C2, initially in a sales role, but this grew into the full range of office duties including purchasing, accounts and administration.  Although not a technician, she has developed an in-depth knowledge of the composites industry.  In Rockwood, she is responsible for the full administration function including customer account management, purchasing and scheduling.

Derryck Morton

Engineering Manager

Derryck considers himself fortunate to have done his HNC level mechanical engineering apprenticeship with the Atomic Energy Research Establishment, which is widely considered to have been one of the best available.  Thereafter he worked as a machinist, programmer and designer with a precision engineering company which specialised in components for the Formula 1 and space exploration industries.  He joined C2 as Engineering Manager in 2000 and now fills the same role with Rockwood.  He specialises in CNC programming and machining and, with over 40 years’ experience, has unrivalled expertise in problem solving, product design and production support.

Mark Drinkwater

Product Quality Manager

Mark has always worked in an engineering environment.  He has an HNC in Mechanical Engineering following a 5 year apprenticeship with a long-established manufacturer of turbines and power generation equipment.  After broadening his experience through a range of assignments in Europe, he returned to the same company as a senior CAD production engineer and followed this with several years as a toolmaker for a precision engineering company.  It is this wide range of experience and skills gained over more than 25 years that gives Mark the necessary background to fulfil the demanding quality role within Rockwood.
