About Three Oaks Consulting

Three Oaks Consulting helps organisations mobilise, govern, assure and deliver complex programmes.

We provide senior programme leadership, independent assurance and practical delivery support for organisations managing high-risk change, major investment and complex stakeholder environments.

Successful programmes need more than governance frameworks, reporting cycles and delivery plans.

They need experienced people who can provide calm judgement, practical leadership, independent challenge and clear decision support when delivery is complex or under pressure.

Three Oaks works closely with sponsors, senior responsible owners, programme teams and delivery partners to understand context, test assumptions and focus attention on what genuinely matters.

Our approach combines independent challenge with a clear understanding of delivery pressures, timelines and constraints. The aim is not to create additional process, but to support timely, well-informed decisions grounded in delivery reality.

Three Oaks Consulting brings senior programme leadership, mobilisation, governance and assurance capability to organisations delivering complex change.

The company’s work is grounded in practical experience across Combined Authorities, Local Government, central government, transport, regulated utilities, infrastructure and financial services.

Roles typically sit at the intersection of policy, delivery, governance and executive decision-making.

Stephen Wiseman founded Three Oaks Consulting after more than 30 years leading complex transformation programmes across the public and private sectors.

He works directly with executive sponsors, senior responsible owners and delivery teams to provide experienced programme leadership, independent assurance and practical delivery support.

His work focuses on helping organisations strengthen governance, understand delivery risk and make confident decisions when programmes are complex, high-profile or under pressure.

Clients engage Three Oaks when they need calm judgement, clear direction and an honest view of programme delivery.

Every engagement is different, but clients typically engage Three Oaks when experienced leadership, independent assurance or programme mobilisation capability is required quickly.

Support ranges from short advisory commissions through to longer-term interim leadership and assurance roles, always tailored to the scale, complexity and maturity of the programme.

The focus is simple: helping organisations make confident decisions and deliver successful outcomes.

Every organisation faces different challenges.
