St. Marlo & Co.

About

Who we are

An independent consultancy built on established experience

St. Marlo & Co. is an independent client-side project and program management consultancy, specialising in delivery across the full project lifecycle.

With experience across construction, consultancy and client-side delivery, we partner with government and private sector clients. We predominantly deliver projects across education, health, sport & recreation, specialising in leading end-to-end delivery or providing targeted expertise that integrates seamlessly with existing teams and programs.

Experience across both sides of delivery

St. Marlo & Co. provides a practical understanding of how projects are planned, procured and delivered from different perspectives — supporting a balanced approach that combines technical knowledge, commercial awareness and an understanding of the pressures faced by clients, consultants and contractors.

From complexity to clarity

That perspective spans public and private sectors and every stage from early strategy through to handover — so every decision reflects site realities, budget discipline, and enduring operational needs, resulting in a clearer path from ambiguous early decisions to a confident, well-documented handover.

How we deliver

The right capability, at the right time

St. Marlo & Co. combines principal-led leadership with experienced project professionals across project management, superintendency, contract administration, commercial management and project controls.

Project teams are shaped around the needs of each engagement, allowing capability to scale while maintaining consistent leadership, clear accountability and senior involvement.

Experience Behind St. Marlo & Co.

Established experience. New consultancy.

Before establishing St. Marlo & Co., Cindy delivered projects and major capital works programs through previous employers and client engagements across construction, consultancy and client-side environments, building the depth of experience that now informs how St. Marlo & Co. approaches project delivery.

Cindy Deayton, Managing Director, St. Marlo & Co.

“I founded St. Marlo & Co. to build a consultancy grounded in the values that have shaped my career—honesty, accountability, integrity, and genuine care for the people and organisations we serve. After years delivering major capital works programs, I saw how profoundly clients benefit from a partner who is both technically strong and personally invested. St. Marlo & Co. brings that balance to every engagement. We show up, we listen, we solve problems, and we stay until the job is done properly. Our work is built on trust, relationships, and a commitment to excellence, with the belief that great project management doesn’t just deliver projects—it transforms the experience for everyone involved.”

How we navigate

Our North Star

We strengthen the weak links

A project is a chain of people, trades and decisions. We all succeed when weak links are found and made stronger — and we all fall short when they’re left unaddressed. Our North Star is a single fixed point: the best outcome for the project and everyone invested in it.

Every day · in practice
  • Are today’s actions moving the project forward?
  • Are risks, responsibilities and decisions clear?
  • Is the team focused on the priorities that matter most?
Every decision · strategically
  • We define project success early and keep decisions aligned to it.
  • Governance, procurement and risk are considered against the project’s broader objectives.
  • Where priorities compete, we bring the discussion back to the agreed outcome.
