Our Story
In 2002, amidst the beauty and tranquility of Samoa, OSM Consultants was born from the shared vision of Vui Sebastian and Shorley Mariner. What began in a modest home office, with a borrowed computer and a bold dream, marked the beginning of a journey shaped by purpose and possibility.
United by a common aspiration, Vui and Shorley envisioned a Samoa strengthened by resilient infrastructure and sustainable development, carefully woven together with the values of Samoan culture and community. Their vision extended beyond building a business; it reflected a deep commitment to contributing to the growth and future of their nation.
Driven by determination and purpose, they established OSM Consultants not simply as a business, but as a platform for advancing national development and empowering local communities. The company’s name reflects its strong family foundation: O for Olisana and Okalani, their cherished daughters; S for Sebastian and Shorley, the visionary founders; and M for Mariner, symbolizing legacy and continuity. Together, these initials represent their commitment to creating a lasting impact.
Guided by entrepreneurial vision and grounded in unwavering Christian values, Vui and Shorley laid the foundation for a company built on excellence, integrity, and service. OSM Consultants quickly emerged as a respected leader in Samoa, recognized not only for the quality of its services but for the values it upholds.
Over the years, OSM Consultants has grown into a symbol of innovation, continuously exploring new opportunities and delivering solutions that balance progress with Samoa’s rich cultural heritage. Its legacy is measured not only by business success, but by the meaningful and lasting contributions it continues to make to Samoan society.

Collaboration became the hallmark of OSM Consultants—a collective force of minds united to overcome challenges, create solutions, and celebrate success together. Leadership extended far beyond office walls, emerging through individuals who inspired others, nurtured potential, and cultivated the next generation of talent within the organisation.
Today, the values at the heart of OSM Consultants—excellence, innovation, collaboration, leadership, and integrity—continue to guide its journey forward. Their story reflects the power of resilience, vision, and faith, standing as a testament to what can be achieved through determination and the opportunities that exist within Samoa.
