Sierra West

Sierra West provides financial, economic and management consulting services to clients in the public and private sectors. Our focus is on the energy, water and environment markets.

Sierra West was established in Vancouver, Canada in 1995. In 1996, we established an office in Bangkok, Thailand. Today, our primary base of operations is Bangkok. This gives us easy and cost effective access to the entire Asia - Pacific region.

With a direct and permanent presence in Asia for 15 years, we've gained an extensive knowledge of the region. This has given us a deep understanding of the key issues that determine project success in this region.

Committed to Excellence

Since 1995, we've established a reputation with our clients for excellence in our work. Our clients can rely on us for quality work, completed on schedule, and within budget.

One of the greatest strengths that we can bring to a project is our comprehensive knowledge of the project appraisal procedures and requirements of the World Bank and Asian Development Bank.

We've undertaken over 50 projects for the World Bank and ADB so we understand exactly what these agencies need to make their projects successful.

Sierra West is a registered consulting firm with both World Bank and ADB.
