The American Chamber of Commerce in Thailand (AMCHAM) is the leading international business association in Thailand.

AMCHAM creates positive impact in the Kingdom of Thailand through capacity building, advocacy and networking for our members.

AMCHAM is an independent, non-partisan, non-profit organization. We maintain collaborative relationships with the U.S. Embassy Bangkok and affiliated U.S. government institutions. AMCHAM is also a member of the Board of Trade of Thailand (BOT), and liaises regularly with different ministries in the Royal Thai Government. We are active regionally through the AmChams of the Asia Pacific (AAP) and in the U.S. as an accredited member of the U.S. Chamber of Commerce.

Jeffrey Nygaard
AMCHAM President & Executive Vice President of Operations & Technology Seagate Technology

Jeff Nygaard leads the global operations and technology team at Seagate, with over 36,000 people who speak nine languages and live on three continents. He started working at Seagate as an engineer. As he progressed, he has had the opportunity to live and work in the U.S., Asia, and Europe, developing global perspectives, but connecting locally on a personal level. During his tenure, he has been instrumental in building high-performance teams, integrating a competitor's business, developing strategic alliances, and reorganizing Seagate for the future. Nygaard reflects Seagate's philosophy and culture that a responsible business -one that treats people, the environment, and our community with respect- enables better results. Previously, Nygaard has served twice as the President of the American Chamber of Commerce in Thailand and as an honorary AMCHAM board advisor. He holds Bachelor's and Master's degrees in Mechanical Engineering from the University of Minnesota, with a focus on Robotics and Control System Design.
