Info is a registered 501(c)3 tax-exempt non-profit organization in California, USA, dedicated to supporting the practice, study and teaching of Buddhist Insight (Vipassana) Meditation, in the tradition of Ajaan Tong Sirimangalo. The organization was founded by Brother Noah Yuttadhammo, an ordained disciple of the venerable Ajaan Tong in order to help facilitate the spread of Vipassana meditation around the world.

  • Brother Noah Yuttadhammo – President
  • Alfonso De Rose – Vice President
  • Navarat Thananopavarn – Treasurer

Apart from this core group of official staff, many volunteers too numerous to mention help to make our work function smoothly, and are coordinated by the core members listed above. Persons wishing to volunteer should contact us through the Los Angeles contact form.
