Nat - Ground Asia Natarika Ngamwongwan (Nat)
Tour Director
GROUND Thailand

Working for GROUND is an amazing opportunity for me to put my experience into practice. As an undergraduate student, I joined a volunteer team to build a library and the foundation for a playground at a school in Nakhonratchasima, Thailand that was in rather dire straits . I felt something truly meaningful during the project and knew that I wanted to turn this experience into more than a memory while also knowing that I wanted others to feel what I had felt that day. As a GROUND Tour Director, my job is to design journeys and ensure a smooth operation before, during and after the journey.  I especially look forward to seeing my communities develop as more and more teams visit us.
