At Mitraphap Hospital in Bangkok, she learned therapeutic massage. For the ancient Eastern technique of balancing the body's organs by pressure to different points on the soles of the feet, Khun Oppawan turned to the Foot Reflexology Association of Thailand.
After more than a dozen years in Bangkok, Khun Oppawan was ready to return to her home. With the help of an architect friend from Bangkok, and the skills of her father and his island neighbors, she built a gracious complex of thatched buildings of local bamboo, wood and stone, set in an organic garden of herbs, flowering trees and flowers.

Today Khun Oppawan offers a full range of massage and herbal treatments, and a variety of herbal health and beauty aids prepared by Khun Oppawan and colleagues in traditional well-being around Thailand
