Ms. Lorsermvattana is Director at the Thai Medical Error Network-TMEN. She was born in 1963 in Chiang Rai province. Her father was a farmer and her mother a food vendor. Ms. Preeyanan began to recognize the power of organizing stakeholders into a single unified voice to speak out against systemic problems while still in secondary school. Ms. Preeyanan enrolled at Payap University near Chiang Mai province, and studied business administration. After obtaining her BA degree, she moved to Bangkok to explore new career paths. She attended a MA program in England; however, she was forced to leave her full-time studies for work, to provide for her aging parents in her village. She returned to Thailand and managed a family business with her husband. In 1991, Ms. Preeyanan gave birth to a son who fell ill shortly after birth due to an allegedly mishandled delivery and subsequent medical neglect. She began a decade-long legal struggle to bring about justice for her son, uncovering the many legal and policy hurdles which protect the medical profession at the expense of patients’ rights in Thailand. She formed TMEN in 2002 to use her personal experience to help other victims seek justice and create policy changes to enshrine patients’ rights into Thai law.
