Teresita Quintos-Deles was President Gloria Macapagal Arroyo’s presidential adviser on the peace process from 2003 to 2005. She spearheaded several non-government organizations (NGO)'s concerning women's rights and advocacies. Since 1981, Mrs. Deles has maintained an active involvement in the women's movement particularly in the institution of PILIPINA, which is recognized as the first women's organization in the Philippines to espouse an explicitly "homegrown feminist" line. PILIPINA claims its primary constituency among women development workers and operates with autonomous chapters in the National Capital Region and nine provinces spread throughout the country. PILIPINA led the formation of Abanse! Pinay, which was one of only thirteen parties which garnered the required number of votes in the first party-list elections held in 1998. She has also been the co-founder of the Coalition for Peace, the Philippines' first citizen's peace formation to emerge after the 1986 People Power uprising.
