Leigh Pasqual, 

Leigh has spent more than a decade working on women’s rights issues as a writer, communications strategist, and gender advocate. She has worked with the United Nations and with nonprofit organizations in the United States and other countries on issues such as CEDAW, violence against women, gender and HIV/AIDS, reproductive rights, and effective communication in the development field. Leigh has long been inspired by the work of OWP’s Founder and Executive Director, Joanne Derwin, and is particularly drawn to the organization’s mission. “I love the emphasis on curiosity about and respect for other cultures,” she says. Leigh holds a degree in European Studies from the National University of Singapore and a Master Degree in European History from St. Antony’s College, Oxford University. She continues to consult with organizations on a broad range of development issues, and is the founder of a non-profit organization - Good for Girls - dedicated to empowering girls and supporting their education.

Originally from Singapore, Leigh has been living in New York City for just over 10 years with her husband Jesse, her two little girls, Tessa and Ella, and their dog Otis.

Margarita Peces,

Margarita holds a Bachelor’s Degree in Advertising and Public Relations.  Her love for graphic design soon landed her in New York where, while continuing her advertising and design work, she took the opportunity to enroll in workshops with some of the most outstanding professionals in the field, such as Milton Glaser and David Carson. Marga has participated in the creation of over 40 TV commercials, as well as many print and digital campaigns. Her work has garnered important awards, among them an Addy, an ANA Multicultural Award, and an Effie.  Currently, she works as a Creative Director for an advertising agency specialized in wellness and health. Margarita was first drawn to OWP when searching for a school for her own son, Leo. In OWP she found “a great school where my son could learn Spanish without even noticing because he enjoyed school so much, a school that shares my values in education, community, and culture.”

Originally from Madrid, Spain, Marga now lives in New York City where she enjoys exploring her passions: her family, traveling, and constantly exploring new paths to knowledge and fresh ways of thinking and expressing herself.
