Born in Rotterdam, The Netherlands, Manon Rinsma-Leonard, MSc, graduated in Amsterdam with a Masters in Media Psychology. Trying to compensate for the loss of her mother as a result of glioblastoma, Rinsma wanted to work for prominent international events organizers, world-class commercial brands, a broad range of global entertainment companies, and several governmental institutions. In 2015 she started a year-long journey around the globe. During her travels she found the inner strength to write a book to share her personal, heartbreaking, experience with the world.
After moving to Southern California, and the publication of her book "13 Diamonds – Life Before Death from a Child’s Perspective," Rinsma founded "Stronger by Sharing"
a 501 (c) 3 organization focusing on helping others gain strength from the experience of others. Her mission is to provide hope for people in difficult times by initiating openness, sharing stories and creating an inspirational environment. Her goal is to help people "become an ambassador of their life rather than being a victim of (bad) circumstances."
