Telile (Lily) Yoseph, Founder

A native of Ethiopia, Telile Yoseph (known to most as simply Lily)  Studied tourism in Holland, where she spent thirteen years.  In 1993 she moved to Los Angeles, California and received a degree in Fashion Merchandising.  In 1997 she moved to the Bay Area and became a real estate agent.  Her career was no longer fulfilling. That is when she took some time off to reflect and find a new purpose in her life.  Lily finally found her true calling during her first trip back to her home country after being away for over twenty-five years. During her visit to her home country, she was deeply touched by the overwhelming need of children and families.  A young girl named Ubo, who had suffered many hardships but still hoped for a better future, particularly moved Lily.

Lily made a commitment to send this remarkable young girl to school, a decision that changed both Lily and Ubo’s lives forever, and gave birth to the vision of Tangible Hope. Lily strongly believes that working together we can make a difference in the lives of many more girls like Ubo to realize their dreams and full potential.

“Kids are innocent. They have no political or religious opinions. If I see children in need, I want to help them. No matter where they are. No matter who their family is.” Lily Yoseph

She has now fully dedicated her life to the cause of Tangible Hope, making a lasting difference and giving girls like Ubo tangible hope through education and empowerment.
