Margareth Awiti – President 


Margareth Awiti was born in Tanzania and came to the United States in 1996. She lives in the Wynnefield neighborhood of Philadelphia and works as a nurse at the Inglis Foundation. For years she has personally assisted family, friends and former neighbors with medical emergencies, school fees and housing needs. She has long been interested in developing a larger outreach program to help people in Tanzania. She hopes for people in Philadelphia to get to know the wonderful people and famous natural sites in Tanzania. The objectives of the Philadelphia-Serengeti Alliance have grown out of her own experience of life in Tanzania, where as a nurse midwife she encountered many individuals, especially women and children, who were and still are deprived of human rights, clean water, education, economic well-being and health care. In 2010 she launched an effort at St. Peter’s Church that has grown into the Philadelphia-Serengeti Alliance.
