Prof David Segal graduated from the University of the Witwatersrand in 1993. In 1997 he completed a residency in Pediatrics at the Cleveland Clinic, followed by fellowship training in Endocrinology at Riley Children’s Hospital in Indianapolis. Since returning to South Africa in 2003 he has practised in both the state and private sectors. This offered the opportunity to practice endocrinology and diabetes care in both extremely well and poorly resourced environments. He has also helped build an extremely successful diabetes telemedicine program operating in South Africa and abroad. Teaching is one of his driving passions.
