Samuel Agyei Wiafe is a senior clinical psychologist at Ga East Municipal Hospital and the Executive Director of the Rare Disease Ghana Initiative (RDGI), which he founded to address the lack of awareness, diagnosis, and treatment for rare diseases in Ghana. Inspired by his encounter with a family affected by an undiagnosed syndrome, he has become a key advocate for rare disease equity in healthcare.

He holds advanced training in Human Genetics and Genomics (NIH, USA) and Genetic Counselling (Wellcome Connecting Science, UK). He is an alumnus of the University of Ghana, and he is currently pursuing a PhD in Public Health at the Fred Newton Binka School of Public Health,
University of Health and Allied Sciences (UHAS) in Ghana.

He is a passionate advocate for equity, inclusion, and community engagement in healthcare, especially for individuals with congenital anomalies; rare and undiagnosed conditions; genetic disorders; chronic conditions and disabilities.
