Sekou Soumah (Derrell Walker)
African Dance Instructor

Derrell “Sekou Soumah” Walker is a Portland, Oregon native and a strong presence in the West African Drum and Dance community. He is the perfect blend of drum and dance; Western and West African. He effortlessly inhabits the highest levels of Mandingue drum and dance, and blends these skills with his American roots and a deep knowledge of the Mandingue culture.

The embodiment of these traits combined with a natural gift for teaching and mentoring make Sekou one of a kind. Africans and non-Africans alike respect him worldwide. This is reflected in Sekou's starring as both a dancer and a percussionist in Moustapha Bangoura's Tinkanyi instructional dance videos in 2003. In 2004 Sekou received his teaching certification from Mamady Keita and Tam Tam Mandingue, followed by a teaching diploma in 2008.

Sekou began his dance career in 1998, after several years of training as an athlete. The path from athlete to dancer is an unusual one. As a result of thousands of hours spent training and competing in track & field and baseball, Sekou possesses a grace and power in dance that is rare, particularly amongst American-born African dancers. Sekou continues to refine these skills through performing and teaching dance all over the United States and internationally in countries including Scotland, Singapore, Mexico and Bali.
