Growing up in Kenya, Ken's dad had 2 wives. Nsimbi had 9 siblings. His dad, a dentist was an outgoing and gregarious fellow who had a full and lively life. Moving to Seattle to share a 1-bedroom apartment with 3 brothers, in the US was a hard transition, "It felt like a downgrade." "When I look back, my mom's decision to bring us to the US was the best thing ever."
