Olin Simplis
The Guard Whisperer
Belize to Los Angeles. 30+ years of earned authority.
Olin Simplis is not just a trainer. He is a development architect. His work sits at the intersection of skill, psychology, biomechanics, character, and pro-level preparation — built across three decades of work with NBA professionals, WNBA champions, NCAA standouts, and elite prep talent.
Born in Belize and raised in Los Angeles, Olin developed a philosophy that treats basketball development as a total pursuit: not just mechanics and film, but mindset, accountability, and the discipline required to sustain a pro career when the lights get loud.
His private training environment, The Dojo, is a standards room — not a content gym. Every rep is designed to build the player behind the prospect, the character behind the talent, and the habits that hold under the pressure of the highest level.
