Hoyos succeeds Julio Cesar Baldivieso. Baldivieso left his job after Bolivia's Copa America campaign, where they finished at the bottom of the group without a single point. He led 11 games and lost 10 of them.
Hoyos will train the team now for the South America World Cup qualifying which starts in September.
This is how the team welcomes the 53-year-old on Twitter and their hompepage:
"We welcome Mr. Angel Guillermo Hoyos as the new technical director of #LaVerde," a statement from the Bolivian Football Federation (FBF) read.
"With this selection we are confident in his ability, professionalism and we are confident we will get perseverance, effort and work all the way from the lower divisions, one of the many ways that meet the objectives we have.
"We feel that we have chosen the ideal person".
