A New Partnernship with YouthBuild

YouthBuild is a six month job training pre-apprentice program for young adults ages 18-24. The program offers GED/HSD completion, case management support, employment readiness skills, and pre-apprenticeship training. After students graduate they receive 12 months of follow-up from their case manager to continue to help support them in achieving their goals, including to place students in apprenticeship programs in the trades. JayMarc Homes & the Parks & Recreation Department is proud to have Youth Builders on site at the adventure Playground this summer helping with our young builders.
