TNN Beauty Santee operates a California Board of Barbering and Cosmetology–approved cosmetology and barbering school on Woodside Avenue, running an apprenticeship program established in 2011. Apprentices earn a temporary two-year license while completing supervised floor hours in the same building complex that houses LK Nail Salon and several independent beauty suites. The program holds VA approval for GI Bill tuition payments and accepts transitional funding through the San Diego Workforce Partnership, expanding access for veterans and career-changers across East County. Additional TNN campuses in Oceanside, Lemon Grove, and Poway extend the same apprenticeship model across four San Diego County locations. Salon-side services at the Santee campus range from precision fades and balayage to corrective color, complementing the body-waxing and esthetic treatments at Beautifully Bare SD one suite over on Woodside Avenue. Each apprentice logs between 144 and 320 classroom instruction hours alongside 32 to 42.5 weekly hours of supervised on-the-job training before sitting for the California state board licensing examination.
