Often times a school will have service scholarships. My daughter has one at College of Charleston. She was a finalist for one at Colorado b4 she withdrew her application.
So taking a step further. Find the right school. You might then find within that school opportunities to serve and get paid. My daughter is leading a club to help the refugeee resettlement effort in her city.
I think most ‘holistic’ schools like to see service or other ‘extras’. But I think many will also provide a continued opportunity to serve.
