Volunteer We rely on our volunteers to support all aspects of our work. Volunteering with CASA UK provides volunteers with training and experience (our volunteers often move on into further training or employment) or away to put your existing skills and knowledge to good use. Join our volunteer team Volunteers support all aspects of our work. Joining our team can give you the opportunity to learn new skills, use the skills and experience you already have, access training and development opportunities, join a fantastic and committed team and get to know and share experiences with our clients. We would be happy to hear from you if you are interested in joining us and are able to make a regular commitment.
