Short-term teams go for a week or two to work alongside churches and ministries DOVE already knows. You do not need to be an expert in anything. You do need to be willing to serve and be flexible, and to get a recommendation from your pastor.
Teams open and close through the year. Past teams stay listed here because they are the clearest picture of what going actually involves.
Each team has its own link to apply on its page. If none of these suit you, the people already serving long term are the other way in.
