RSVP Singapore The Organisation of Senior Volunteers is an Institution of Public Character and the National Centre of Excellence for Senior Volunteerism under the patronage of Mdm Halimah Yacob, President of the Republic of Singapore. Established in October 1998, our vision is to make every senior a volunteer. To achieve this, our mission is to develop senior volunteers and provide meaningful opportunities to serve the needs of the community. We currently have over 2,500 volunteers serving more than 200,000 beneficiaries each year including the mentally disadvantaged, at-risk children from low income families and socially isolated seniors through our community service programmes.
