Be the first to learn about volunteer opportunities with Groundwork Denver! Due to COVID-19 restrictions, we are limiting the number of volunteers at each event and requiring registration. Due to a City and County of Denver public health order, all volunteers must be fully vaccinated against COVID-19 in order to participate. Boosters are not required at this time, but are heavily recommended. All volunteers will also need to sign a Liability Waiver prior to their first volunteer event.
