A Denver-based nonprofit focused on teen pregnancy prevention and youth sexual health will close its doors at the end of 2017 after losing two major grants.

Andrea Miller, executive director of Colorado Youth Matter, announced the news in an email to supporters Monday afternoon.

The organization, begun in the 1980s as a volunteer-run group, provides teacher training and assistance in picking sex education curricula for 10 to 25 Colorado school district a year.

Miller said she’s hopeful other organizations will pick up where Colorado Youth Matter leaves off – possibly RMC Health, the Responsible Sex Education Institute of Planned Parenthood of the Rocky Mountains or the state-run Colorado Sexual Health Initiative.

Colorado Youth Matter’s biggest financial hit came in July when federal officials announced the end of a major teen pregnancy prevention grant mid-way through the five-year grant cycle. That funding made up three-quarters of Colorado Youth Matter’s $1 million annual budget.

About the same time, the organization lost a family foundation grant that made up another 10 percent of its budget.

Miller, who took the helm of the organization just 10 months ago, said one of her primary goals was to diversify funding, but there wasn’t enough time.

Miller said with a variety of factors playing into the state’s teen pregnancy rates, which have been at record lows in recent years, it’s hard to say what the impact of the organization’s dissolution will be.

She said Colorado Youth Matter has worked successfully with school districts with different political leanings to find the right policies and resources to address the sexual health of their students.

“We have been masters at meeting the school districts where they are,” she said.
