From 'angry grandmas' to lemonade stands: How grass-roots groups stepped in to help separated families

Yeni Gonzalez, a Guatemalan mother who was separated from her three children at the US-Mexico border, center, is embraced by volunteers after being driven cross-country to see her children for the first time in weeks.

(CNN)Grandmas arrived at a Texas bus station toting backpacks stuffed with supplies. Groups of moms planned cross-country carpools. Shelters opened their doors to families in need.

The administration's now-reversed "zero tolerance" policy, which led to the separation of thousands of parents and kids at the border, spurred a wave of grass-roots groups that organized across the country.
Their mission: stepping in where they felt government officials had failed.
And in the days leading up to Thursday's court-ordered reunification deadline, their efforts were on full display. Here are some of the things we saw:

    'Angry aunts and grandmas' brought backpacks stuffed with supplies

    At a bus station in the border city of McAllen, Texas, this week, a group of volunteers arrived with backpacks full of toiletries, bottled water and snacks. The group, known as Angry Tias & Abuelas (Angry Aunts & Grandmas) of the Rio Grande Valley, said they wanted to help families who had just been reunited and released from custody.
    "These people don't have a cent in their pocket," said Melba Lucio, an English instructor who joined the effort.
    "We're angry, but we're not staying angry," Lucio said. "We're doing something about it. We're calling our friends."
    They organized swiftly to amass and distribute supplies, she said.
    "We didn't even know each other, a lot of us," she said. "We meet, two or three days, and we're like family. We're all trying to do the right thing as human beings."
    After the group was asked to stop handing out supplies at the McAllen bus station, volunteers instead delivered them to a Catholic Charities shelter nearby. Then they returned to the bus station to field questions and help families coming through navigate their next steps.
    "We are just citizens that want to help and do the right thing," Lucio said.

    Moms formed carpools to take people across the country

    A network of volunteers known as Immigrant Families Together has used crowdfunding to raise more than $300,000 to help pay bond for parents in detention. The group, largely made up of mothers, also has organized cross-country carpools to transport immigrant families and host them in their homes.
    In addition to forming carpools to help with transportation, Immigrant Families Together has raised money to help more than a dozen immigrant mothers pay bond.
    Julie Schwietert-Collazo said she started the group after hearing about one woman's case on a radio show.
    "I saw that it was possible to have an impact through the collaboration of many people, and I knew that there were a lot of people who wanted to commit themselves to repairing the pain toward immigrants that we have caused as a country," she told CNN en Español.
