The Treasure Coast runs on people who give a damn. Behind the beaches and boat parades, hundreds of nonprofits tackle real problems, polluted waterways, food insecurity, kids without mentors, and families in crisis.
Some organizations operate on multi-million dollar budgets with professional staff. Others run on volunteers and donated supplies. All of them need support, whether that’s your time, money, or both.
Here’s what’s actually happening in Martin, St. Lucie, and Indian River counties.
Environmental & Wildlife Conservation
The Treasure Coast’s coastal ecosystem attracts nonprofits focused on protecting what makes this region worth living in.
Florida Oceanographic Society
The Florida Oceanographic Society leads marine education and coastal restoration through its 57-acre facility on Hutchinson Island. They operate a sea turtle hospital, coastal research programs, and educational programs that teach thousands of people about ocean ecosystems each year.
📍 Location: 890 NE Ocean Boulevard, Stuart
🐢 Sea Turtle Hospital Tours: Daily 10 AM-4 PM
🤝 Volunteer: Weekly beach cleanups every Saturday at 8 AM
The sea turtle hospital treats injured and sick sea turtles found along the coast. Rehabilitation efforts focus on loggerheads, greens, and leatherbacks that wash up with injuries from boat strikes, fishing line entanglement, or illness.
Their coastal research programs monitor water quality, track marine species populations, and study ecosystem health in the Indian River Lagoon and Atlantic Ocean. The data collected influences local conservation policy and environmental protection efforts.
Education programs include summer camps (which fill up by February), school field trips, scout programs, and public workshops. The aquarium and nature trails showcase native Florida ecosystems and give visitors hands-on experience with marine life.
Summer camps, school programs, and public events connect people with coastal ecosystems in ways that actually matter. When kids understand what lives in the lagoon, they’re more likely to protect it as adults.
Captains for Clean Water
Captains for Clean Water fights for science-based water policy affecting the St. Lucie River and Indian River Lagoon. They mobilize fishing guides, boaters, and waterfront businesses to push for solutions to algae blooms and water quality disasters.
The organization gained national attention during toxic algae crises, putting pressure on politicians and water management districts to fix the problem instead of just talking about it. They focus on advocacy, education, and holding decision-makers accountable.
If you fish, boat, or care about keeping Treasure Coast waterways fishable and swimmable, this organization is worth following.
Rivers Coalition
Rivers Coalition focuses exclusively on St. Lucie River and Indian River Lagoon health. Their advocacy work influences regional water quality policy and local government decisions.
Community members credit this organization with pushing for science-based solutions during algae bloom crises. They track water quality data, testify at government meetings, and educate residents about what’s actually causing pollution.
Pelican Island Audubon Society
Pelican Island Audubon protects bird habitats across Indian River County. They manage the Oslo Riverfront Conservation Area and conduct monthly bird counts that contribute to national wildlife databases.
Their field trips take members to local birding hotspots, teaching identification skills while collecting data on species populations and migration patterns. The monthly programs cover topics ranging from backyard bird feeding to global conservation issues.
Team ORCA (Ocean Research and Conservation Association)
Team ORCA combines marine science with community action to protect the Indian River Lagoon. Based in Vero Beach, they conduct water quality monitoring, oyster restoration projects, and educational programs that get residents involved in lagoon health.
Their Lagoon Literacy Program brings hands-on science education to local schools. Students learn about lagoon ecosystems, water quality testing, and conservation through interactive classroom visits and field experiences.
Oyster restoration projects rebuild reef habitats that filter water and provide homes for fish and other marine life. Volunteers help build oyster mats, deploy restoration structures, and monitor reef health.
Water quality monitoring trains citizen scientists to collect samples, test parameters, and report data that tracks lagoon conditions over time. This grassroots approach fills gaps in government monitoring while engaging the community in conservation.
This is the organization for people who want to actually do something about lagoon problems instead of just complaining on Facebook.
Youth Development & Education
Treasure Coast nonprofits addressing youth needs have expanded significantly as the population grows and more families need support.
Boys & Girls Clubs of Martin County
Boys & Girls Clubs of Martin County operates multiple clubhouses serving hundreds of children annually. Their programs include STEM education, arts, sports, leadership development, and college prep support.

Boys & Girls Clubs of St. Lucie County
The St. Lucie County branch operates five clubhouses serving over 2,000 children annually. Their STEM lab at the Fort Pierce clubhouse features 3D printing equipment and coding instruction.
Parents consistently mention affordable after-school care as the primary draw, with programming running late enough for working families to pick up kids after their shifts end.
Big Brothers Big Sisters of the Treasure Coast
Big Brothers Big Sisters matches adult mentors with children from single-parent households. Their school-based mentoring program operates in 14 elementary schools across the region.
Wait times for matches average six months due to volunteer demand. If you’ve got time to invest in a kid’s life, this organization needs you. Background checks required.
Project LIFT
Project LIFT empowers youth through education, mentorship, and community engagement. They focus on breaking cycles of poverty and providing opportunities for kids who might otherwise fall through the cracks.
Programs include academic support, life skills training, and leadership development. They work with schools, families, and community partners to create comprehensive support systems for young people.
Hibiscus Children’s Center
Hibiscus Children’s Center provides residential treatment for abused and neglected children. This Stuart-based facility serves as a critical safety net when kids can’t safely stay at home.
The center provides trauma-informed care, therapy, education, and stability for children in crisis. It’s not glamorous work, but it’s absolutely necessary.
Food Security & Hunger Relief
Multiple nonprofits across the Treasure Coast work to make sure families don’t go hungry.
Helping People Succeed
Helping People Succeed addresses food insecurity through weekly distributions in Martin County. Their Jensen Beach warehouse processes 300,000 pounds of food monthly.
Regulars recommend arriving 30 minutes before distribution starts to access fresh produce before supplies run out. The organization serves agricultural workers, hospitality employees, retirees, and anyone struggling to afford groceries.
Harvest Food & Outreach
Harvest Food & Outreach serves St. Lucie County with food pantries, job training, and eviction prevention assistance. Their statistics show 40% of clients are employed but still struggle with housing costs.
The organization partners with CareerSource Research Coast for workforce development programs. They understand that hunger isn’t just about food—it’s about wages, housing costs, and economic opportunity.
Treasure Coast Food Bank
Treasure Coast Food Bank operates as part of the Feeding Florida network, distributing millions of pounds of food annually across Martin, St. Lucie, and Indian River counties.
They partner with local pantries, churches, and community organizations to get food to people who need it. The warehouse in Stuart serves as a regional distribution hub.
Volunteer shifts include sorting donations, packing food boxes, and loading vehicles for distribution sites. It’s physical work, but it directly helps families eat.

Medical nonprofits fill gaps in healthcare infrastructure, particularly for uninsured and underinsured residents.

The organization reported 28,000 patient visits in 2023. They provide care to people who would otherwise end up in emergency rooms or go without treatment entirely.
Coastal Community Foundation
Coastal Community Foundation distributes grants to smaller health-focused nonprofits throughout the region. Since 2019, they’ve funded mobile dental clinics, mental health crisis response teams, and diabetes prevention programs.
They connect donors with community needs, matching philanthropic dollars with organizations doing effective work.
Social Services & Crisis Support
Multipurpose social service nonprofits address poverty, homelessness, domestic violence, and crisis intervention.

Tykes & Teens provides emergency clothing, school supplies, and holiday assistance for children in foster care or protective services. The Port St. Lucie organization relies entirely on donated items and operates through a network of 200+ volunteers.
When a child gets removed from an unsafe home, they often leave with nothing. This organization makes sure they have clothes, school supplies, and basic necessities.
United Way of Martin County
United Way of Martin County funds and coordinates multiple social service programs addressing education, financial stability, and health. They vet local nonprofits, distribute funding strategically, and measure outcomes.
Their annual campaign raises money that gets distributed to vetted organizations doing effective work. They also run volunteer programs connecting people with opportunities across the county.
Do You Give A Ruck
Do You Give A Ruck supports veterans, first responders, and their families through rucking events (hiking with weighted backpacks) that build community while raising funds for mental health and suicide prevention.
The organization addresses veteran suicide, PTSD, and isolation through physical activity, peer support, and connection. Events bring together vets, active military, first responders, and civilians who support them.
It’s a different approach to veteran services, less talk, more action, and real community building.
Arts, Culture, and Historic Preservation
Cultural nonprofits preserve local heritage while supporting working artists and providing community gathering spaces.
Vero Beach Museum of Art
Vero Beach Museum of Art anchors Indian River County’s visual arts scene. Their permanent collection focuses on 20th-century American art with rotating exhibitions featuring regional artists.

🎟️ Free Admission: Second Saturdays

Patron reviews consistently highlight acoustics and sightlines across all 574 seats. The theater brings professional-quality performances to Stuart without requiring a drive to West Palm Beach.
Elliott Museum
Elliott Museum chronicles Treasure Coast history through permanent exhibits on maritime heritage, baseball spring training legacy, and pioneer settlements. The facility underwent $7 million in renovations in 2013, funded by philanthropic donations.
The museum preserves regional history that would otherwise disappear as development changes the landscape.
Animal Welfare & Rescue
Local animal-focused nonprofits operate independently from county-run shelters, offering specialized services.
Furry Friends Adoption & Clinic
Furry Friends provides low-cost veterinary care alongside adoption services in Jupiter and Stuart locations. Their voucher program subsidizes spay/neuter surgeries for low-income pet owners.
Community feedback emphasizes same-day appointments for urgent care needs. They fill the gap between county animal control and expensive private veterinary clinics.
Totally Fetch Animal Rescue
Totally Fetch Animal Rescue focuses on saving dogs and cats from high-kill shelters, providing medical care, and finding them permanent homes. Based on the Treasure Coast, they pull animals from overcrowded facilities where they face euthanasia.
The rescue operates through a network of foster homes rather than a central facility. Foster volunteers provide temporary care while animals receive veterinary treatment, behavioral assessment, and socialization before adoption.
They handle medical cases other rescues can’t afford—dogs needing surgery, puppies with parvo, cats with upper respiratory infections. The organization covers veterinary costs and rehabilitation so animals get a real chance at adoption.
Adoption events happen regularly at local pet stores and community gatherings. The rescue matches families with dogs and cats based on lifestyle, experience, and what the animal actually needs rather than just what looks cute.
Hobe Sound Wildlife Refuge & Nature Center
Though technically state-managed, Hobe Sound Wildlife Refuge partners with nonprofit groups for sea turtle monitoring and beach preservation. Volunteer opportunities include nest surveys during May through October nesting season.
