Aloha! 🌺 As we embark on our 30th year at CORAL, we’re thrilled to spotlight the dedicated teams leading the charge in coral conservation. First up, our Hawai’i team. In Hawai’i, coral reefs are the heart of culture, tradition, and environmental health. These reefs are crucial for the local economy and coastal protection, hosting an incredible array of marine life. Yet, they’re under siege from climate change, overfishing, and pollution. That’s where our team steps in.
For over 15 years, we’ve been all in, working tirelessly in Hawai’i to shield the reefs from pollution and advocate for cleaner, more sustainable wastewater systems. Our team embodies the spirit of malama i ke kai (caring for the ocean), crafting innovative solutions to protect these critical ecosystems and the communities that rely on them. So, let’s get to know the champions behind our efforts!
Manuel Mejia, Regional Program Director
Manuel is at the helm of our Hawai’i conservation efforts, mixing science with local know-how to do right by the reefs. He’s the proud owner of two master’s degrees—one in agricultural and biosystems engineering from McGill and another in environmental science and policy from Columbia. Manuel’s conservation journey has taken him around the world, from the Philippines to New York, and even aboard Hawaii’s traditional voyaging canoe, the Hokuleʻa.
- Favorite CORAL Memory: Getting to meet the team in person after starting with CORAL during the pandemic and diving with his teammates.
- Outside of Work: Manuel loves hanging out with his dog, hitting the tennis courts, cooking up a storm, and, believe it or not, jumping off mountains for a bit of hang gliding and paragliding fun – he’s done it with his family and even on his honeymoon!
I love that we get to integrate science and human dimensions of coral conservation in our daily work resulting in better outcomes for the communities we work with and the coral reef ecosystems we are caring for. I love seeing data-driven solutions making positive impacts for people and nature.Manuel Mejia
Makayla Rickard, Maui Nui Program Manager
Makayla is deeply committed to enhancing the sustainability of Hawai’i’s natural resources. With a bachelor’s degree in Sustainable Science Management from the University of Hawai’i, she’s tackled island sustainability and resource management head-on. Her experience ranges from conservation work in the Pu’u Kukui Watershed Preserve to marine environmental consulting, highlighting her versatile approach to environmental protection. Makayla has also lent her voice and expertise as a board member for Kipuka Olowalu, proving her dedication to her community.
- Favorite Part of the Job: Makayla thrives on CORAL’s strategy to build resilient coastal communities, which allows her to engage with the local communities she holds dear in Hawai’i.
- Outside of Work: Family time and beach days top her list of favorite things!
Supporting my community and coral reefs at the same time is a dream come true!Makayla Rickard
Erica Perez, Senior Program Manager
Erica is a true ocean guardian, armed with degrees in marine science and conservation biology from the University of Hawai’i at Hilo. For nearly two decades, she’s been diving into Hawaii’s environmental challenges headfirst, championing community-led solutions and fighting the good fight against wastewater woes to keep our reefs resilient. Leading the charge on the Clean Water for Reefs Puakō project, Erica’s been a key player in turning the tide, ensuring both our marine buddies and communities thrive.
But Erica’s passion doesn’t stop at Puakō’s shores. She’s a major force in statewide efforts like the State Cesspool Conversion Working Group and is all about keeping our groundwater clean and clear. With Hawai’i Wai Ola, she’s pioneered the first citizen science water quality gig in Hawai’i County, proving that when it comes to protecting our oceans, Erica’s not just talking the talk—she’s swimming the swim. Her work is a testament to her belief that together, we can make a big splash in safeguarding Hawaii’s marine life and ecosystems.
- Favorite Part of the Job: Erica’s favorite part of her job is being deeply involved in local climate initiatives and empowering communities with the science and data needed for positive change.
It’s incredibly rewarding to see our efforts in improving water quality translate into tangible, positive outcomes for both the environment and the local communities who depend on it.Erica Perez
Brian Kastl, Maui Nui Project Manager
Brian brings a world of experience to his role at CORAL, with a Master’s degree in stream restoration and sediment transport from the University of Hawai’i. His journey in conservation has taken him across the Pacific and Caribbean, where he’s applied his ridge-to-reef expertise to safeguard clean water for coral reefs. Brian’s work is deeply rooted in collaboration with local communities, developing coastal watershed management strategies that resonate with the needs and knowledge of those who call these places home.
He’s racked up some serious miles and milestones in aquatic conservation, working with big names like The Nature Conservancy, IUCN, Asian Development Bank, and even National Geographic. Whether he’s leading research dives, teaching courses, or developing projects that make a splash, Brian’s dedication to our oceans is as deep as the Mariana Trench. With his mix of serious science and a knack for collaboration, Brian’s making sure our coral reefs have a fighting chance.
- Favorite CORAL Memory: A standout moment for Brian was being on Moloka’i with the team, launching a drone to capture a traditional Hawaiian fishpond from above. Local kids gathered around, thrilled to see their heritage from a new perspective. This moment served as a powerful reminder of how ancient practices can inform today’s conservation efforts.
- Outside of Work: When he’s not leading conservation efforts, Brian finds balance and inspiration in nature, whether he’s hiking the ridges or catching waves on the reefs.
I love how highly supportive and dedicated my CORAL colleagues are!Brian Kastl
