Who We Are & Where We Come From
A Boston-based nonprofit born from community need, cultural heritage, and an unshakeable belief that every person deserves the tools to thrive.
Built on Community, Driven by Purpose
Green Castle Hill Group, Inc. is a Boston-based nonprofit organization built on a singular belief: every person deserves access to tools, resources, and community support to thrive.
Founded with deep roots in Boston and inspired by a global vision of healing, equity, and sustainable growth, GCH bridges urgent community needs with meaningful long-term solutions.
From environmental challenges to gaps in mental health care, affordable housing, and economic opportunity — we show up, listen, and act.
Rooted in Antiguan & Barbudan Heritage
At the heart of GCH is a commitment shaped by both lived experience and cultural legacy. Our founder’s deep connection to Antigua and Barbuda influences every program we run with cultural sensitivity, global perspective, and justice.
The same systems that fail communities in Boston often fail communities in Antigua. Solving those systems requires working together.
That heritage drives us to see beyond borders: creating scholarship opportunities and educational exchanges that empower individuals from the Caribbean alongside our neighbors in Mattapan, Dorchester, and Roxbury.
By uniting advocacy, research, and community-driven solutions, we strive to uplift underserved populations, promote economic opportunity, and champion equitable policies.
What We're Tackling Right Now
Our most urgent current campaign is the Mattapan Environmental Justice Initiative, a direct response to the ongoing water and soil contamination crisis facing one of Boston’s most historically underserved communities.
Mattapan, a majority-Black neighborhood in Boston, sits along the Neponset River, a waterway burdened by Superfund-related soil contamination and industrial pollution. Residents face degraded drinking-water quality, elevated cancer rates, and higher-than-average birth defects directly linked to decades of environmental neglect.
Federal Designation
Mattapan is a federally designated Environmental Justice (EJ) population under Massachusetts AG/EEA guidelines, EPA Region 1, and the federal Justice40 / CEJST initiative.
GCH, co-anchoring this initiative alongside Mattapan CDC, is leading on-the-ground action: deploying water filtration pilots to high-risk households, pursuing environmental remediation funding, and building a long-term workforce development pipeline so Mattapan residents become the environmental remediation workers of tomorrow.
Superfund-adjacent soil contamination and Neponset River pollution are producing elevated cancer rates and birth defects in a majority-Black, under-resourced Boston neighborhood.
In partnership with specialty partners FieldsPro and Homeworks365, we are deploying household water filtration systems to high-risk families while long-term remediation efforts advance.
We are building an apprenticeship pipeline so Mattapan residents gain priority access to environmental remediation jobs — transforming victims of contamination into the community that heals it.
Co-anchored with Mattapan CDC, and supported by FieldsPro, Renaissance Group Consultants, and Deed/Tetra — a coalition built for lasting environmental impact.
Our Integrated Approach
We don't offer programs in isolation. GCH takes a whole-person, whole-community approach — recognizing that every challenge is connected.
Listen First
Every program begins with listening — to residents, families, community leaders, and the people most affected by the systems we seek to change. We build with communities, not for them.
Address Root Causes
We target the interconnected root causes of inequality — not just their symptoms. Housing instability, mental health, environmental safety, and economic opportunity are treated as integrated challenges.
Build for the Long Term
Every initiative is designed with sustainability in mind — from workforce pipelines that create permanent employment to scholarship programs that develop future community leaders.
Our Core Values
The principles that guide every decision, every program, and every partnership we pursue.
Healing Over Stigma
We lead with compassion, reducing barriers to mental health and recovery by meeting people where they are — not where we think they should be.
Justice & Equity
We center the voices and needs of communities most harmed by systemic inequity — from Mattapan, Boston to Antigua and Barbuda.
Evidence & Integrity
Every program we run is grounded in evidence-based practice, transparent governance, and accountable outcomes we proudly stand behind.
Cultural Sensitivity
Our founder's Caribbean heritage means diversity isn't a checkbox — it's woven into how we design programs, hire staff, and engage communities.
Community Power
We build with communities, not for them. Residents are partners, leaders, and decision-makers throughout every stage of our work.
Global Vision, Local Action
What we do in Mattapan today lays the groundwork for models that can heal communities in Antigua, Barbuda, and beyond.
