Connecticut Nonprofits

Many Connecticut nonprofits focus on disaster relief/prevention, financial aid for veterans, and matters of civil rights. Here are three of the state’s most highly regarded nonprofits.

Sandy Hook Promise

The tragic shooting at Sandy Hook Elementary School continues to serve as a horrifying reminder of the dangers of gun violence. Sandy Hook Promise — a nonprofit seeking to help prevent future gun-related tragedies — educates children and teachers on what to do if an active shooter enters their school. It also shares ways to help prevent situations like this and serves as an advocate of those affected by a school shooting, providing both emotional and financial support to impacted families and communities.

Work Vessels for Veterans

Founded in 2008, this nonprofit supplies military veterans with tools and materials they need to start their own businesses. What started as a group giving boats to veterans so they could fish commercially in Mystic, Conn., grew into a large network of like-minded people setting veterans up with heavy equipment, power tools, vehicles, and just about anything else they might need to launch their own small business. To honor veterans’ service to the United States, this nonprofit now helps these individuals focus on the work they always dreamed of doing.

Katal Center for Equity, Health, and Justice

Operating in New York state and Connecticut, this nonprofit organization seeks to make the United States a more open and equal place to live for people of all heritages and orientations. Founded in 2016, the Katal Center initially focused on bringing attention to wrongful incarcerations and mass criminalization — especially regarding arrests made for drugs that are now decriminalized. Today, it continues to call attention to these matters and advocates for more evidence-based solutions in modern policing and the justice system vs. rulings made on tradition and older decisions.
