California Nonprofits

California-based nonprofits focus on a variety of topics, including healthcare, international affairs, and arts education. Below you’ll find three of the state’s most well-regarded nonprofit organizations.

Fistula Foundation

Fistula — an unfortunate complication that sometimes occurs during childbirth — can leave women incontinent and living in embarrassment for as long as the fistula remains. While highly treatable, women without access to medical care or surgeons may suffer from this complication for the rest of their lives. Opened in San Jose in 2009, the Fistula Foundation raises funds to bring women from African and Asian countries to surgeons who can correct the fistula and allow them to lead happier, healthier lives. This foundation has already helped more than 75,000 women in 33 countries.


Affiliated with the Cancer Treatment Centers of America, the WeSPARK Cancer Support Center works diligently to help cancer patients, survivors, and their loved ones. Operating out of Sherman Oaks, Calif., WeSPARK provides entertainment, emotional support, and all manner of aid to those afflicted by cancer — whether that involves bringing superheroes to visit children during their stays in hospitals or helping to pay for treatments. If you or someone you know is having a difficult time stemming from a cancer diagnosis, WeSPARK may be able to help.

National Novel Writing Month

What started as a self-given challenge, National Novel Writing Month (NaNoWriMo) is now a nonprofit dedicated to helping writers of any age achieve their dream of releasing a novel. NaNoWriMo’s Young Writers Program offers resources, encouragement, and honest criticism to authors under age 18 and K-12 teachers.
