Because of my work, there are many causes I care about deeply. But I was asked to pick just one. It sounds kind of corny and cliché, but our children are our future. That’s why I support programs and nonprofits who help advance education and provide enrichment programs to kids who may have gone under the radar."

Favorite Cause
There are dozens of causes I support, but I'm most passionate about empowering and educating women and girls in developing nations. Time and again, it's been proven that unleashing the vast potential of women is the key to lifting families and communities out of poverty. Luckily, there are some incredible organizations fighting to ensure that these girls have access to the educational resources we often take for granted.

Favorite Cause
Ocean pollution is the biggest crime on this planet. I believe we are all empowered to make a global change by local action. Saving a sea turtle from drowning made me feel like a super hero. After that, I decided to pledge all my vacation time to volunteer for ocean conservancy. Since single-use products from boats and seaside picnics accounts for 60 percent of the trash in the ocean, I also encourage everyone to become a recycling ninja and keep our blue ecosystem intact. Lets save our oceans together. One sea turtle at a time!

As a student of the arts, I am a firm believer in the importance of arts education in our schools. Not only does arts education inspire creativity, passion and individuality, it helps children develop social and emotional skills, academic achievement and is an integral part of their growth process. Whether it be music, dance, theater or the visual arts, each child deserves to be exposed to the arts as a safe forum for self-expression.

Favorite Cause
It breaks my heart to hear about hunger among children, especially here in the US where so much food is wasted. I regularly donate quality food to my local food bank and try to spread the word. Even in the affluent Connecticut town where I live, there are families who depend on that small food bank to feed their kids. Donate money, your time or food to your local food bank – and not that can of anchovies you’ve had in the back of your pantry.

Favorite Cause
My personal favorites are causes dedicated to fighting for basic human rights of those around the world. Working at Charitybuzz, as well as personal volunteer work, has given me a great perspective of how lucky we are to live and work where we do. With that awareness, I hope to impact change to those around the world who weren't as fortunate to be born into better circumstances and all that comes with it; basic access to food, water, shelter, personal safety and freedom."
