    Sarah Wharton

    Founder and Executive Director

    Sarah has always loved cooking, teaching, and helping the planet, and she combined all three when she founded Little Chefs, Big Change. With a masters from Cornell and years of experience managing after-school cooking programs, Sarah knows how to make healthy eating fun and accessible for kids. Sarah started teaching cooking classes in 2015, inspiring students and families to try new foods and make veggies taste delicious. Over the years, Sarah has compiled many kid-approved recipes and has developed the ability to teach kids how to cook pretty much anywhere- a school kitchen, a classroom, a cafeteria, outside…give her an electrical outlet and a group of kids, and dinner will be ready an hour later! At home, her favorite taste-testers are her kids Emory and Simon and her partner Tom.

    Favorite Memory with LCBC:
    “One of my favorite moments has always been seeing the kids’ faces light up when they realize that beans can make really good brownies. You can see the look of confusion as their mind tries to understand how it could be possible. It's beans, but it still tastes good.

    I especially love seeing the Little Chefs building confidence and independence as they work with their peers to create a meal that they all get to enjoy together. Little Chef's Big Change is empowering kids for the future, and I'm honored to be a part of it.”

    Favorite Memory With LCBC:
    “I’ve had the joy of serving on the board since January 2024, and it has been an incredible experience watching this program create confidence, creativity, and community one meal at a time.

    One of my favorite things about LCBC is seeing how proud the kids are of what they cook. It’s not just about enjoying the food themselves—they can’t wait to share it. They eagerly ask to bring plates to their teachers, parents, and friends and they beam with excitement as they show off what they’ve made. That instinct to nourish and care for others is so special, and it speaks to the heart of this program.

    Little Chefs, Big Change is empowering kids far beyond the kitchen, and I’m thrilled to play a small part in helping this incredible work grow.”
