Meet our family of “Planeteers”!

Brett Walter

Founder and CEO

Brett, a former homeschool dad of two and veteran Silicon Valley software designer, is the mastermind behind Homeschool Planet. He noticed a gap in the market when it came to homeschool planning solutions and was determined to create one that was of the highest quality. Unlike other software projects, Brett was committed to putting quality first and it's clear that his dedication has paid off based on the hundreds of testimonials and rave reviews that Homeschool Planet has received. Brett has a rich background in software design, having helped create several award-winning products in his career, including Symantec Corporation's flagship product when he served as VP of R&D in its early years. When he's not focused on Homeschool Planet, Brett spends time with his family and dedicates himself to charitable activities.

Robyn Calvi

Chief Operating Officer

Robyn is an integral part of the Homeschool Planet family, with a wealth of experience and expertise in homeschooling and organization. As a homeschooling mother of six for over 27 years, Robyn has a deep understanding of the challenges and joys of homeschooling. Her love of organization and administration led her to become an avid Homeschool Planet user, eventually leading her to become the leader of our team of lesson plan authors. As Chief Operating Officer since 2018, she plays a key role in keeping our planet spinning smoothly, using her passion for helping others to ensure that Homeschool Planet remains the best planner on the planet. With her warm welcome and wealth of knowledge, Robyn is the perfect guide to help you and your family thrive in your homeschooling journey.

Joe DeStefano

Chief Engineer

Joe pretty much single-handedly wrote the tens of thousands of lines of software code that make Homeschool Planet perform its unique magic. With a Ph.D in computer science, Joe has developed several successful software programs, but Brett considers Homeschool Planet to be Joe's true masterpiece. He recorded many of our online video tutorials, manages our toughest support cases, and stars in some of our webinars. Despite his geek credentials, Joe is a fun-loving guy with whom you'd enjoy sharing a meal. He lives in the Boston area with his wife, who teaches math at a local university. Their two daughters are grown and pursuing academic careers. When he's not working on Homeschool Planet, Joe loves playing soccer and attending live music events. He and Robyn are both die-hard RedSox fans. Go Sox!

Cooper Walter


Cooper, our newest engineer, brings a unique perspective to the team. As a former homeschooled student himself, he understands firsthand the benefits of homeschooling and is passionate about contributing to a product that supports families on their educational journeys. After earning his bachelor's degree in Human Biology, Health, and Society from Cornell University, Cooper discovered a love for software engineering and is excited to apply his skills to further enhance Homeschool Planet. In his free time, Cooper enjoys singing in the shower to oldies music and playing the guitar. He looks forward to getting to know his colleagues and helping to ensure the continued success of Homeschool Planet.

Criston White

Customer Service Lead

Criston is part of our customer service and lesson planning teams, residing in rural Saskatchewan, Canada, with her husband and four children. Having homeschooled since 2017, she fell in love with the concept, but dreaded the erasing, rewriting, and mental reworking that every life change necessitated. In search of a digital option to prevent paper planning stress, she researched various tools and found Homeschool Planet, which became her go-to solution. Since then, she has been an avid user of the platform, utilizing it to adapt to her changing homeschooling style, planning methods, children's needs, and life situations. In 2021, she joined the Homeschool Planet team, bringing her expertise in customer service, technical support, and creative problem-solving skills to assist other users with their unique planning situations. Her knowledge of the platform sometimes often leaves our engineering team impressed.
