Ryan is also one half of the husband/wife musical behind Tiny Prime, a world of music, books, and educational tools created to support children’s mental health and strengthen family connections. He and his wife, Lisa, began this effort as new parents looking to nurture their own children’s early emotional development. Like so many parents before them, Ryan and Lisa found that the timeless tradition of sharing songs and stories was key to cementing lessons of love, joy, confidence, gratitude, resilience, and more.
