Garth Callaghan

Father, Author, Speaker

Imagine a world where people wake up every day with the knowledge that they matter. With the time Garth has left – he has committed himself to help create this world.

Shortly after his daughter, Emma, turned twelve, Garth learned he had kidney cancer. Determined to make the time he had left meaningful, he made a promise to compile years’ worth of notes to give his daughter through her high school graduation. What he did not know is that promise would become a book – Napkin Notes.

Most people refer to him as the “Napkin Notes Dad.” It is a title he takes pride in as it represents a lifetime of relationship building – not just with his daughter but with everyone he meets.
