The Magic of
Children's Stories

In my work as a Family Physician, I’ve cared for thousands of patients, including hundreds of children, from newborns to adolescents.

Although I’ve been writing for years, it wasn’t until I became an aunt and later a great-aunt that I started writing children’s stories.

I hope that my unique perspective as a Family Physician, an aunt, and a great-aunt, has given me the insight to write children’s stories that are fun and captivating, but also educational, and woven with life lessons.
