Tierney has been in education for over thirty years. After  finishing her teaching career at a junior college, she decided to pursue her writing career. Creating a workshop for beginning writers, speaking at schools and serving as an officer in the writing group Sleuths’ Ink, are some of the work she does when not writing. Thanks to a fifth grade teacher and forced to write a puppet play, Tierney fell in love with the written word.

Along with serving as a Solar System Ambassador for NASA’s Jet Propulsion Lab and attending Space Camp for Educators, Tierney has traveled across the world. From the Great Wall of China to floating the Okavango Delta of Botswana, Africa, she ties her unique experiences into other writing projects such as the action thrillers in the Enigma Series. Living on a Native American reservation and in a mining town for many years, fuels the kind of characters she never tires of creating.

Besides teaching and writing, Tierney enjoys family, gardening, reading and music. Other pursuits involve researching Biblical archeology and other holy sites that will be included in an upcoming series. Other kinds of research has involved learning new skills with weapons such as a samurai sword.

She has finally settled in Oklahoma, but there’s never a dull moment in Tierney’s life. And that is just the way she likes it.
