Kelly started her career in publishing as a Life Sciences editor at an academic publisher where she learned she loved working with authors, but that post-graduate textbooks and monographs were never going to hold a candle to working on kids' books. Since making that career leap, she's never looked back. 

For the past 15 years, she's been championing writers and artists in nearly every category, format, and age group. She represents debut authors and illustrators as well as bestsellers and award-winning clients.

Kelly is on the Advisory Board for UCSD's Certificate in Writing and Illustrating for Children; is the co-founder of the City Heights Young Writers Workshop; and serves on the AALA's Diversity, Equity and Inclusion Committee, where she's helping to launch a mentorship program providing support to agents from marginalized backgrounds.

I'm the product of a kindergarten teacher mom and a salesman dad. Pretty much the perfect combination for a kids literary agent!
