Julie D. Mason – Founder and Director
Julie designed Biddy Sports and has been refining it since 1993. She loves working with young children and their families.  Infused with the joy of sports, learning, and some silliness, she strongly believes that young children should just simply play, experiencing sports activity with no pressure.  Julie’s experience encompasses the fields of recreation, non- profit administration, and community engagement.  She plays almost as good as a preschooler most days. Julie’s exceptional organizational skills and volunteer management are major strengths of the program.

Scott Davis – Staff @ Brentwood Scott and Mikey
Scott Davis has been a Biddy Sports coach since 2004 and stepped up to lead the Brentwood seasons in 2011.  His experience and love of the program shows each week.


Hailee Didio – Staff @ Oakley

Hailee has been with us since 2017 and comes from an education background. She leads the program in Oakley with professionalism and lots of happy smiles.

Dave Persson  was Julie’s partner and a well-loved member of the Biddy Sports team from 2002 until his unexpected death in 2011.  His generous nature and enthusiasm made children and adults enjoy his company.  His passions included his family, rugby, golf, dogs, competitive coaching and refereeing from 1996, including high school basketball throughout the Bay Area. His many achievements include being a volunteer fireman in New Jersey for 12 years before relocating to CA.  He is sorely missed by many.
