The boring Bio for Phillip would mention his years of experience in Privacy, Security, Governance, and Audit. It would tell of the business sectors he's worked with, and perhaps even the companies and professional organizations he's been affiliated with for the last 25+ years.

This is not that Bio.

Telling stories and pulling connections together from places unexpected; using Poetry, Literature, and Fairy Tales to make points understood by those not in the tech field; and sometimes writing way too strange abstracts—these are the things that make Phillip happy.

When a group wants him to come up with a talk, his wheels start turning and they don't stop until something is on paper (or on a screen ). The results are usually a journey that leave the listeners somewhere they weren't when the story began.

Phillip prefers people thinking of him more as someone who looks at the world differently but helps to get you where you need to be.
