I've created user personas for dozens of clients/organizations in domains such as technology, hardware, security, higher education, and consumer goods.

These include traditional narrative-based personas that are designed to engender empathy with users...

As well as playful reminders that developers printed out and pinned on their walls to affirm that "we are not our users"...

The persona I created for Smith College students and alumnae even inspired a strategic branding campaign for their web site entitled "I Am Smith."
