Nissan and I became a Nissan Master and ASE Master Automobile
Technician, primarily focusing on electrical and drivability
In the years to follow, I opened a bike shop full-time, became
service manager of Biker’s Dream in Sacramento, and in 1996, went
to work for ALLDATA. My career now had taken a new direction.

knowledge with journalism and become a senior automotive writer,
a marketing writer, PR manager, and product manager.
In 2009, I had the opportunity to teach advanced automotive
diagnostics and emissions at Universal Technical Institute.
During the next four years, I had the pleasure of teaching
students the skills they needed to be successful diagnostic
In 2013, I came back to ALLDATA to apply my expertise to a
fantastic product — ALLDATA Tech-Assist. As the Tech-Assist team
supervisor, I’m excited to lead a team that provides world-class
diagnostic solutions that help technicians effectively fix
