Review Erin Walz

About Me

I concentrate my practice on education law, and represent public school districts throughout Arizona.  My practice is focused on student discipline, employee discipline, IDEA compliance and hearings, IDEA appeals, as well as general advice for school districts. 


I was a commercial litigator for 16 years before I began representing school districts.  I have conducted jury and bench trials in state and federal courts, as well as before administrative judicial bodies.


I have been practicing since 1996. I am admitted to practice before the Arizona, Illinois and Michigan state courts, and numerous federal courts.
