About me

As a former Maricopa County Public Defender, I know all about the rights of those accused of crimes.  I help clients navigate the court system, with compassion, grace, and the experience of over eleven years practicing law.  I will be your advocate every step of the way.

    I had the pleasure of working with Gretchen at the public defenders office in Phoenix Arizona when we were both new lawyers. I now see she is benefiting clients in the private sector, albeit in another state. Anyone with Gretchen by their side should feel fortunate and very confident.
