About me

David Gonzalez is the founding partner of Sumpter &
Gonzalez, a criminal defense firm whose commitment to social justice involves
defending against serious criminal accusations for both private and indigent
clients. The Firm’s mission to
change people’s lives, in each individual case and in greater society.
Especially in federal and juvenile criminal defense practice, the Firm assists clients beyond the legal issues of
their cases using a team of lawyers and social workers to address the
underlying causes of a client’s involvement in the criminal justice system.

In 2008, he was awarded the Outstanding Young Lawyer of the
Year award by the Austin Young Lawyers Association, and was a finalist in the
American Bar Association’s National Outstanding Young Lawyer of the Year &
in the local Austin Under 40 awards.


David froze to death at Dartmouth
College, then went out West to Stanford Law School
in search of warmer weather. David met his wife on the first day of law school,
but she pretty much ignored him for the next two years until he was able to
convince her to date him midway through their second year.


The two of them juggle their law practice with three kids (all
under the age of 5) in tow.  In his free
time, David enjoys playing dress up, puzzles, Legos, “school,” kitchen, and
typing on the ‘compuper.’
