Hannah Halverson Sargent

About me

As the principal attorney at Sargent Law Offices, I am dedicated to achieving the best possible outcome for my clients.  Whether involved in business planning, formation, dissolution, mergers & acquisitions or assisting my clients with their personal estate planning needs, I ensure that I approach each step with thoughtfulness and vigor.


In my past life I was a military officer, company commander, and AH-64D Apache Helicopter pilot.  My time in the military taught me patience, strategy, empathy and decisiveness.  These skills translate into my practice.  


Prior to beginning my own practice, I spent time performing clinical work for the indigent population in the East Bay and clerking at the U.S. Attorney’s Office in San Jose.  I was editor-in-chief of the Berkeley Journal of Criminal Law and a recipient of the Prosser Prize. 


Please contact me with your business and estate planning needs.
