Hallie Zimmerman
Hallie is entering her tenth year of active legal practice. Hallie’s current practice focuses on family law matters, where she is dedicated to navigating her clients through the legal challenges of separation to a fresh start. Hallie’s extensive litigation, negotiation and settlement experience lends itself well to all types of family law matters. Recognizing that no two matters are alike, Hallie provides her clients with well-tailored representation, which perfectly suits their particular circumstances. Hallie has previously worked on disputes arising from residential and commercial real property transactions and complex construction defect matters. She has also managed two California litigation operations for multi-state law firms, handling litigation and judgment enforcement of large financial portfolios. Representing clients throughout California (from Imperial to Siskiyou counties), has given Hallie a unique appreciation for court nuances. She has also effectively handled multiple proceedings before JAMS and the American Arbitration Association. Since 2009, Hallie has provided pro bono family law legal services for Bay Area Legal Aid. Hallie has also been active in the pro bono Lawyer in the Library program administered through the Contra Costa County Bar Association.
