About me

Jennifer moved to Ventura County in 2000 and was employed as a Deputy Probation Officer while she attended law school.  Jennifer focuses the majority of her practice on family law matters.  She also handles guardianships and some criminal defense matters.  


Jennifer is a strong advocate for her clients, whether in settlement negotiations or in the courtroom.  She communicates with her client to determine what is important them, to determine their goals and to advise them if their goals can realistically be attained.  

She takes the time to guide her clients through the legal process so they know what to expect and can make an informed decision.  Additionally, Jennifer makes a point to be available to her clients; whether by phone, e-mail or an in person appointment.

    I have worked cases with Jennifer as opposing counsel and have a lot of respect for her. She is tough, professional and does not create disputes where they don't exist. She is a great advocate for her clients and works hard to achieve the best possible result for them.
