About Hannah

Learn Hannah’s areas of practice.

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.

Hannah is AMAZING, she was very professional, and actually cared about our case as oppose to other attorneys that just look at you as a dollar sign! She was very patient, and answered all of our questions promptly, and understood the stress and how neurotic I am. If you want an attorney that will take care of your case as if we’re her own, make sure that you hire her! Thank you Hannah!!!

Hannah - The Rock Star Estate Lawyer
We couldn't ask for more in terms of service, advice, cost, and flexibility. We had a trust and other documents that were 14 years old. Of course, things had changed dramatically for our family, including grandchildren. And, we honestly didn't understand our dated documents. We found Hannah through Yelp. She was highly rated. And, her military service, education, and community service sealed the deal in terms of contacting her. We scheduled our free consultation and brought with us all of our documents. We spent well over an hour with Hannah where we discussed our concerns, asked a lot of questions, and received answers that we could actually understand. At the conclusion of the session, we felt very comfortable that Hannah was the right lawyer to help us update our documents. We learned about how the laws had changed and Hannah reviewed all of our documents and also advised us on which assets should be included in the trust. She provided us with several alternatives for achieving our goals. She then committed to a timeframe when the updated documents would be ready for review. We had several email exchanges during the course of her updating the documents. And, once she delivered draft documents to us, we changed our minds in several areas and we provided Hannah with our requested changes. We fully expected her to request additional monies and made that offer, but she declined to increase the bill. Once the final documents were completed, we met in her office with her notary and signed all of the documents. And, she was patient in answering a few more last minute questions/clarifications. Without hesitation, I would wholeheartedly recommend her to anyone needing legal services. She is personable, smart, patient, flexible, and reasonable. Why would you want to go to anyone else when Hannah can meet and exceed your expectations?

Recommended for Updated Trust / Wills
We consulted with Hannah Sargent to update our very old Trust documents. She patiently listened to us, and answered our many questions, both in person and via email. We never felt rushed or "talked down" to. Documents were conveniently sent in email for our review.

Recommendation of Hannah Sargent
I had the pleasure of working in the same office as Hannah Sargent for just over a year and am writing this review to assure those in need of an attorney that Hannah delivers only the highest quality work. It was common for clients to enter her office feeling concern or worry and leave knowing their case was going to be handled competently by someone with integrity who understood their situation. Hannah is rare in that while being an expert in the legal field she also understands the human side. I would recommend Hannah to any friend or family member without reservation.

She successfully fought against Capital One Credit Card Debt Collection lawsuit against me
I met Ms Hannah in 2008 at Berkley Law Center where she was volunteering her time . Brachfeld & Associates, a collection law firm filed Lawsuit against me in Dec 2008. They were representing TSYS/Natonal Attorney Network. TSYS (Total System solutions) is the debt collection servicing company for Capital One, who assigns attorney through their National Attorney Network to file Lawsuit against debtor. Ms Hannah helped me to write my response to the lawsuit free of cost since she was volunteering . Her response was so effective that Brachfeld and Associate didn't even dare to go to court and case was dismissed. Later she helped me to write all 3 Credit Bureas informing them of the lawsuit and removal on Capital one account from my Credit report . Later I posted a video on You Tube about my success with monster Capital One so that others can benefit. As of today this video has 12609 views and received so many questions from viewers how I did that. I have also created a Facebook page and Blog regarding this Lawsuit so that others in my situation don't get panic when they get summons from court. I wish him all success in her profession.
