Tennille Duffy

  • Criminal Law, Domestic Violence
Claimed Lawyer Profile

Ms. Duffy is an Australian-trained attorney who excelled at law school, achieving entry into a competitive practical law program, placing first in Advanced Criminal Law in her final year, and being awarded her law degree with Honors. She began her career in Sydney by clerking for a Supreme Court Judge. She then moved into a criminal defense practice where she represented clients in matters ranging from shoplifting and DUI to sexual assault and murder and has conducted hundreds of trials. She earned a reputation as an honest and forthright advocate who was always well prepared and was not afraid to stand up to the police or their witnesses in court.

Tennille then took a break from criminal defense to work in New Delhi, India, in international police reform efforts and in legal education. She also spent a semester teaching Criminal Law at the University of New South Wales, one of the top law schools in Australia.

Motivated to return to criminal defense so she could again do the direct work she so enjoys in representing clients, Tennille passed the California Bar Exam and moved to the Bay Area in 2013, and joined Summit Defense in 2014.
