Get to Know Anna

What is your favorite part of your job?

I love that antitrust law is continually changing. The Sherman Act is a statute of few words, but an enormous body of jurisprudence has developed around it through the common law. As societal values change and new technologies develop, antitrust law adapts with it. I think there is an increasing understanding that antitrust law plays an important role in the health of our economy and our democracy. Antitrust is intellectually interesting, but it is also very meaningful.

What, outside of your work, are you most passionate about?

Volunteering in my community. I am president of the Association of Latino Marin Attorneys and a volunteer judge for Marin County Youth Court, a diversion program for youth based on restorative-justice principles.

How has your background shaped the kind of lawyer you are?

As the child of immigrants and the first in my family to attend college, I have felt an enormous duty to serve this country, which has truly been a land of opportunity for my parents and grandparents. My mom, the Puerto Rican-born daughter of a garment worker, and my dad, the son of a US Marine and letter carrier, instilled in me not just the value of education but open-mindedness.

What is something that people would be surprised to learn about you?

My husband and I are avid tandem cyclists. A few years back, we became the first tandem couple to complete “La Vuelta,” a 375-mile, three-day ride circumnavigating the island of Puerto Rico. Also, I’m a pretty decent baker: My peach pie once earned honorable mention at the Marin County Fair!
