I was born and raised in Southern California, in a family that included a multi-generation law firm. Despite being raised around the legal profession, I initially pursued a career in academia, with an emphasis on philosophy.  

After teaching philosophy, ethics, interpersonal communication, and introductory psychology at the associate’s-degree level for several years, I realized that practicing law was my opportunity to serve others beyond the theoretical. I entered law school the following year.

Our firm’s founding partner, Angelo L. Rosa, was my first employer after law school. After eight months of performing legal research and writing for him, he allowed me to sit as second chair in a contentious arbitration involving a multi-billion Dollar publicly held company: it was intense, immersive, highly educational. . .and thrilling.

I now manage the day to day operation of Rosa PLLC’s litigation practice. The practice centers on vigorous and ethical representation of entities and individuals in all aspects of commercial litigation. The emphasis is on absolute quality in work product, client service, and professionalism.
