Diego Mulato Castillo was born in El Salvador and immigrated to the United States in 2000, settling in Sonoma County, California with his family.

Diego graduated from the University of California College of the Law, San Francisco in May 2024. Throughout both his graduate and undergraduate studies, Diego worked with various plaintiff’s litigation firms until eventually becoming interested in personal injury when he interned with Dolan Law Firm during the summer of 2023, a role he returned to as an associate attorney in 2025.

Before joining our firm, Diego spent time practicing employment law and government benefits representation, sharpening his skills in legal advocacy. Throughout his work, Diego has expressed a steadfast dedication to ensuring that individuals are adequately compensated for the injustices they face, and his approach to the practice in law is rooted in compassion and commitment to his clients.

When he’s out of the office, Diego can be found reading a good book or enjoying the outdoors on one of the many trails through the San Francisco Bay Area.
