The Team


Michelle “Mika” Domingo is the award-winning Managing Attorney of M.S. Domingo Law Group. With a passion for helping others, Mika Domingo represents people throughout California in matters involving Probate and Trust LitigationProbate Administration, Trust Administration, and Estate Planning.

Mika was selected as a Super Lawyer Rising Star, an honor bestowed upon the top 2.5% of attorneys. She was named a Super Lawyer Rising Star in years 2018-2023. She also holds an Avvo “Superb” rating (a perfect 10 out of 10).

Taking responsibility for over 100 cases at a given time, Mika developed her abilities as a litigator by serving as a Deputy Attorney General for the State of California’s Attorney General’s Office, Department of Justice. She managed cases from inception to resolution in matters involving constitutional law and torts, with an emphasis on the First, Eighth and Fourteenth Amendments, at the State, Appellate and Federal levels. In addition to her rigorous government experience and training, she received additional training in private practice in matters involving trust and estates planning, administration and litigation, probate and civil litigation. Mika’s experience in both the public and private sectors provided a strong foundation for her to advocate fiercely for her clients and achieve the best results.

Mika fulfills her commitment to fairness, legitimacy and equality within the legal community by serving on numerous boards including as President-Elect of California Women Lawyers (CWL), a statewide organization chartered in 1974, dedicated to advancing women in the profession of law, and eliminating all forms of inequities. She has served on the CWL board for seven years, chairing the Judicial Evaluations Committee and this year’s Annual Dinner Committee. Mika served as Past President of Contra Costa County Bar Association Women’s Section, and as a Board Director and Executive Committee member of the Contra Costa County Bar Association, chairing its Diversity, Equity and Inclusion Committee for three years. Mika believes that the justice system should work to benefit everyone, not just the few. Mika fulfills these same commitments to her clients by implementing a client-centered approach – meaning, she places herself in the shoes of those whom she represents. Because the stress and anxiety of pending litigation can cause barriers to communication, empathizing with her clients can overcome that barrier and contribute to a greater success in the litigation process: treating the client as a person, not just another “case.”


In addition to being named a Super Lawyer and having a perfect 10 rating from Avvo, Mika has received numerous awards throughout her career, including:

  • Minority Bar Coalition Unity Award, California Women Lawyers
  • California Young Woman of the Year
  • San Francisco Young Woman of the Year
