Editorial Verdict

Why Choose Gilleon Law Firm, APC?

Gilleon Law is a small, trial-focused San Diego firm rather than a TV-advertising injury mill. Founder Dan Gilleon has a reputation for taking on cases other firms decline — particularly sexual-abuse and employment-discrimination matters where defendant institutions fight hard. Anna Yum's practice combines personal injury and employment, an unusual but effective combination when workplace incidents involve both physical harm and discrimination claims. Best fit if your case involves serious injury, sexual abuse, employment harassment, or any matter where the path to recovery likely runs through litigation rather than quick settlement.

What Clients Say

Client
Sandra K.
Sexual Abuse Survivor · Institutional
★★★★★
Dan and his team handled my case with care — and with the relentlessness it actually needed. They went after the institution that allowed the abuse, and we won a meaningful recovery. They believed me when others didn't.
Client
Michael R.
Catastrophic Injury · Pacific Highway
★★★★★
Bicycle vs. truck collision left me with a brain injury. The firm built the case carefully, retained accident-reconstruction experts, and won a settlement that covers my long-term care. Couldn't have done it alone.
Client
Patricia L.
Workplace Harassment · La Jolla
★★★★★
Anna handled my workplace harassment case start to finish. She filed an EEOC charge, took depositions, and we settled for back pay and punitive damages. Real expertise and real empathy.

FAQ

Common Questions About This Firm

Does the firm handle institutional sexual abuse cases?
Yes — including cases against schools, religious institutions, employers, and other organizations whose failures allowed abuse to occur. California's AB 218 extended the statute of limitations for childhood sexual assault claims, and the firm has experience with the discovery and expert work these cases require.
What's the difference between sexual abuse and sexual assault claims?
Sexual abuse claims often involve a pattern over time and an institutional defendant (school, church, employer); sexual assault claims often involve a single incident. Both are civil cases (separate from any criminal prosecution) seeking damages from the perpetrator and any institution that enabled the conduct.
How does California comparative fault work?
California is a pure comparative fault state. You can recover damages even if you were more than 50% at fault — your recovery is reduced by your percentage. This is more plaintiff-friendly than the 51% bar used in many other states.
Does the firm take cases outside San Diego?
Yes. The firm represents clients throughout San Diego County, Orange County, and Los Angeles County. Federal cases proceed in the Southern District of California.
Where is the office?
1320 Columbia Street, San Diego, CA 92101 — downtown, two blocks from the Santa Fe train station. On-site parking available. Phone (619) 702-8623.
