Heidi D. Collier has devoted nearly three decades to the practice of family law in California, representing clients in divorce, custody, support, and post-judgment matters throughout San Diego County. Licensed since 1996, she is the founder of Heidi D. Collier, APLC, a practice focused exclusively on family law.

Collier is a Board-Certified Family Law Specialist through the California Board of Legal Specialization, a designation earned by a limited percentage of attorneys who meet rigorous standards of experience, peer review, continuing education, and examination. The certification reflects a career centered not on general practice, but on the procedural and financial complexities unique to family court litigation.

Her work regularly involves contested custody disputes, spousal and child support determinations, property division, domestic violence restraining orders, and post-judgment modifications. In California family courts, outcomes are often shaped by preparation, financial clarity, and strategic advocacy. Collier’s approach emphasizes detailed case development, disciplined negotiation, and courtroom readiness when resolution cannot be achieved through mediation.

Active within the regional legal community, Collier has served on the Board of Directors of the San Diego Family Law Bar Association and maintains involvement in professional organizations dedicated to family law practice. Her long-standing focus in this area has established her as a steady presence in matters where legal decisions carry lasting personal and financial consequences.

For 2026, MyLegalWin recognizes Heidi D. Collier as one of the Top Attorneys in America for her board-certified specialization, sustained family law practice, and standing within the San Diego legal community.
