About me

Ms. Seeley is a Certified Specialist in Family Law by the State Bar of California, Board of Legal Specialization.

Ms. Seeley’s practice focuses on dissolution cases involving high asset and complex financial issues such as the division of interests in closely-held businesses, real estate, and equity compensation, including stock options and RSU’s.  Ms. Seeley also has extensive experience with high-conflict custody matters and relocation/ move-away cases.

Ms. Seeley brings over 30 years of civil litigation experience to the firm and represents clients through all phases of family law litigation before private judges and in public courthouses.   She is also certified in and practices collaborative law.  For clients who elect mediation to resolve their issues, Ms. Seeley acts both as a mediator and as a consulting attorney in the mediation setting.

Ms. Seeley’s style of advocacy and personal approach to her cases enables her to achieve favorable outcomes for her clients.   When necessary, she engages the expertise of professionals such as forensic accountants, appraisers and psychologists to assist in the resolution of case issues.
