Holstrom, Block & Parke

What Holstrom, Block & Parke does

Holstrom, Block & Parke, APLC is a California professional law corporation headquartered in Corona, California, operating as a mid-sized regional family law firm with eight physical offices across Southern California and one in San Francisco. The firm employs 23 attorneys and over 50 support staff, delivering services across four core practice areas: Family Law (divorce, custody, child and spousal support, domestic violence, parental alienation, stepparent adoption), Appellate Law (family law and civil appeals), Collaborative Divorce and Mediation, and the Sandoval Legacy Group division covering Elder Law, Tax Law, and Estate Planning and Probate. The practice is built on a talent-dense model featuring multiple Certified Family Law Specialists (CFLS), Certified Appellate Law Specialists, and Certified Estate Planning and Elder Law Attorneys, with the managing partnership held by Dayn A. Holstrom (CFLS) and the Orange County office led by Carrie Block (CFLS).

The firm operates a traditional professional services revenue model, billing via hourly rates and flat fees depending on matter type, with no publicly disclosed fee schedules or subscription products. Customer acquisition is dual-track: a sales-led motion through free phone consultations and website-driven inbound inquiries, alongside a community-led motion anchored by local bar association participation, a legal talk radio show on Go Country 105FM hosted by Kristen Holstrom, the Divorce Authority podcast, educational webinars, and an active blog targeting Southern California families. Primary customer segments are individuals and families navigating divorce and custody disputes, high-net-worth individuals and professionals (business owners, doctors) requiring complex asset division, and estate planning clients seeking wills, trusts, and elder law services.

Brand equity has been built through sustained consecutive recognition including Super Lawyers selections (2017-2025), Best Lawyers rankings (2014-2026), Martindale AV Preeminent rating, American Academy of Matrimonial Lawyers membership, and Doyle's Guide listings. The firm maintains a multi-channel presence across Facebook, X, Instagram, YouTube, and LinkedIn. No external funding, acquisitions, technology platform, patents, or AI capabilities are disclosed in the available data, and revenue figures are not publicly reported.
