What Holstrom, Sissung, Marks & Anderson does

Holstrom, Block & Parke, APLC (operating in the input under the name Holstrom, Sissung, Marks & Anderson) is a Southern California-headquartered family law firm providing legal representation across divorce, child custody, child support, domestic violence, appellate, estate planning, probate, and mediation matters. The firm serves individuals and families — with particular focus on complex, high-conflict, and high-asset cases — through nine office locations spanning Corona, Newport Beach, Los Angeles, San Francisco, San Diego, Vista, Riverside, Sacramento, and Temecula Valley, with location-specific digital presence and a primary referral and direct-attorney-client acquisition model.

The firm's core product is professional legal services delivered by approximately 30 attorneys, the majority of whom hold Certified Family Law Specialist (CFLS) credentials granted by the State Bar of California, with select attorneys additionally holding CEPLS, CTLS, CALS, or CELA credentials in estate planning. The underlying technology stack consists of standard law firm practice management tools; no proprietary AI, automation, or technology platform is disclosed. The firm markets through a multi-channel digital ecosystem combining SEO-optimized location landing pages, a blog, webinars, a video library, and active social profiles on Facebook, X, Instagram, YouTube, and LinkedIn.

The business model is professional services billing on an hourly, flat fee, or matter-based arrangement, with fees determined by case complexity, attorney experience, and matter type. A free consultation is offered for divorce matters as a funnel entry point. Revenue is generated entirely from individual consumer legal matters with no disclosed enterprise accounts, subscription revenue, or recurring contracts; the firm has no outside funding, no parent company, and is partner-owned as a California professional law corporation.
