Hartzog Conger Cason

What Hartzog Conger Cason does

Hartzog Conger Cason LLP is a full-service law firm headquartered in Oklahoma City, Oklahoma, operating from a single office at 201 Robert S. Kerr Avenue. Founded in 1979, the firm employs 38+ attorneys organized across 13 practice areas spanning corporate law, commercial litigation, real estate, tax, estate planning, family law, labor and employment, lending and finance, oil and gas, and nonprofit/charitable organizations. The firm is organized as a Limited Liability Partnership and operates on a traditional professional services revenue model based on hourly billing, fixed fees, contingency, and retainer arrangements for ongoing client engagements.

The firm serves three primary client segments: publicly and privately held companies (across corporate, transactional, and litigation matters), high-net-worth individuals and families (for estate planning, trust administration, wealth transfer, and family law), and nonprofit organizations (for formation, tax-exempt applications, and governance). Customer relationships are acquired through a sales-led go-to-market motion anchored on peer recognition, attorney reputation, and direct referrals rather than traditional advertising.

Hartzog Conger Cason is structured as a founder- and partner-owned LLP with no external private equity or holding company ownership. The firm invests in talent acquisition through a formal summer associate program and lateral hiring, with a steady cadence of partner promotions between 2019 and 2025. There is no proprietary technology platform, no public-facing API, and no disclosed AI or automation capabilities; the firm's value proposition is delivered entirely through attorney expertise and credentials, including Band 1 Chambers USA rankings in Litigation and Tax for 2026 and Tier 1 Best Law Firms recognition across 20 Oklahoma City practice areas.
