Adair Myers Stevenson Yagi PLLC

What Adair Myers Stevenson Yagi PLLC does

Adair Myers Stevenson Yagi PLLC is a Houston, Texas-based business law firm established in 1981, operating as a privately held Professional Limited Liability Company with 11 employees and a single office at 24 Greenway Plaza. The firm delivers a full-service practice covering business transactions, commercial litigation, real estate, oil and gas, outside general counsel services, intellectual property (patents, trademarks, copyrights, trade secrets), estate planning and probate, and family law. The client base consists of Houston-area small and mid-sized businesses, individuals and families, and a specialized Japanese-speaking segment served through partner Kenichi Yagi, who is described as one of the few native Japanese-speaking attorneys in Texas with both transactional and litigation experience.

The firm's service model is relationship-based and time-billed, with initial consultations offered at no charge and a published fee schedule covering discrete matters such as company formation ($2,000-$3,000), employment documents, contract drafting, will preparation ($1,500-$2,000), and contingency-based personal injury. Several clients are documented as multi-decade engagements, including 14- to 27-year relationships acting as outside general counsel, suggesting deep institutional retention. Distribution is direct, supported by a content-marketing website, SEO, LinkedIn presence, and dedicated Japanese-language landing pages.

The firm has no technology platform, software product, or AI capability; revenue is professional-services-fee-based and undisclosed. Its growth orientation is reflected in the 2020 elevation of Kenichi Yagi to partner and corresponding rebrand, the 2023 hire of patent attorney Matthew Compton to lead the IP practice, and cross-border affiliations through LawPact (an international independent-firm network) and a partnership with Osaka-based Asai Law Firm, with attorney Takahiro Shinano coordinating US-Japan matters. The firm positions itself as a cost-effective alternative to large law firms offering direct partner involvement and bilingual capability.
