Attorney Michael S. Callahan is Board Certified in Personal Injury Trial Law by the Texas Board of Legal Specialization — a distinction earned by fewer than 2% of Texas attorneys, according to the firm’s official website. He also brings a background in mechanical engineering, which the firm identifies as a differentiator in complex truck and vehicle accident cases. Attorney Casey M. Brown previously represented insurance companies from the defense side before joining The Callahan Law Firm, providing an insider understanding of how insurers evaluate and manage claims. The firm has recovered tens of millions of dollars for clients, per its official publications. The firm intentionally limits its caseload to ensure dedicated attorney attention on each matter.
In addition to its Houston office, The Callahan Law Firm maintains a Pasadena, TX office for clients in eastern Harris County and surrounding areas.
