About Arturo A Hernandez
After completing his legal education, Arturo A Hernandez III entered private practice and built a career that spans both state and federal courtrooms. He trained for the work of advocacy and the details of court procedure, then began handling matters that required appearances in district court and state tribunals. His path has been steady rather than theatrical. He prefers steady work in the courtroom and at the table.
Early in his career he began appearing in courts across Missouri and Kansas. He is admitted in Missouri and to the federal bar in the Western and Eastern Districts of Missouri, and he is also admitted to practice in the Federal District of Kansas. Those admissions have allowed him to take on cases that move between state and federal systems. The record of his practice shows repeated filings and hearings in those jurisdictions over the years.
Hernandez’s day-to-day work involves courtroom appearances, motion practice and case management. He handles the procedural steps that move a case from filing to resolution. That includes drafting pleadings, arguing hearings and coordinating discovery. He often works on matters that require familiarity with federal civil procedure. He has experience guiding cases through the stages that demand close attention to timing and formal rules.
Colleagues describe Hernandez as methodical in his preparation. He is known for detailed case files and for steady advocacy at hearings. That approach is practical. It serves clients who need clear answers about process and likely outcomes. He tends to keep matters on course and to press for timely resolution when the circumstances allow.
As of 2026, Hernandez practices at McMahon Berger P.C. There he continues to represent clients in the state and federal courts where he is licensed. He handles litigation and related court work in the Western and Eastern Districts of Missouri, in the Federal District of Kansas and in Missouri state courts, concentrating his practice on matters in those jurisdictions.
