About Chuck
Chuck Chionuma earned his J.D. from the University of Missouri–Kansas City School of Law in 1984. He completed his legal studies at a time of change in the profession. The degree set the stage for a long career practicing across state lines.
He became a partner at Chionuma Law Office in 1985. That early move into partnership shaped his professional life. Over the years he has practiced under the name Chionuma Law Firm, LLC and has maintained a steady presence in private practice.
Chionuma is admitted to practice in both Missouri and Oklahoma. He has spent decades working in the two state systems and navigating their differing procedures. That experience means he is familiar with local rules and court processes in each jurisdiction.
Throughout his career he has remained active in the legal community. He holds current memberships in professional associations and participates in the networks that connect lawyers across the region. Colleagues describe him as a steady presence in the office and the courtroom. He has handled matters that required careful preparation and attention to procedural detail. He also brings institutional knowledge from long service in a small law practice, where a lawyer often handles many aspects of a case personally, from intake to resolution.
The office he practices from is Chionuma Law Firm, LLC. The firm has operated under that name while serving individuals and businesses across state lines. Today he continues to serve clients in both Missouri and Oklahoma, representing them in matters that require an understanding of each state’s legal framework. His current practice serves clients in Missouri and Oklahoma.
