About Benjamin Aaron
Benjamin Aaron Janssen took a direct path into the law. He entered Washburn University School of Law in 2010 and earned his J.D. in 2013. The years in law school shaped his approach to litigation and client work. They also set the stage for a practice grounded in courtroom procedure and statutory detail.
After law school he began practicing in Missouri. He is admitted to practice in the State of Missouri and before the Federal Circuit. Early cases gave him steady experience in contested matters. Over time he added a court-appointed role that broadened his courtroom responsibilities.
Janssen is certified as a Missouri Guardian Ad Litem by the Supreme Court of Missouri. That certification authorizes him to represent the interests of children and vulnerable parties in family and juvenile proceedings. The work requires clear written reports, careful fact-gathering and frequent court appearances. It also demands the ability to explain recommendations to judges who must balance legal standards with real-world family dynamics.
He maintains memberships in professional associations and participates in the routine obligations that come with bar membership. Those connections keep him current on case law developments and local practice rules. They also provide a structure for exchange with other lawyers in the region.
Much of Janssen’s work involves state-court practice in Missouri. He handles discovery, motion practice and hearings that arise in family and juvenile matters tied to his guardian ad litem role. He also accepts matters that present federal questions and has appeared in proceedings before the Federal Circuit. His courtroom time is a mix of contested hearings, settlement conferences and administrative proceedings.
Colleagues describe Janssen as methodical in preparation and precise in courtroom presentations. He tends to favor clear, concise filings over dense legal theory. That stylistic choice aims to make issues accessible to judges and clients alike.
He practices from The Janssen Law Office. There he manages a caseload that combines guardian ad litem appointments with civil matters in Missouri courts and federal filings when they arise. His current practice centers on state and federal matters in Missouri and cases before the Federal Circuit.
