About John-Patrick
John-Patrick Mullen-Lujan earned his Juris Doctor from Chapman University Fowler School of Law in 2020. While at Chapman he completed a Criminal Law Emphasis Certificate, an academic credential that underpins his work in courtroom practice. The law school years provided classroom rigor and opportunities to study trial techniques and evidence, shaping the early contours of his legal approach.
After law school, Mullen-Lujan began his career in litigation. In 2020 he joined Wallin & Klarich, A Law Corporation, as an associate lawyer. There he handled criminal matters and related proceedings, learning the rhythms of trial preparation and client counseling at a firm known for high-volume case work. The associate role gave him hands-on experience in arraignments, discovery disputes and plea negotiations.
In 2022 Mullen-Lujan took on a leadership role at JPLaw, P.C., serving as president. He assumed managerial duties while continuing to handle criminal defense cases. The title reflects a shift from employee to firm leader. It also marked a period where he balanced casework with overseeing day-to-day operations and client intake.
Mullen-Lujan practices in California, where his credentials and early work have centered on criminal defense, including DUI matters. His Chapman certificate aligns with memberships he maintains in several professional organizations: the Orange County Bar Association, the California DUI Lawyers Association and the National Association of Criminal Defense Lawyers. Those affiliations keep him engaged with continuing legal education and peer discussion on evolving defense strategies.
Colleagues describe him as methodical and attentive to procedural detail. In client meetings he tends to prioritize clear explanation of options and next steps. In court he relies on prepared motion practice and an emphasis on factual clarity. The record shows steady involvement in local criminal dockets rather than a public-facing trial celebrity profile.
Outside of courtrooms and firm administration, Mullen-Lujan has focused on building a practice that manages both routine criminal matters and cases that require more intensive litigation. He remains active in professional groups that concentrate on DUI and criminal defense practice. He is currently practicing at JPLaw, P.C., handling criminal defense and DUI cases in California.
