Attorney John Mueller was born and raised near Milwaukee, Wisconsin, John graduated from Purdue University (’91) and Saint Louis University School of Law (’94). His early success in appellate law sparked his career as an appellate attorney. While a full-time law student working part-time for the Federal Public Defender Eastern District of Missouri, John drafted an appellate brief that resulted in the reversal, on sufficiency of the evidence grounds, of a client’s conviction and 10-year federal prison sentence.

Following law school, John accepted a position as a Judicial Law Clerk to the Honorable Thomas M. Welch, Illinois 5th District Appellate Court. John spent 12 years as an Appellate Law Clerk, reading hundreds of briefs, engaging in extensive research on a broad range of legal issues, and drafting numerous dispositions. During his tenure as an Appellate Law Clerk, John not only fine-tuned his already exceptional legal research and writing skills, but most importantly, learned what constitutes a winning brief and what arguments give a client the best chances of success on appeal.

If you received an unfavorable verdict and wish to appeal, if you received a favorable verdict and the other party is appealing, or if you are an attorney seeking representation for a client in an appeal, contact John to schedule a consultation. John can help you navigate through the sometimes difficult and complex appellate process.

As an attorney Of Counsel at Westmont Law Offices, S.C., John brings his legal talents to other areas of the law as well, including family law, estate planning, and other civil matters. John has passed three bar exams and is admitted to practice law in Missouri (’94), Illinois (’95), and Wisconsin (’13).

John enjoys spending his free time with his three children and staying active, preferably exploring the world on his bicycle, having already pedaled across much of the United States, Canada, and parts of Europe.
