Firm Details

Wampler & Passanise Law Office has been one of the Midwest’s leading criminal defense firms for the past 70 years. A key point-of-difference is its cross-functional team approach and experience litigating in the courtroom. 

Joseph S. Passanise and Associate Attorney Taylon Sumners represent adults and juveniles in Missouri facing serious criminal allegations, specializing in white-collar crime, fraud, homicide, sex-related offenses, domestic violence, and probation violations. In addition to criminal defense, the attorneys, paralegals, and investigators focus on ways to create positive lifelong impact for clients—often working with medical, mental health, and probation and parole professionals to ensure positive outcomes.  

Passanise is a Fellow of the American Board of Criminal Lawyers (ABCL), a member of the National College of DUI Defense, the National Trial Lawyers Criminal Defense Top 100 and was recognized by Best Lawyers in America, 2022 Ed. As Springfield Lawyer of the Year for Criminal Defense: White Collar. He was appointed by the Governor to the Missouri Board of Tourism in 2020. In 2021, Sumners was named an Up-and-Coming Trusted Advisor by the Springfield Business Journal and appointed to the Springfield-Greene County Historic Sites Board. Passanise and Sumners also received AVVO’s Client’s Choice Award.

The Firm overall has been recognized by Super Lawyers® for Criminal Defense in Missouri and Kansas. It was also recognized in U.S. News & World Report and Best Lawyers® Best Law Firms in 2021. The firm will be forever grateful for the leadership and tenacity of Wampler, who died in 2021 at the age of 81.
