Johnny Lanzillo is a highly accomplished criminal defense trial attorney with more than a decade of experience litigating some of the most complex and high-stakes criminal cases in Texas. Renowned for his relentless courtroom advocacy, strategic precision, and unwavering commitment to justice, Johnny has successfully tried cases ranging from Class B misdemeanors to first-degree felonies—including Crimes Against Children, complex federal matters, DWI and intoxication offenses, aggravated assaults, and murder. His deep command of both state and federal criminal procedure has established him as one of North Texas’s most respected and results-driven trial lawyers.
Johnny’s courtroom trajectory took shape the moment he entered the legal profession. After earning his Juris Doctor from Texas Wesleyan School of Law (now Texas A&M School of Law) in 2012, he joined a Dallas County criminal defense firm—trying a first-degree felony to verdict within just two months of being licensed. That remarkable early achievement set the tone for a career defined by bold advocacy, meticulous preparation, and exceptional results.
In 2014, Johnny co-founded a criminal defense firm in Collin County, where he served as managing partner and tried cases throughout North Texas. He later launched his own practice before being recruited to lead the Allen office of a respected criminal defense firm as Criminal Division Trial Chief. Across every leadership role, Johnny earned a reputation for excellence in trial strategy, case management, and client-centered representation.
Johnny’s discipline and competitive drive were forged long before his legal career. A lifelong athlete, he played NCAA Division II baseball at Christian Brothers University before transferring to the University of North Texas, where he served as President of the UNT club baseball team. Today, he continues to compete in men’s slow-pitch softball tournaments nationwide—bringing the same grit, focus, and tenacity that define his work in the courtroom.

Great Lawyer!!
I hired Johnny to represent me on several Dallas County felonies. Given my criminal history and the nature of my cases, he was able to get me a reasonable deal with minimal expense and probation conditions!! I would highly recommend him for anyone in a similar situation!
"Johnny Lanzillo is a competitor in all senses of the word, and this characteristic defines his advocacy. When representing his clients, I have found him to be relentless - whether that is through traveling half the state away to take care of something that another attorney would've farmed out, or in putting in the time to prepare for trial. Strongly recommend him to anyone facing legal troubles."
"Johnny is professional, experienced, and a pleasure to work with. He is dedicated to his clients and will do whatever it takes to provide them with diligent representation."
"Johnny works tirelessly for his clients. He looks forward to each opportunity to improve his all of his client's situations."
"An extremely talented and well respected attorney in the legal community, I wholeheartedly recommend him to anyone looking for a lawyer who knows the law and truly cares about protecting the rights of his clients and getting them the most favorable result possible."
"I endorse this lawyer with no reservation. An extremely talented and well respected attorney in the legal community. Very hardworking and diligent. Consistently achieves superior results. Advice is always practical and on point. I recommend to anyone looking for an attorney who knows the law and truly cares about protecting the rights of clients and achieving the most favorable result possible. I endorse this lawyer."
"John was a third year law student at my prior firm. John helped me tremendously on a major trial. Without his help, I do not believe that we would have obtained a victory. He has a gift of being able to analyze situations quickly and with the client's best interest always at the top of his priority list. I do not hesitate in the least endorsing him, as he strives to be a master of his craft as an attorney."
"I have had many opportunities to witness Mr. Lanzillo's hard work and dedication in zealously defending his clients, and I can personally attest to the fact that he will put his client's interests before anything else. When times are tough, you can count on Mr. Lanzillo to be in your corner."
"Johnny and I work together currently handling a rather large criminal case-load. I can honestly say I could not do my job without him. His vast knowledge of the criminal process coupled with a great level of dedication to our clients makes him an invaluable asset to the firm. Whether it's working late, traveling far distances, or going to court with a briefcase full of cases, Johnny will always go the extra mile to zealously represent his clients. I highly recommend him."
