About:
A Minnesota native and graduate of the prestigious William Mitchell College of Law in St. Paul, John worked as an Assistant City Attorney for the city of Windom immediately after passing the bar. During his four-year term, he handled a variety of different cases and honed his legal and courtroom skills. In 1996, he visited Arizona and decided to make it his home. He has never looked back. From 1996 to 1998 he was Deputy County Attorney for the Maricopa County, Major Crimes and Vehicular Crimes Bureau. During his tenure with the County Attorney’s Office he saw first-hand the impact that criminal behavior and criminal convictions had on the family. He watched as cases that began in Criminal Court migrated to the Family Law system and witnessed the trauma that manifest itself in families affected by the destructive behavior of a parent, spouse or an adult child. And he saw how many families could have been saved if the family would have had prior help. For that reason and several more that are equally compelling, John Gaertner made a decision in 1998 to open a practice that dealt exclusively with Family Law. He committed himself and his staff to providing families with the most professional, profound and pro-active legal advice and support possible. He dedicated himself to helping families navigate the legal challenges that they often face when reconciling conflicts and resolving challenging domestic issues. He is committed to saving the family first but when that is not an option, seeking resolutions that provide children with the best possible environments and parents with practical and successful co-parenting arrangements. John is an expert and authority in matters of custody, spousal support, parents and grandparents rights and always aims at the best and least dramatic process.

"I can’t express enough gratitude for what John Gaertner did for me during one of the darkest times in my life. My ex falsely accused me of molesting my daughter in an attempt to gain an advantage in a custody battle. It was a devastating and terrifying experience—but John handled it with unwavering professionalism, compassion, and strength. During the trial, John’s courtroom presence was calm, confident, and highly strategic. When he cross-examined my ex, he laid out a clear, detailed timeline of events that directly contradicted the allegations. It was a turning point in the case. His questioning was methodical and respectful, but absolutely devastating to the credibility of the accusations. Watching him work in court gave me hope when I needed it most. Thanks to his preparation, legal skill, and belief in the truth, I was fully cleared of the false claims and able to keep my relationship with my daughter intact. John Gaertner didn’t just defend me—he saved my future. If you’re facing false accusations or a high-conflict custody case, I wholeheartedly recommend John. He’s the attorney you want when everything is on the line."

"I have worked with John Gaertner in several Family Law cases and have known him for over 5 years. He cared about me and my family and represented us in the most professional way. He’s responsive to all forms of communication in a timely manner. John Gaertner is honest and trustworthy and will represent you with compassion. He has a high degree of family and criminal law knowledge. Both cases were contentious and he knew when to be assertive for our best interests. The outcomes were both in my family’s favor. I highly recommend John Gaertner law services."

"I can’t recommend John enough! He handled my case and my boyfriend’s, and because of how great he was, I referred him to a friend and my brother, who both had amazing experiences as well. In court, he’s sharp and confident, while the other lawyer was fumbling with pointless questions, John got straight to the point and made a strong case to the judge. He truly cares about his clients and treats every case as if he were fighting for himself. Thanks to him, we were awarded everything we asked for. If you need a lawyer who will fight for you, John is the one to call!"
