Claimed Lawyer ProfileQ&ASocial Media

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.
