Kathryn Lammers heads H&L’s family law department. She is a skilled advocate with years of experience representing clients in all aspects of family law including trials, mediations, ENEs, moderated settlement conferences, and appeals.  Ms. Lammers believes that being a good lawyer requires more than just an understanding of the legal issues. She believes a good lawyer has good instincts and empathy and can analyze the symptoms of larger issues and address both the symptoms and the issues intelligently and effectively.

Katie established the family law practice at Heimerl & Lammers in 2009, building it into one of the premier family law practices in Minnesota. Her department of 5 dedicated family law attorneys helps people throughout the Twin Cities and greater Minnesota in every type of family law matter including divorce, custody, asset division, adoption, and more.

Katie’s clients have described her as “knowledgeable”, “excellent”, and an “attorney who truly cares.”  Her clients have lauded her for being calm and collected in court, and tough on the opposition.  

Katie has represented hundreds of clients in civil litigation cases in Minnesota, the majority of which have been in family law matters.   She has experience in virtually every aspect of the litigation process including appeals, jury trials, bench trials, summary judgment hearings, motion practice, and ADR, including Early Neutral Evaluations.

She is a rule 114 qualified neutral and a qualified family law mediator.  She is certified as a SENE and FENE mediator.  She has served on the Minneapolis Civil Rights Commission and is a volunteer for Tubman.  She also serves as a Ramsey County and Hennepin County volunteer mediator.  She is also a member of the Association of Family and Conciliation Courts, Hennepin County Bar Association, Minnesota Bar Association, and Douglas K Amdahl Inn of Court and is a former member of the Minnesota Association for Justice. She serves as a mentor attorney for the University of St. Thomas mentor program.  She has presented various CLEs at the Hennepin County Bar Association on the topics of bankruptcy and divorce and discovery issues.  She recently presented at the Mitchell Hamline School of Law on the intersection of family law matters and tax issues.  She has authored articles on School Choice in Minnesota and Third-Party Custody matters.  Katie is on the bench and bar committee at the Hennepin County Bar Association working to bring the members of the bench in contact with members of the bar through education. She also serves as a volunteer investigator on the 4th Judicial District Ethics Committee.  

Katie has built a thriving family law practice with five dedicated family law attorneys and professional staff.  She believes that the practice of family law should be civil and treats all parties with respect even in the most acrimonious of disputes.  Katie handles hundreds of family law disputes annually.  She has received compliments from clients, the Court, and opposing attorneys as to her professionalism and competency in handling family law cases.  

Katie has settled many cases using mediation or the ENE process and when cases can’t settle, she has not hesitated to take cases to trial on a variety of legal issues including child custody modification, spousal maintenance, property division, parenting time, and custody, and division of assets and debts. Katie also appears periodically before the Minnesota Court of Appeals and has argued the topics of child custody modification, child support, parenting time, spousal maintenance, domestic abuse, and property division to the Apellate Court.  

Katie lives in Bloomington with her husband Mike, their two children, and one dog.  She enjoys running, working out, cooking, and reading mystery novels.
