Marc A. Bangser

Marc A. Bangser, Partner

Marc is a Partner at Conniff & Keleher, LLC. and practices in all areas of divorce and family law in Cook, DuPage, Lake, Kane, McHenry and Will Counties, and focuses on negotiating and litigating a wide variety of pre-decree divorce matters, including high net-worth individuals and complex marital estates, post-decree modifications, child allocation and parentage matters, child support, orders of protection, and various other family law matters.

Marc believes that the first goal in any family law matter should be to try and work out disputes through negotiation and agreements, while keeping the parties out of the courtroom if possible. However should litigation be necessary in a contested family law matter, with his extensive experience from thousands of combined hearings, bench trials, and jury trials during his time as a family law attorney and prosecutor, Marc has earned the highest of accolades regarding his skill in the courtroom, his negotiation skills, and his excellent relationships with the judiciary and court personnel in numerous courthouses throughout the Chicagoland area.

As a parent of two young children, Marc knows first-hand that parents will go to great lengths to advocate on behalf of their children and to protect them. Marc also knows that children are often the most vulnerable and the most affected in family law matters. To that end, besides making a child’s best interests the top priority in any divorce or parentage matter, Marc has often been appointed by the Court in his capacity as a Guardian Ad Litem (GAL) to investigate and make recommendations concerning the best interests of children of a variety of ages and in a range of circumstances.

Because of his stellar work and reputation in the legal community, Marc has been named repeatedly as a Super Lawyers “Rising Star,” one of the Top 100 Matrimonial & Family Lawyers by National Advocates, and has received various other accolades reflecting his high character and skill in divorce and family law.
