Our Philosophy

Mr. Millar is a strong advocate of equal shared parenting in Missouri custody cases pursuant to H.B. 1550 (2016) and Morgan v. Morgan, 497 S.W.3d 359 (Mo.App.2016).  He is a registered lobbyist with the Missouri Ethics Commission and frequently testifies in front of both Missouri House and Senate Committees in support of a rebuttable presumption among fit, willing and able parents for equal or approximately equal parenting time.  In 2018, he testified in favor of HB1667, a follow-up bill to HB1550 (2016); in 2019, he testified in favor of SB14 and HB229; in 2020 he testified in favor of HB1765 and SB531; and most recently in 2021 he testified in favor of HB299, HB1315 (relating to Guardian ad litem reform), SB199 and SB459.
