Justin C. Nidiffer

“Be sure you put your feet in the right place, then stand firm.”   – Abraham Lincoln

Justin C. Nidiffer was born and raised in Xenia, Ohio.  After graduating from high school, Justin received a baseball scholarship to Ohio Dominican University in Columbus, Ohio.   He went on to complete his undergraduate studies at Wright State University where he majored in Accounting and received Dean’s List honors on multiple occasions.  From there, Justin moved on to the University of Dayton School of Law where he was a Dean’s Scholarship Award recipient.  While at the University of Dayton, Justin worked in the school’s law clinic where he helped indigent members of the community navigate complex legal issues.  He also completed an externship with the Greene County Court of Common Pleas Domestic Relations Division. 

After law school, Justin returned to the Greene County Domestic Relations Division and served as the court’s staff attorney for nearly two years.  He then made the jump to private practice, joining a reputable general practice firm in Xenia, Ohio.  While there, Justin handled primarily family law matters, but also a variety of criminal and civil matters as well.  Eventually, Justin decided to focus his practice solely on family law and that is what brought him to Kirkland and Sommers in 2019.  In addition to his work as an attorney, Justin has served as a guardian ad litem for over one hundred children, representing their best interests in custody battles in Montgomery County and Greene County.

Justin is the former President of the Greene County Bar Association and co-chair of the Family Law Section of the Dayton Bar Association. Justin sits on the Greene County Bar Association’s Judiciary Committee and is the Chairperson of the Greene County Bar Association’s Scholarship Committee.  He resides in Beavercreek with his Wife and kids.  He is a diehard Cincinnati Reds fan and loves to golf.
