About me

Cecilia Hynes Griffin ("Leah") is a graduate of the University of Notre Dame and holds a law degree from Loyola University in Chicago. Leah began practicing law in 1990 at Rudnick and Wolfe, now known as DLA Piper, in the areas of environmental and real estate law. Since 1993 she has practiced family law exclusively and, in 2003, formed Griffin & McCarthy, LLP, as one of two founding partners. Now known as Griffin McCarthy & Rice LLP, the firm is a boutique law firm practicing exclusively in the area of family law. With offices in downtown Chicago, Burr Ridge and Lincolnshire, Griffin McCarthy & Rice LLP handles cases in Cook County, DuPage County and Lake County.


With over 22 years of experience in family law, Leah has handled amicable straight forward agreements as well as numerous complex family law matters, including multifaceted business valuations, income determination issues, dissipation claims, tracing of marital and non-marital assets, as well as custody, visitation and removal disputes.


Leah has been nominated an Illinois Leading Lawyer and an Illinois Super Lawyer in the area of Family Law from 2008-2014. She is a Fellow in the American Academy of Matrimonial Lawyers. Admission to this national organization requires extensive oral and written testing, and peer and judicial recommendations. Leah presently is Vice President of the Illinois Chapter of the Academy and serves on the Family Law Section Council of the Illinois State Bar Association. She is also past editor of the Section’s family law newsletter. She is a frequent lecturer and has authored numerous articles on family law topics.



Leah has extensive litigation experience and has been a faculty member at the prestigious Houston Family Law Trial Institute teaching other family law attorneys advanced courtroom skills. She also has been hired as an expert witness in family law matters. Leah is a trained mediator, is a practitioner of collaborative law and is a member of the Collaborative Law Institute of Illinois. In addition, Leah was recently selected to be on the list of approved mediators for financial and custody related matters by the Circuit Court of Cook County. Utilizing these various skill sets, Leah has a strong track record of successfully negotiating and settling cases but also has the experience needed to effectively advocate for the client in the courtroom when necessary and as a last resort.
