Attorney
Olivia Long
Olivia founded O. Long Law after seeing too many firms leave clients without the information they need to make good decisions in a divorce. She pairs litigation experience from large law firms with a no-nonsense approach to protecting families, seeking mediation and negotiation where possible and fighting hard where it isn't. Clients know her for straight answers, clear options, and creative legal solutions.
I want clients to know they can get closure after a dispute: they can be financially secure, and their kids will be ok.

Biography
Olivia noticed that too many firms do not provide clients the tools they need to make good decisions in their family law disputes. She wanted to correct that. In divorce, clients should have information and support so they understand the process and don't feel intimidated into making deals just to get things over with. With considerable litigation experience gained from working in large law firms, a command for high-stakes negotiation, and a no-nonsense approach to protecting families, Olivia founded O. Long Law.
Often praised for her straight answers, clear options, and creative legal solutions, Olivia leverages her skills to assist people going through the trauma of divorce, domestic violence, and disputes involving custody and child support. Whenever possible, she seeks opportunities for mediation and negotiation. But Olivia is an aggressive advocate who's always ready to fight for her clients, their children, and their financial well-being.
In college, Olivia was a letterwinner in rowing and a Big XII Scholar-Athlete. She enjoys singing and can often be found helping to stage the musical benefit show at the Woman's Club of Evanston. She lives in Evanston with her wife, kid, two cats, and a pit bull named Westside. Olivia also enjoys traveling the world to watch her stepson compete in karate.
