Jennifer Guimond-Quigley

Managing Attorney


Jennifer is the owner and managing attorney at the Law Office of Jennifer Guimond-Quigley.  She realized early on in law school that she had a passion for family law and estate planning. After gaining experience in these two areas both during and after law school, Jennifer decided to start her own firm. With her solo practice, Jennifer loves having the freedom to collaborate with her clients to achieve the best results possible without the limiting constraints common to practicing with larger firms.


Jennifer has an extensive background in business and accounting, which has been invaluable in her legal practice. She spent years working as an accountant, and that experience has been imperative in counseling her clients about the financial and tax impact of their decisions and agreements. Jennifer’s comfort level with numbers allows her to easily explain their complexities in a relatable way to her clientele.


Jennifer was named a Rising Star by Super Lawyers Magazine in 2016, 2017 and 2018 in the areas of Family Law and Estate Planning, a designation reserved for the top 2.5% of all Illinois Attorneys Under age 40.  She was also a recipient of the Top 10 Under 40 Award from the National Academy of Family Law Attorneys in 2017.  Jennifer is a member of the Illinois State Bar Association and the Chicago Bar Association. She also founded Flying Solo Chicago, a collaborative group for attorneys with solo and small firms.


Jennifer resides in Chicago with her husband and children. When she’s not practicing law, she enjoys spending time with family, cooking and donating her time to various charitable organizations.
