We are Southern Illinois – serving Madison County, St. Clair County, Monroe County, Randolph County, Washington County, Perry County, Bond County and beyond.  


Greensfelder's Southern Illinois office was established in 1995. For the past quarter-century, our attorneys have had the privilege of serving clients that range from world-class closely held business owners to exceptionally humble high-net-worth families and individuals from O’Fallon, Shiloh, Fairview Heights, Belleville and throughout Southern Illinois with business and personal estate planning needs. Clients tell us they appreciate our reputation for bringing full-service, deep legal expertise and personalized relationship attention without over-lawyering or surprising clients with rates and invoices they aren’t expecting.

Our strengths include:

Banking and Financial Services 

Southern Illinois banks and financial institutions are among our most collaborative alliance partners as we serve executives, loan officers and trust officers helping them grow and protect their revenue and serve their customers well.

Real Estate

We serve enterprising and growth-minded real estate developers and hardworking, ethical contractors helping them get their deals done and resolving disputes to get results they want. Our real estate work also places us as a first call for municipalities, multi-generational landowners and high-integrity school districts eager to have their real estate projects match their commitment to providing the best education to children of Southern Illinois.

Southern Illinois Litigation

We have a storied track record of trial success defending national companies when they have litigation representation needs in Southern Illinois. We relish our marquee, Fortune 500 company relationships as lead and local litigation counsel to the largest law firms in the country.

Closely Held Businesses and High-Net-Worth Families

We are partners with closely held businesses and private clients, helping them to grow and strengthen their finances, families and futures. We know what closely held businesses, multi-generational families and high-net-worth individuals need, and we have the capability to navigate sophisticated matters with a sensible and flexible approach. Using this, we approach our role with empathy and compassion for each unique situation. Our team frequently operates in one or more capacities as outside general counsel for closely held businesses, family counsel, and tax counsel.

Clients and referring law firms tell us that Greensfelder’s Southern Illinois office brings the right combination of legal excellence with intimate, local market fluency to serve client needs within the judicial epicenter of Southern Illinois. This includes Madison County, St. Clair County, and the counties comprising the 4th and 5th judicial districts and Southern and Central federal district courts. When referred as local counsel, we mirror the same client experience expectations as the referring firm, creating a seamless service experience for the clients.
