Editor's Review
VerifiedLawFirms editorialFocus and practice areas
This is a family law firm based in Naperville, Illinois, with a second office in Aurora. Keller Legal Services centers its work on the matters that family cases raise: divorce, child custody, child support, and maintenance, which older statutes and many clients still call alimony. The firm also takes on paternity, guardianship, orders of protection, and the property division that a separation forces.
Each of those areas carries its own weight. Orders of protection move quickly and often start in a moment of risk. Property division asks a court to split what a couple built, which is rarely simple. A firm that lists all of these together signals that it handles the full arc of a family dispute rather than one slice of it.
The work reaches past family law. Keller Legal Services lists real estate and business law among its services, and its navigation points to construction law and mechanic's liens. A mechanic's lien lets a contractor or supplier claim against a property when a bill goes unpaid, so that line of work ties real estate and construction together. As a reviewer, I read the mix as a general civil practice organized around a family law core.
The attorney who started it
Jeffrey S. Keller founded the firm in 1994. Before that, he spent five years as an associate at the national firm Keck, Mahin & Cate, between 1989 and 1994, where his work covered litigation, real estate, and corporate law. He earned his J.D. from Illinois Institute of Technology Chicago-Kent College of Law in 1990. Before law school he studied accounting at North Central College and finished a B.A. in 1985.
He was admitted to the Illinois bar in 1990 and to the U.S. District Court for the Northern District of Illinois in the same year. His own practice covers litigation, divorce and family law, real estate, and business law, which lines up with the firm's overall range. The accounting training is worth a note. Divorce and support cases often turn on income, valuation, and the arithmetic of dividing assets, and a grounding in the numbers can help on that side of the work.
How the team is built
Keller Legal Services names more attorneys than its founder alone. The group includes Michelle Chang, Rachel Keller, and Raleigh D. Kalbfleisch, with Krista Carls and Adisa Krupalija listed as of counsel. An of-counsel arrangement usually brings a lawyer's focused experience to a firm without full partnership, which lets a smaller office reach a wider set of matters than its headcount might suggest.
The named attorneys
Rachel Keller earned her law degree from the University of Kentucky College of Law. Raleigh D. Kalbfleisch holds a Bachelor of Science from Purdue University and a law degree from Quinnipiac University School of Law, which she completed in 2001. Her work covers family law, probate, guardianship, and appellate matters. She has served as a Guardian ad litem in the Eighteenth Judicial Circuit and in Kane County, a court-appointed role in which a lawyer reports to the judge on a child's interests.
Of counsel
Krista Carls concentrates on divorce and separation, and she has handled child custody and mediation. Adisa Krupalija earned a J.D. from the University of Illinois College of Law in 2007, along with a B.A. and a B.S. from the University of Illinois at Urbana-Champaign in 2004. She previously worked as an associate at McDermott, Will & Emery, and her practice centers on business law, with added work in general civil and trial matters. Between them, the two of-counsel attorneys strengthen both the family law and the business law sides of the firm.
Where the firm practices
Keller Legal Services represents clients across DuPage, Kane, and Will Counties. It names Naperville, Aurora, Wheaton, and Bolingbrook among the communities it covers. Two offices, one in Naperville and one in Aurora, place the firm near the county lines where many of its clients live and where the relevant courts sit.
In my opinion, the geography suits the work. Family, real estate, and construction matters are local by nature, tied to specific homes, projects, and courthouses. A firm working across the western suburbs can appear where those cases are heard. The second office in Aurora gives clients in Kane County a nearer point of contact than a single Naperville address would offer.
What a reviewer takes from it
Keller Legal Services is a long-running suburban firm with a family law core and a civil practice around it. The founder's record runs back to 1994, and the site names a working group of attorneys, several with their own areas of focus and prior experience at larger firms. The set of practice areas is broad for an office of this size, yet the pieces connect. Family cases raise property questions, and those questions run into the same real estate and construction ground the firm already works.
For someone weighing a divorce, a custody question, or a related civil matter in DuPage, Kane, or Will County, the firm gives a plain account of what it does and where it does it. That clarity, backed by named attorneys and a stated history, is the kind of detail this directory looks for.
