Firm Details

Family lawyer Dean S. Dussias and business lawyer A. Thomas Skallas founded Dussias Skallas LLP in 2015 because, although we were already servicing our clients at the highest level, we realized we could be even better together.  With the addition of family lawyer Steven G. Wittenberg in 2016, Dussias Skallas Wittenberg LLP continues to attract entrepreneurial clients and recruit top legal talent with its innovative service model: assembling integrated teams of business and family lawyers to focus on each client’s full legal needs, rather than organizing itself into separate practice groups.
As trusted advisors to our clients, relentlessly focused on solving problems and getting the details right, we have built the Dussias Skallas Wittenberg LLP team by recruiting outstanding attorneys who like to think and act differently from the usual law firm rules.  When we say we are family lawyers who understand your business and business lawyers who understand your family, we are talking about an approach suited to today’s executives, entrepreneurs and high-achievers, for whom there’s no such thing as “regular business hours” and for whom work life and personal passions are very much intertwined.  We don’t organize ourselves into departments or practices, leaving you to figure out who you’re supposed to call with a certain question or passing you from lawyer to lawyer depending on the matter at hand.  Instead, we create teams of the right size and the right combination of skills and expertise to handle exactly what you are facing.  You have a single point of contact – and, because your team collaborates using the best cloud-based technology, you have the peace of mind that comes with knowing that everyone is up to speed.
Conventional wisdom has long held that family law practices kept their work entirely separate from business law.  But the complex business ownership structures, entrepreneurial ventures and dual-career families of the 21st century world defy these conventions, requiring expertise from the realms of corporate law, trusts and estates, family law and more.  In the past, clients who wanted all of this expertise around one table had to hire multiple firms or limit their search to a few super-size firms who claimed to be able to do it all.  Dussias Skallas Wittenberg LLP represents a new, better option: the expertise you need with the boutique-style attention you deserve.
We have structured our business around the way you live and work, combining the best people with the best technology to make ourselves your best advocates.
Dussias Skallas Wittenberg LLP practices in Cook, Will, Kankakee, Lake, Kane, Kendall and McHenry counties.
The firm has convenient locations in Chicago, Oak Brook, Tinley Park and Deerfield.
