Many who know him (colleagues and clients alike) see Sam as a modern-day Columbo.  Anyone watching TV in the 70s and 80s undoubtedly remembers the popular crime drama featuring the friendly and deceptively clever detective who hid his true thoughts and intentions until the end of the case; and who, like a dog with a bone, never gave up until he successfully manipulated the results to his satisfaction.  In his years of experience practicing family law in McHenry County, Sam has developed a deep understanding of how to use the legal process to his client’s best advantage. While he might not use Columbo’s famous catchphrase “oh, uh…just one more thing” when working on a matter, his astute and tenacious way of practicing law are reminiscent of the infamous lieutenant.  

With expertise in different areas of law, Sam nevertheless considers family law (particularly divorce) and estate planning to be the most rewarding and challenging.  Having been through a divorce himself, he understands how devastating, difficult and costly a divorce can be and why it is crucial to have experienced legal representation to help navigate the divorce process and avoid pitfalls that just end up costing more money, creating aggravation, and delaying the process.   

Sam identifies with the struggles and concerns of each and every one of his clients.  Because he knows that the divorce process can be emotionally and financially draining, Sam and his team dedicate themselves and their practice to making legal options simple, understandable and digestible for every client, providing clear-cut legal advice and one-on-one support each step of the way. 

Sam and his team consistently go above and beyond to provide personalized counsel designed to help families take that next step forward.
