ABOUT US
We are saddened to announce that Mr. David E. Hoy has passed away in December, 2025, but joyful that he is safely home with his Lord and Savior, Jesus Christ. His obituary may be viewed at this link.
In 2025, David celebrated 40 years of running the Law Offices of Hoy & Sahlas, LLC, a successful, father-daughter law firm with his daughter and law partner of 25 years, Colleen L. Sahlas. His daughter, Mrs. Colleen L. Sahlas, continues his legacy of treating each client with compassion and care and each case matter with experience and integrity.
Originally founded in 1985 as The Law Offices of David E. Hoy, our firm was located in Oak Park for 23 years. In 2000, Attorney Colleen L. Sahlas joined her father's firm. In 2006, we became the Law Offices of Hoy & Sahlas. In 2008, we relocated to the central Chicago-land suburb of Oak Brook, Illinois, just 20 minutes west of downtown Chicago.
Attorney Sahlas was mentored in the law (and life) by her kind, patient and knowledgeable father, David E. Hoy, and stands on the shoulders of her father carrying on the law firm he founded. Having over 25 years of experience as an attorney, Attorney Sahlas is a published author, speaker, leader and an authority in Illinois estate planning and decedent's estates. She is the General Editor of "Practical Probate," a 1,000+ page manual for attorneys published by the Illinois Institute for Continuing Legal Education. She is the winner of the 2025 Outstanding Achievement in Estate Planning Award by IICLE. She strives for excellence in her work through continuing legal education courses, serving on legal Councils and Bar Associations to keep abreast of ever-changing laws and current legal practices. Unlike high-powered, large, impersonal firms, our family-oriented firm is friendly, approachable and trustworthy. We provide “hand-holding,” and empathy through the entire legal process. Our goal is to be personable and make clients feel like family. We are committed to integrity, diligence, and high-quality legal services.
Our firm represents clients in Cook, DuPage and Kane Counties in Illinois.
We acknowledge that all good gifts and abilities come from our heavenly Father. We’re grateful to the Lord for the opportunity to serve and glorify Him through our work.
