4106 W Crystal Lake Road A Route 120 doesn't let your sign go unnoticed. That's the point. This first-floor suite at 4108 W Crystal Lake Rd sits inside a masonry building that has housed working professional practices in McHenry for years. The kind of address that tells a client something before anyone speaks. The suite is fully built-out. Industrial carpet, neutral interiors, nothing waiting on you. 972 square feet, available immediately. For a practice that needs to be open and accessible to clients from day one, this is where you land. New parking lot paving in summer of 2026.
