With this unique training he has continued using advancements in dental technology to increase the comfort of his patients in the chair. His main focus is on prevention, an area in which he lectures frequently. He can be seen teaching throughout the Chicagoland area at one of his sought after programs dealing with juvenile dental health and anxiety. He is known for his hands on approach, working with Kids to reduce anxieties and fear about going to the dentist. His core beliefs include fostering early education to lay the groundwork for healthy teeth for life. Dr. Sam Weisz has implemented the use of Computer Guided Implant surgeries in conjunction with a process called conscious sedation to make his Libertyville dentist office a more comfortable and less scary place to be. His first project post residency, was as editor to the dental education publication, “Things You Should Have Learned in Dental School and Never Did”. Dr. Sam Weisz’s main goal in dentistry is to make the dentist less scary and create a new kind of smile for the patients at Libertyville Dental Associates.

Dr. Weisz remains dedicated to providing dental care to under served populations both at home and abroad. He has gained a unique perspective on life in places in which there are few or no dentists, through his work with migrant farm workers of the southwest, isolated populations of Yucatan Mexico’s village communities, and the U.S. war veteran population. In his free time, Dr. Weisz has a fondness for anything adventurous, from hiking and whitewater rafting to amateur boxing and fishing.

Dr. Weisz takes great pride in caring for his patients with a gentle hand and caring smile. Most of all, Dr. Weisz, is excited to bring his energy and enthusiasm to Libertyville Dental Associates. He believes strongly in our practice philosophy and looks forward to meeting our patients.
