About Streitz Dental

Learn more about our offices in Joliet and Plainfield

We are a dental team of a father and his two sons, first established in Plainfield and Joliet over 60 years ago. We are experts in all aspects of  dentistry, from patients with minimal needs to those who require more complex work. We pride ourselves on listening to our patients’ needs and developing comprehensive treatment options focusing on long term results. We dedicate hundreds of hours outside of the office to educating both ourselves and staff, in order to provide the best dental treatments available. Our practice is built on mutual respect and trust where we value the patient-doctor relationship – something we feel is rare today. Optimum oral health is our top priority, and we will care for you how we would care for our own family. If you are a new patient, we welcome you to join our practice where you can look forward to a lifetime of comfort, health, and beautiful smiles!
