Meet Our Dental Professionals

Crossgates Dental has been a cornerstone of oral healthcare, providing quality service and smiles to the Slidell, LA community. Dr. Deniger, the owner and lead dentist, has been the face of the practice since 1992. In February 2000, Dr. Deniger started offering dental implants to his patients. He traveled the country learning the various techniques of placing implants and bone grafting while mastering the small details to ensure implant success.

In 2023, Dr. Silvestri retired, but Dr. Deniger continues to practice full-time. Although he had no plans to retire soon, the time came to add another dentist to replace Dr. Silvestri. In June 2023, Dr. Deniger welcomed Dr. Preston Bivona to the practice. During this transition, he decided to entrust his life’s work to Dr. Bivona. Dr. Bivona’s knowledge, talent, passion, and patient dedication made him the perfect fit to carry on the practice’s tradition of excellence.
