About Hillcrest Dental


We're Your Dental Home,
Close to Home.

Originally an onion farm, Hillcrest Dental Center came about as the vision and desire of its founding doctor, Raymond G. Klockow, DDS. A local dentist who at the time ran a practice with the Clinic of Family Medicine, Dr. Klockow sought to establish a family-based practice north of Rensselaer that would be easily accessible to several communities in and out of Jasper County.In 1997 the practice expanded with a broader variety of services and longer hours of operation.

A second dentist was also hired, John Ahler, DDS, a local resident of the community. By 2001, Hillcrest had grown in staff and patients, making a renovation of the grounds and clinic necessary.

The upgrade resulted in a nearly 8,000-sq. ft. clinical facility, complete with 10 operatories, surgical suites, conference rooms, and impressive office space with state-of-the-art equipment. Following the renovation Hillcrest won the 2002 Excellence in Design Award from Tillet Construction (now Titan Construction).

As Hillcrest continued to grow, 2011 saw yet another addition of a third dentist, Jack Drone, DDS, a local county resident. Drs. Ahler and Drone now direct their efforts and energy toward providing comprehensive, quality care in one location close to home. The Hillcrest priority is to provide the highest standard of oral healthcare and beautiful smiles.
