O'Leary Dental

For nearly four decades, Dr. O’Leary has been providing comfortable, high-quality dental care to the Southern Wisconsin region.  As a Janesville native and Parker High School graduate, Dr. O’Leary has deep roots in the area and a commitment to its residents.  After earning a degree from Marquette University and gaining advanced cosmetic training at the Las Vegas Institute (LVI), Dr. O’Leary chose to build a private practice with a cozy, welcoming atmosphere.

His Practice was founded on the belief that a positive dental experience is built on trust, not rushed appointments.  Patients receive personalized, gentle care across a broad range of services, from general family dentistry and root canals, to dentures and advanced procedures like implant placement, full mouth reconstructions and cosmetic treatments, including Botox and Juvéderm fillers.
