Meet Our Staff
Kathy O’Hagan, RDH
Was born and has lived in Hartford all her life. After high school, always having an interest in dentistry, she attended MATC receiving a diploma in dental assisting. She worked in this field for five years. Eventually a family business took her on another path until returning to MATC to receive a degree as a Registered Dental Hygienist. The Hartford Dental Group proved to be the caring practice with the ideals and talented staff that has set her roots. In her 23 years with the HDG, friendships with patients continue to evolve, always striving to give her best to all. While pursuing this career, encouragement comes from her husband Mike, children Casey, Shane, and Brooke, grandsons Peyton and Kendrick, and granddaughter Kinley. When not caring for family and home, she can be found trail riding in the Kettle Moraines and nearby parks with her friend, Mac.
