Meet The Doctors

Dr. Greg Killian

After graduating from the University of Iowa, Dr. Killian opened his practice in its current Middleton location in 1978. Over the years, Dr. Killian has overseen expansion of our clinic from a two-treatment-room office to the current, modern, nine-treatment-room, 5000 square-foot, state-of-the-art facility. He is passionate about staying with the latest trends. In the past three years, Dr. Killian received over 250 hours of continuing education from leaders in postgraduate education, including LVI and Gordon Christensen Clinical Research Associates. His continuing education has focused on diverse aspects of dentistry, including conscious oral sedation, cosmetic dentistry and restorative dentistry, dental implants, and full-mouth rehabilitation. In 2009, Dr. Killian was selected as a restorative advisor for the prestigous Seattle Dental Study Club.
