Dentistry provided in a warm and caring environment is what you will find at the office of Dr. Karen O’Rourke. The patients in the practice cover a wide age range; from infants to seniors. In practice for 21 years, Dr. O’Rourke has a broad range of experiences you will value as a patient. She has avidly pursued continuing education, bringing a preventive orthodontic exerciser to her patients from Australia for children as young as three. The orthodontic treatment she provides is based on appliances developed in England. The benefit of this particular treatment is that it strives to correct the cause of the problem, not just straighten teeth. For adults, she has pursued education in cosmetic dentistry, full reconstruction, and implants to replace missing teeth.
Dr. O’Rourke graduated from the University of Michigan and then completed an optional one year General Practice Residency at the U of M hospital. This residency training took her through the eight dental specialties as well as rotations through the hospital. Emphasis was placed on treating medically compromised patients, oral cancer patients, and patients requiring dentistry under general anesthesia.

She taught for a number of years in the hygiene program at GRCC and is involved in a number of community and professional organizations. Dr. O’Rourke is on staff at St. Mary’s Hospital and Mary Free Bed Rehabilitation Center. In addition, she is a Fellow of the American Association of Hospital Dentists and a member of the American Dental Association. Thankful for the gifts she has received, Dr. O’Rourke gives back to the community by volunteering at Clinica Santa Maria, the Adult Dental Services Program, and the Donated Dental Services Program of Michigan.
