Great Lakes Dental Associates is locally owned by Dr. Shaun O’Neill and Dr. John Clay. It is comprised of three dental practices which have merged into one location. The expansion of the practices offers added convenience for our patients when scheduling appointments and the capabilities to provide comprehensive services through state-of-the-art technology. All original practices have deep-seated roots in Spirit Lake and Laurens.
Dr. Linda Bieri and her father, Dr. Miles Olson, practiced dentistry together in Laurens, IA, upon her graduation in 1978 from the University of Iowa College of Dentistry. Dr. Steven Christensen joined them in 1986, and the three practiced together for eight years. Drs. Bieri and Christensen continued practicing in Laurens and opened a satellite practice in 2005 in Spirit Lake, IA. Both locations have thrived due to the compassionate care provided to patients and the doctor’s and team members’ skills.
Dr. Janet Boyes graduated from the University of Iowa College of Dentistry in 2014. She acquired Great Lakes Dental Center in 2015 and has grown the practice through excellent patient care and compassion. Her passion for dentistry has developed a deep level of trust and loyalty from her patients. She and her team members embrace the same goal for the highest standards of care for their patients.
Spirit Lake Dental was established by Dr. Owen Nielsen. His son, Dr. Eric Nielsen, joined him upon graduation from the University of Iowa College of Dentistry. Upon his father’s retirement, he became the sole practitioner. The practice grew to serve many loyal patients, consisting of both local and summer residents. He and his team provided exceptional care to all patients, catering to their needs with empathy and respect. Dr. Nielsen retired in 2018, shortly after his practice was acquired by Applewhite Dental partners. In June 2021, Great Lakes Dental Associates purchased the practice, bringing in all original team members.
