Dr. Kaiser lives in Aberdeen with his wife, Becky and their 4 children: Grace, Lincoln, Luke and Evalyn. He enjoys spending time with his family, outdoor activities and attending Green Bay Packers games in the fall.


Dr. Joseph Rigg

Dr. Rigg (…the Dentist) and his wife Kris have made Aberdeen their home for the past 33 years. They moved here from Lincoln, NE upon graduating from the University of Nebraska College of Dentistry in 1988. They then began both his dental practice and raising their family. They have four beautiful daughters (Maire, Mairghread, Erinn, and Fionualla). They have three son-in-laws now as well (Jon, Michael, and Dyllan).

Dr. Rigg’s hobby is also his profession. Do what you love and love what you do. Kris loves to scrapbook and has accumulated quite a variety of very organized memory books as a result. Kris has functioned in a variety of capacities within the practice over the years acting as an assistant, front office staff, bookkeeper, and a janitor as the needs of the business dictated. She taught preschool and special education until the arrival of their first child. She has been the consummate home maker ever since. Their girls have also taken a turn spending time helping out over the years in the office. It has become and remained very much a family practice in that regard.

Dr. Rigg’s move over and in with Family Dental feels a very natural one. He and Kris feel it will be beneficial to themselves, their patients, as well as for Family Dental. Dr. Rigg has no plans to retire and is looking very much forward to a long, pleasant journey along this new path.

Dr. Shelby Roney

Dr. Shelby Roney, a native of Oakes, ND, brings a deep-rooted commitment to compassionate dental care. After completing her undergraduate studies in Biology and Chemistry at North Dakota State University, she pursued her passion for dentistry at Creighton University in Omaha, Nebraska, earning her Doctorate of Dental Surgery.

Outside of her professional pursuits, Dr. Roney finds joy in gardening, the art of sourdough making and cherishing moments with her beloved dog, Lottie. She also likes to help her dad on the farm, especially with the cattle.

With a heart for community service, Dr. Roney is thrilled to extend her expertise and dedication to the patients of Family Dental Care, where she looks forward to fostering healthy smiles and lasting relationships.
