Kierstin Lorenz, DDS
Dr. Kierstin Lorenz is from North Dakota and graduated with her Bachelor of Science Degree in Biology and Health Sciences from the University of North Dakota. She received her Doctor of Dental Surgery (DDS) degree from the University of Minnesota School of Dentistry. Along with being an active member of the Washington-Ozaukee County Dental Society, she is a member of the American Dental Association, Wisconsin Dental Association, and the Academy of General Dentists.
Dr. Lorenz practiced dentistry in Tucson, AZ, before moving to Wisconsin to be closer to her husband’s family. She also practiced in the Franklin area before taking over Lake Five Dentistry in early 2023. Being from North Dakota, she likes to joke that the winters in Wisconsin feel pretty balmy!
Dr. Lorenz is a general dentist who enjoys providing a gentle and relaxing dental experience for patients of all ages. She believes in taking the time to do things correctly and providing the highest-quality dental care.
Dr. Lorenz creates treatment plans as if she were working on her friends or family. She loves the details and artistry of dentistry and finds it exciting and challenging to figure out the “puzzle” in every toothache. As a result of this personalized care, she has created an environment where each patient can have their individual needs and concerns addressed, building long-lasting relationships with her patients.
Always seeking to continue her education, Dr. Lorenz attends annual seminars to stay ahead of the ever-changing dental world and provide her patients with the most current and effective care.
Dr. Lorenz spends much of her free time with her husband, Aaron, remodeling their mid-century home. Together, they also love to travel the world, making it a priority to explore somewhere new every year. They also have a new baby girl, Nellie, and two golden retrievers, Rosie and Taliesin, that keep them busy as well. Dr. Lorenz looks forward to working with you and your family!
