Nicholee Theiss, MD


Dr. Nicholee Theiss is a board-certified family medicine physician, and therefore treats a very wide range of acute and chronic conditions for patients of all ages. She holds an undergraduate degree in biology and chemistry from the University of Wisconsin – Stevens Point and received her medical degree from the University of Wisconsin Madison Medical School in 2002. She went on to complete her internship and residency in family medicine at the University of Wisconsin Hospitals and Clinics, where she was elected chief resident.

She has held academic appointments at the University of Colorado and the Red Rocks Physician’s Assistant Program.

Having grown up on a farm in rural Wisconsin, Dr. Theiss has a special love of animals and the outdoors. She is a long-distance runner and enjoys hiking, camping, skiing, reading, and traveling with her family. Dr. Theiss has a special interest in teaching, preventive care for people of all ages, as well as full spectrum pediatrics, endurance athletics and women’s health.

Unlike other physicians who specialize in treating one organ or disease, family physicians are uniquely trained to care for you as a whole person, regardless of your age or sex. If a health condition arises that requires care from a specialist, Dr. Nicholee Theiss will be there to guide you and to coordinate all aspects of your care. Dr. Theiss says that the secret of her success is the collaborative approach she takes with her patients. This means treating them with respect and dignity at the same time as educating them about their health and conditions and encouraging them to take an active role in the management of their own health. She believes in working together to achieve the best possible outcome for each patient.
