As an expert in osteopathic medicine, Helgerson takes a holistic, wellness-oriented approach to health care and can use osteopathic manipulation to help remove impediments to the body’s ability to heal itself. In practice, some osteopathic physicians use manipulation techniques frequently while others treat their patients through more conventional medicine.

Osteopathic medicine is a distinctive form of medical care founded on the philosophy that all body parts are interrelated and dependent on one another for good health. Osteopathic physicians use a more gentle approach of manipulation that involves mobilizing joints and stretching.

In addition, Helgerson’s family practice interests include women’s health, obstetrics, pediatrics and dermatological procedures.

“Family doctors have a unique opportunity to care for the whole patient through all stages of life. I believe that the health of our mind, body and spirit are all interconnected. I also believe the body has the capability to heal itself if provided with the right tools.”

Outside of medicine, she enjoys gardening, hiking, kayaking and camping. Dr. Helgerson lives in the area with her husband.
