Dr. Olshausen is a board-certified Internal Medicine physician. A German native, he earned his MD and a PhD in neuropharmacology from the Humboldt University of Berlin. He then relocated to the United States in 2003. He completed his 3-year Internal Medicine residency at Yale University and the affiliated Norwalk Hospital in Connecticut and added on a fourth year as Chief Resident, graduating from the program in 2007.

He kicked off the adventure of practicing medicine as a fully trained Internist in the Rogue Valley where he has been living with his family since 2007. Here, he has been offering primary care services and in addition to the management of chronic diseases, he focuses on a preventative approach to medicine and patient education, which includes healthy lifestyle choices, cancer/disease screening and vaccinations. Dr. Olshausen provides care for patients ages 18 and older.

After 10 years on the front lines of treating patients, the practice of medicine for him needed to return to the patient-doctor relationship instead of the dysfunctional patient-insurance-doctor entanglement which led to his switch to the Direct Primary Care practice model and the opening of his own practice and business, Rogue Direct Primary Care.

“I am passionate in my belief that this change to Direct Primary Care will provide my patients with the care they truly deserve since this model can provide a quality of medicine that we may have come to believe was out of reach.”

Dr. Olshausen couldn’t have been successful nor embarked on this new professional adventure without the love and support of his wife, 2 young boys and the eager distraction of the family’s two dogs.
