Dr. LaTulippe had his medical license revoked by the Oregon Medical Board in December 2020 after he did not wear a mask at his clinic and engaged in alleged “unprofessional conduct or dishonorable conduct,” according to the emergency suspension. LaTulippe told patients who believe they had COVID-19 or were showing symptoms of the virus to wear a facial covering, and saw these patients at the end of the day at his practice, according to published reports.
