Sempert’s pharmacist and owner, Michelle Petersen, R.Ph., is trained and ready to answer your health-related questions and provide council for your prescriptions. She can guide you through the maze of information available for staying and getting healthy! Sempert’s Drug, like any Good Neighbor Pharmacy is independently owned and operated by Michelle Petersen and Larry Lenihan. While Sempert’s Drug is able to offer the quality products and value pricing of the chain stores, the staff are your neighbors and they provide personalized service you’ve come to expect and deserve.
