A new Platteville Common Council member was appointed Tuesday night. By a 4-2 vote, council members selected Jason Artz to fill a seat vacated earlier this year. Artz, who is a mental health counselor at University of Wisconsin-Platteville, will fill the at-large seat vacated by Cena Sharp, who resigned July 11th . The term runs through April 2021. Five candidates applied for the position, and council members interviewed them earlier this month.
