La Crosse pediatrician arrested on charges of sexual assault of a child

A Mayo Clinic Health System pediatrician was booked in La Crosse County Jail on two counts of first degree sexual assault, with no bond.

Dr. Joseph Poterucha, 40, who practices at Mayo in La Crosse, was arrested Thursday, according to the La Crosse County Jail Inmate listing, and is expected to appear in court Friday afternoon. Poterucha is also part of Mayo's COVID team. 

A search for Poterucha on Mayo's website currently states "page not found."

The La Crosse Tribune has reached out to Mayo Clinic Health System for comment.
