LIMA — U.S. Rep. Pat Tiberi, R-Worthington, participated Tuesday in a roundtable discussion with administrators of St. Rita’s Medical Center and Lima/Allen County officials. Tiberi, who chairs the House Ways and Means Subcomittee on Health, said the purpose of the visit was to hear the challenges and concerns of local health care professionals. “When I became health chairman, I realized I should get a better understanding of the challenges Ohio hospitals have,” Tiberi said.
