CHA develops and conducts a variety of programs and events each year to support Catholic health care in the United States. Additionally, other organizations conduct programming that is relevant to the concerns of Catholic health care. While many of our programs are open to nonmembers, some CHA events are open only to members. Some are by invitation only. If you have any questions about the programs listed on the Calendar of Events, please contact webteam@chausa.org. If you have any questions or issues with registering for a program online, please contact servicecenter@chausa.org.
