Virtual Early Career Luncheon at the IEP Workshop - Looking for Volunteers!

This year we would like to expand the reach of the early career luncheon to our virtual attendees of the annual workshop. Generally, we have an in-person luncheon for a small group of participants during the workshop. We'd like to offer the luncheon to our virtual participants as well this year, but we need volunteers to help run the virtual event. The event will be held on Tuesday, April 23 from 12:25 p.m. to 1:55 p.m. As a volunteer, your participation will primarily involve hosting a Teams or a Zoom meeting with breakout rooms and helping people move between the rooms, as needed.

If interested in volunteering, please contact Kristi Arend at karend@usbr.gov.
