ANS’s Mentor Match applications open
Applications are now open for the American Nuclear Society’s newly redesigned mentoring program. Mentor Match is a unique opportunity available only to ANS members that offers year-round mentorship and networking opportunities to Society members at any point in their education.
The deadline to apply for membership in the inaugural summer cohort, which will take place July 1–August 31, is June 20. The application form can be found here.
ANS has made every effort to secure the best possible nightly room rate for you at the Chicago Marriott Downtown. That rate results from a negotiated overall package of event needs including but not limited to sleeping rooms, meeting room space and other requirements.
Please help ANS keep the costs of this event as low as possible by booking your housing needs at the host hotel and through the reservation process created by ANS. Reserving your rooms elsewhere means you are booking outside the contracted room block, jeopardizing ANS’ ability to meet its contracted obligations. Unfortunately, if this happens, event costs will continue to increase if ANS falls short of its minimum room block guarantee. ANS appreciates your support and understanding of this important issue. Thank you!
