You are being redirected to the Joint Membership Portal shared by the Microscopy Society of America and the Microanalysis Society. The portal site is still a work-in-progress, and you may not see the MAS logo on the login and renewal pages. However, new and renewing MAS members can use this site to handle all membership payment, charitable fund donations and profile updates. If you experience any difficulties with the portal, please capture a screenshot of the problem, and contact the MAS to resolve the problem.
Donations to the MAS Charitable Funds can also be made through the MAS website at any time, independent of the Membership Portal.
