Welcome Landmark Credit Union Members to the Greylock Family!
Please note that the Landmark to Greylock data conversion has been completed. Landmark Credit Union members may now utilize their new Greylock Checking accounts, Greylock VISA Debit Cards and enroll in the Greylock iBanking platform. Greylock VISA Debit Card members please note that, if you haven't done so already, you will need to activate your new cards by calling the activation number on the card. New iBanking users will need to follow the authentication enrollment process to activate access. Access is available right from the Greylock website homepage. Greylock Member Service and Contact Center representatives will be available Monday morning beginning 8:30 a.m. by calling (413) 236-4000 for any issues or concerns. Thank you!
