CSI Member Directory

CSI’s Member Directory contains contact information for thousands of construction professionals who belong to the Construction Specifications Institute. It is available only to CSI members in good standing. Search for a CSI member by name, company, location, CSI chapter or CSI Certification!

Current CSI members can log in to this app using the same username and password they use when accessing CSI’s Member Directory at www.csinet.org. Not sure what your login is? Contact CSI Member Services at csi@csinet.org.
