Gregory Rush, a former executive with Siebel Systems, is the new corporate controller at Tekelec.

Rush will be based in Morrisville. In April, Tekelec announced it is moving its corporate headquarters to North Carolina from Calabasas CA.

“He has significant financial and accounting skills, as well as proven leadership in SEC reporting and Sarbanes-Oxley compliance and significant experience working with and leading finance organizations in the high tech industry that will be of great value to Tekelec,” said Bill Everett, Tekelec’s chief financial officer.

Rush earned his masters of accounting degree at UNC Chapel Hill.
