How To Become An Approved Vendor Representative

In accordance with Memorial Hermann Vendor Management guidelines, all Memorial Hermann campuses require vendor representatives and agents seeking access to be properly credentialed. Before a representative or agent may be credentialed, a company must be vetted and approved. To become an approved vendor for Memorial Hermann, Supply Chain Management must receive a formal "formulary" request from a credentialed physician within the healthcare system for all medical supplies. A current employee within the system must submit a "vendor addition" request for all other vendor types. Additionally, the vendor must complete a due diligence application via our online website. Once these two items are completed, a member of the Supply Chain Management department will notify you as to the status of your application. This is the only process to become an approved vendor for Memorial Hermann.


Once a request has been received by the Supply Chain Department, either from a credentialed physician or a current employee within the healthcare system, an automated email will be sent to a representative of the company.

Your company will be required to provide specific information about the company via our secure website. An id and password will been generated for the secure site in order to submit the requested information. The information submitted will be reviewed by Memorial Hermann and a determination will be made as to the acceptance as an approved Memorial Hermann vendor. You will receive notice of approval or rejection (with explanation) once a final determination has been made.

To find out if you are an approved vendor with Memorial Hermann, please contact
