Hello Joshua,

I know nothing about an RFP. I only hire direct employees for Aon (no agency or contingent workers).

Here is the information I believe you are seeking:

Tapfin is the managed service provider we use for vendors and process.  They hold the agreements with suppliers.  The contact person is Jon McCallum.  There is a general email used for questions:  tapfin@aon.com.    I also have Jon’s contact information:

Jon McCallum | Program Professional
Aon Service Corporation | Contingent Worker Program
P: 224-622-9038
jonathon.mccallum1@aon.com 


Warm regards,

Kelli Aker  |  Sourcing Team Manager – ASC, IT & Executive
