John Porter was born in Birmingham, Michigan. A graduate of the University Of Michigan, John Porter was working as one man insurance adjusting firm called "Chaos Reductions." This firm was in direct competition with Damage Control and so Anne-Marie Hoag offered him a job and a salary he could not refuse. He has a tremendous knowledge of insurance law and has a knack for always finding the simple solution to any problem. At times he's been romantically linked to Robin Chapel.
