Michael Westgarth
Claims Advocate - Treaty Reinsurance
London, UK
Mike is a Claims Advocate in our Reinsurance team, working on both Treaty and Facultative lines of business. He works with clients, brokers, and reinsurers to assist with all claims related matters.
Mike has been involved in reinsurance claims for 33 years, working on both Non Marine Property & Casualty Treaty claims, starting at Greig Fester in 1989 as a claims technician/broker. After leaving Greig Fester, he had a 7 year period working as a claims adjuster at both Sphere Drake/Odyssey Re & Lexington, before returning to claims broking for Denis M Clayton in 2000.
If Mike was not working for McGill and Partners, he would be trying to breathe new life into old, unloved cars & motorbikes.
“I joined McGill and Partners for a new challenge, as the opportunity to get involved in such a young, progressive company does not come along very often. I hope to learn as much as I can, and play my part in the continuing success of the firm.”
