Meet the team
Simon Hayward
Partner
Simon has worked in the insurance industry for over 15 years with the last 12 years at CR International (Cambiaso Risso) and prior that 4 years at Thomas Miller.
At CR he began as a War and K&R Broker and progressed to being Head of Marine of one of the largest Marine Brokers worldwide. He played a key role in building an office of 5 to almost 40 staff by the time of his departure and in doing so exceeded annual budgets regularly. One of Simon’s key achievements was growing a London office which previously was almost entirely reliant on worldwide group production to 40% London production in the space of 7 years.
His previous experience includes many different types of marine tonnage, record and domicile, and this has given him a very high level of experience and working knowledge.
