Mike VicaryDirector

Mike Vicary is one of the founders of ORH, with over 30 years’ experience in public sector consultancy and particularly emergency service planning. Now a Director of the company, Mike’s current role involves managing larger ORH projects and keeping abreast of worldwide developments in this fast-moving field. He also performs a valuable quality assurance function across the company.

Mike’s academic background in mathematics and operational research led naturally to a consultancy career in analysis and modelling. Since establishing ORH in 1986, he has carried out more than 300 separate resource planning and modelling studies for a range of organisations across the UK and in Hong Kong, Singapore, Australia, New Zealand and the Gulf states. He continues to play an active part in ORH’s work and enjoys working directly with clients to ensure that their needs are met. Mike is also involved in the development and implementation of ORH’s Dynamic Cover Tool.

In his spare time, Mike likes cooking curries and chutneys, swimming and walking – though he increasingly favours towpaths over challenging coastal ones.
