Two leading OH practitioners were acknowledged in the 2013 New Year Honours List.
Dr Steve Boorman, an OH consultant and author of the NHS Health and Wellbeing's Boorman review in 2009, was made a CBE.
Boorman, formerly chief medical adviser to the Royal Mail Group, is now medical director for UK OH services at provider Abermed.
He said: "It is humbling to know that I have been recognised, but it's also a testament to the teams I have worked with."
Boorman is a well-known consultant in OH circles and has been published widely in international medical journals. He regularly gives presentations in the UK and around the world on issues regarding health in the workplace.
In other roles, Boorman is an honorary senior clinical lecturer with the Institute of Occupational Medicine at the University of Birmingham, chief examiner to the Faculty of Occupational Medicine's diploma in occupational medicine examination and is a past president of the Royal Society of Medicine's occupational medicine section.
He was joined in this year's honours list by Robert (known as Bob) Crawley, head of health and well-being at the Metropolitan Police Service, who was made an OBE.
Crawley received his award in recognition of his work in providing OH services to Metropolitan Police Service officers and staff for more than 40 years, the past 12 of which have been within its OH unit.
His achievements have included reducing absence levels by 30%, encouraging healthier lifestyles and fitness regimes among employees and offering advice and guidance on issues such as gender-specific cancers, said the service.
