Charley Clarke is the longest serving employee and his promotion involves taking over the management of the technical service team as well as running the service desk team.
Fern Ritchie, meanwhile, joined the company as an apprentice.
Lee Hewson, managing director, said the changes demonstrated the company’s commitment to the development of its employees.
He said: “It’s important to us that all our staff have the opportunity to progress.
“We have our own in-house training programme which gives employees the chance to develop their careers.
"That way, we can retain high quality staff and continue to provide excellent customer service.”
The recent changes follow the decision by a founding director of the company, Simon Cox, to retire following a period of ill health.
Simon and Lee established Your IT Department in a small office in Nottingham in 2009.
From that initial partnership, the business now employs 24 staff and has an annual turnover of £2.4m.
Simon said: “I’ve thoroughly enjoyed my time helping to develop Your IT Department into the successful business it is today.
“I’m proud that we’ve created and secured local jobs and helped employees to develop their careers.
“It’s also been great to work closely with a range of long-standing clients and I’m sure they will continue to receive a first class service in the future.
“The decision to retire is not one I’ve made lightly, but it’s the right time to let other people flourish within the company.
"I’m looking forward to spending more time with my wife, Juliet, and enjoying some quality leisure time together.”
