Emma Thomas takes over the reins as head of communication and brand for the division, replacing Lee Smith, who left earlier in the year.
The group has taken over eight months to fill the role, which reports to director of marketing and strategy Tony Crawford.
In the post, Thomas heads a seven-strong team, covering internal and external communications, alongside brand development and Birmingham Midshires' community involvement programme.
'The initial priorities are to look at the strategic development,' said Thomas.
'An area of growth is internal communications and there are plans to do a lot on that side.'
Part of the brief is also to take charge of Birmingham Midshires' in-house publication Fuseline, produced for the group's staff base of over 2,000.
Thomas boasts a background in internal communications, most recently including a four-year stint at HSBC as internal communications manager, based in Birmingham.
She left HSBC in June and has not been replaced.
Prior to HSBC, Thomas worked for two years as head of internal communications at Waterford Wedgwood, based in Stoke-on-Trent.
She also worked as part of the Lloyds TSB internal communications team during the TSB and Lloyds Bank merger.
At Birmingham Midshires, Thomas said PR will continue to support the group's business strategy.
'Over recent years, the group has moved their strategic direction to look after specialist lending and build on its savings and investment work,' she said. 'PR has played a big part in helping in these areas.
