The Society has been expanding its range of competitive products through its intermediary and branch distribution as it looks to grow its business both locally and across England and Wales.
The new role has been created as part of the strategic plan to increase segmented residential and buy-to-let mortgage lending as well as build on The Mansfield's reputation for investment products.
Green has joined from the Earl Shilton Building Society, where she reached the position of business development director in her 15 year career with the Society.
She said: “One of the main factors in my decision to join The Mansfield is the timing. It is a very exciting point in the Society’s history with a challenging and competitive market ahead of us.
“The Society has a good reputation with enthusiastic staff and I’m looking to use and develop the extensive skills I have learnt so that The Mansfield is among the first names that people think of for their financial needs.”
Gev Lynott, chief executive of The Mansfield, added: “We are delighted to welcome Audrey to head up our commercial activity.
“She comes with an impressive track record and I am sure that she will put her experience to good use on the Society’s behalf.
“The financial services landscape is evolving rapidly and with Audrey’s guidance and energy, The Mansfield will continue to embrace change and grow to service the needs of customers here in Nottinghamshire and further afield.”
