Rob Pheasey, Chief Executive, said:
“Marsden Building Society will celebrate its 156 year in 2016. Our results in 2015 continue the trend of growth and financial stability that has built the Society into what it is today.
"It has been another busy and successful year: a year of growth, a year of investment and a year of making the Society stronger. Our strength in the future will be largely dependent on retaining the loyalty of existing members and in building a modern mutual that attracts new members in the future."
