Nichola Bell joins from Vida Homeloans where she was key account manager, and will work with advisers in the north east.
Carly Gibb joins from NatWest where she most recently held the post of business development manager (BDM). She will support brokers in London and East Anglia.
Toni Mason will be responsible for firms in London and the south east, and joins from Together where she was a BDM, while Helen Mason will oversee the Midlands having joined from Legal & General.
The firm said the new team members will help it strengthen relationships with the mortgage brokers it already works with, as well as expanding its reach to support more new intermediaries.
All four will report into Campbell Stanners, who took on the newly created role of advisory relationships director at Bankhall and PMS in May.
Stanner said: “ All of our new account managers have an in-depth understanding of the advisory market and a proven track record in business support. They’re an excellent addition to the strong team we already have in place at PMS and which we will be investing in further over the coming years.”
