She is replacing Scott Kennedy, who has taken up a new role in NatWest’s mortgage telephony business.
Dillin has spent 12 years working with brokers in Essex and East London as a field business development manager, while she has held mortgage positions with RBS Group for 30 years.
She will manage a team of nine field BDMs in the new role.
Paul Kane, acting head of sales, NatWest Intermediary Solutions, said: “I am delighted that Paula has joined my management team.
“She has a wealth of experience and is highly regarded by the brokers that she has been dealing with in her role as a BDM for her drive, knowledge and desire to help. She has particular expertise in the buy-to-let and new build sectors which are two areas of the market that we expect to see significant growth in this year.
“I am sure that the brokers on Paula’s panel will miss her but will equally congratulate her on this well-deserved appointment.”
