Ashmore joins from broker John Charcol and reports to managing director, Gemma Harle.
As part of the role, Ashmore will help shape Intrinsic’s mortgage and protection proposition.
Intrinsic last year launched a separate mortgage network to give greater focus and support to its advisers.
Ashmore, said: “I’m delighted to be joining the largest mortgage and protection network in the UK.
“Intrinsic has the scale and strength to build a market leading proposition.
“Housing demands have shifted and to meet these demands we need more innovative products such as inter-generational mortgages to help first-time buyers.
“The network is in a prime position to find opportunities like this and develop solutions.”
Harle (pictured) added: “Jackie is an excellent addition to the mortgage network, and brings in depth knowledge and experience.
“Her understanding of the current mortgage products and services out there is invaluable and will help Intrinsic ensure it is developing products and services that meet advisers’ and their clients’ needs.”
