Harus Rai has been appointed by Capital Cranfield as head of sole trusteeship.
He started work in the newly created, London-based role on 14 August - joining Capital Cranfield from Capita Asset Services, where he was a professional trustee for over seven years.
Rai will work with Capital Cranfield's client directors to ensure governance standards are maintained, and work closely with the business development team on various initiatives.
The firm's managing director Neil McPherson said Rai's experience and focus will help develop its sole trustee model further.
Rai commented: "My aim is to ensure that Capital Cranfield continues to set the standard in sole trusteeship. As well as leading the development of our proposition, I am looking forward to working with our professional trustees and governance team on both existing clients and new opportunities".
Rai previously worked as a pension benefits researcher at Aon Hewitt for four years, where his main focus was in pension legislation. He was also employed by Mercer for six years, initially working as a pensions administrator, before becoming a consultant in 2001.
The Pensions and Lifetime Savings Association (PLSA) has announced it will shrink its board by more than one-third as part of a governance overhaul to make it "agile and more appropriate".

The advent of collective pension systems could help the UK avoid demographic challenges which will make it "impossible" for society to help savers in retirement, experts say.
