Mairi has specialised in pensions since qualifying as a lawyer in 2005.

Following seven years with DWF’s pensions team, she spent nine years at Pinsent Masons LLP, latterly as a Legal Director, where she provided both pensions legal advice and professional trustee services. She subsequently joined Brodies as a Pensions Legal Director and most recently worked at Burges Salmon in Edinburgh as a Pensions Professional Support Lawyer.

Mairi has extensive experience advising trustees and employers on a broad range of pensions matters, including corporate transactions, scheme governance, funding negotiations and endgame planning. Alongside her advisory work, she acted as a professional trustee for a number of defined benefit pension schemes and developed specialist expertise in public sector pensions, including public sector outsourcing, bulk transfers and TUPE-related pension matters.

Based in Glasgow, Mairi has extensive experience advising trustees and employers on a broad range of pensions matters, including corporate transactions, scheme governance, funding negotiations and endgame planning. Recognised by Legal 500 UK 2022 as a “Next Generation Partner”, she has also been described by Chambers as “straightforward to deal with, gets to the point and understands the issues quickly”. Mairi is also a qualified Mental Health First Aider.

Mairi is fully accredited by the Association of Professional Pension Trustees and also holds the Pensions Management Institute’s Retirement Provision Certificate.
