Mary began working in insolvency for a national accountancy practice in Glasgow thirty years ago and worked in most divisions of the insolvency department.

She then moved to a smaller firm so she could advance her knowledge on a more hands on basis. She moved back to Leeds in 1987 and commenced working with a small firm of accountants and subsequently made partner.

She left in 1999 to set up her own practice, McCann Taylor.
McCann Taylor became involved with the consumer market both in England and Scotland.

Mary sold McCann Taylor in March 2007 and formed Walsh Taylor to concentrate on helping businesses experiencing financial difficulties.
