Company Secretary

Mr Brian Rogerson

Contact 07801 862792


Brian is married to Lizzie and has a son Philip (26) who after spending a year in Australia now works in the farming industry in Cumbria

Brian joined Hexham Auction Mart from school in 1972 and worked in the office for four years before graduating on to selling at farm sales and the annual may term furniture sale at Bellingham. That experience must have put him in good stead as he now runs highly popular and successful quarterly sales at Rothbury selling a mixture of antiques and collectables to a large and varied clientele who travel from far and wide to attend.

Brian counts himself privileged to have sold every category of livestock at Hexham over the years. As well as store sheep regularly through the season, where the change to selling on a Friday has developed the store lamb sale into one of the most prominent in the North, he sells store cattle and sucklers, cull ewes, prime sheep on occasions and has also sold the prime cattle and cull cows. In the autumn Brian sells breeding ewes and gimmers and most breeds of ram throughout the season as well as having sold for a number of years at Kelso Ram Sales.

Apart from all the above and the varied day to day interest that the job gives, Brian was made Company Secretary in 1993 and his many duties involve keeping the company records and minutes, shareholders details etc.

Brian enjoys walking in his spare time and in 2004 walked the entire 84 miles of Hadrians Wall in 3 days raising over £6500 for cancer research.
