Our Members


Martin Hammond


Martin is the chairperson and is managing director of Hammond Trotter solicitors.


Having worked in other road traffic firms, Martin decided in 2007 that it was time that he stopped defending clients other peoples way and set up Hammond Trotter solicitors with Philip Trotter.


Since that day, Martin has not looked back, defending clients facing the loss of their driving licences and all that it entails.


Working with the two guiding principles, that initial advice should always be free and that going to trial is not always the best defence, Hammond Trotter Solicitors have become one of the leading road traffic law firms and continue to achieve the results expected of solicitors at this level.


In his personal life, Martin is a committed family man and spends his spare time between his unwavering support for Blackburn Rovers Football Club, and his passion for cars and motorcycles. He can often be found on Britain's roads in his pride and joy, his 1957 Porsche 356 Speedster (obeying the rules of the road of course).
