    I’ve worked in the MultiValue industry for over 30 years, during that time I’ve covered many roles from developer to consultant. I joined Vmark / Ardent in the UK back in 1997 as a consultant, I moved into Technical Support around 2004. I took over the role of UniData ATS in 2012 and as I’m still UK-based my working day is time shifted in order to cover all the geos we cover around the world. Outside of work I’m married (silver wedding anniversary this year), have 3 grown up children and I’m a senior county football (soccer) referee and like many at Rocket I’m a bit of a musician as I play the drums.
