Small family structural design and technical services business, comprising of father (Roy) and son (Conrad). The business was formed in 1994 and operated in the northern suburbs of Adelaide, South Australia, in particular in the Tea Tree Gully (TTG) area and surrounds, until 2014 when we moved everything to Maitland on the Yorke Peninsula. The trading name was solely Roy Harrison & Associates until 2009 when we registered the company name MiScion Pty Ltd: now the name alternates between the two.
