Glenn Wrighton, 63, was found guilty on 1 August of “a grotesque breach of trust”.
The victims were four women, three of whom were elderly and one who had suffered a tragic bereavement, reported the Bradford Telegraph and Argus.
The court had heard Wrighton stole £384,595 over a 16-year period while trading as Yorkshire Financial Clinic Ltd.
Judge David Hatton QC told Wrighton: “People had invested significant sums with you in order to cater for their financial futures and those of their loved ones; futures you wholly destroyed.”
The judge said the consequences for the victims and their families were “devastating, financially and emotionally”.
Wrighton, who lived in a £400,000 house, was said to have protected, enhanced and propped up his own financial security with “systematic and repeated thefts”.
“Each had implicit trust in you which you wholly abused by systematically stealing from them, concealed by elaborate lies,” the judge said.
