Peter Charles Brennan, 63, was found guilty by a jury in March of 16 counts of indecent assault and two counts of rape.

During the trial the County Court in Ballarat heard Brennan touched 10 women on the breast and vagina during massages at Serenity and Tranquility Health Care and Day Spa between November 2006 and August 2007.

One of his victims, a pregnant woman, feared for the safety of her unborn child as a result of Brennan's actions, the court heard.

"I felt part of me was stolen that day," she said in a victim impact statement.

Brennan also massaged a victim's chest, saying it was helpful for treatment of her asthma.

In sentencing, Judge Les Ross said given Brennan's offending over the 10-month period, it was only appropriate he be punished with a significant jail term.

He said the victims suffered relationship issues, nightmares and social difficulties.

"It is beyond question that in various ways your conduct adversely affected the lives of your victims," he said.

Judge Ross ordered Brennan serve seven years before being eligible for parole.

Outside court, victims were visibly emotional and relieved to have closure.

One woman said she felt the sentence was reasonable and "justice has been served".

The woman said she knew of at least four other women who had not reported their experiences, but believed it was important to speak out because "he did the wrong thing".

"I wished they (other victims) had come forward, but perhaps they are in denial," she said.

Another woman said she felt sorry for everyone Brennan had assaulted.

"I was shocked, hearing it read out again, that he used the same tactics (on other victims), the same stories ... that he thought it was alright," she said.

"It gives me closure."

In a statement, Brennan's former employer Jennifer Forbes said she had been impacted in many ways by what happened.

"I feel abused and conned and angry at myself that I did not see him for what he was," she said.

"Because of this, it's over for them, but it's not over for me."
