Mahesh Patwardhan was sentenced at Woolwich Crown Court for four counts of sexual assault between July 31, 2008 and September 24, 2012.
Judge Alice Robinson told the court in south London that the impact statement from one of his victims was "one of the most harrowing I've ever read".
"You knew about the serious sexual abuse she suffered as a child," she told the 53-year-old medic, who was in court with his anaesthetist wife, son and daughter.
Patwardhan was also convicted of two counts of fraud relating to falsely billing private medical insurers for work he did not perform.

One of his victims had attempted suicide and said Patwardhan ruined her life, Judge Robinson told the court.
The assaults took place at Queen Elizabeth Hospital in Woolwich and Blackheath Hospital in Lewisham, south-east London, between 2008 and 2012.
The day before one complainant was due to have a hysterectomy, Patwardhan conducted a breast exam, despite the patient telling him she had recently had a mammogram.
During his trial, the jury was told he even asked one woman to reveal her tattooed bottom.
