Jerry Jackson Lee II, 47, of Evans, was convicted June 13 of aggravated sexual battery in Columbia County Superior Court. The jury acquitted him of three counts of child molestation.
Mr. Lee, who has since surrendered his medical license, was arrested in 2005 after police responded to a domestic dispute, prosecutors said.
Augusta Judicial Circuit Chief Judge J. Carlisle Overstreet handed down the maximum sentence, which also requires Mr. Lee to register as a sex offender.
Defense attorney Richard E. Allen asked Judge Overstreet to sentence Mr. Lee to the minimum mandatory sentence of 10 years, but the judge said the defendant posed a threat to the public and the victim's family.
Assistant District Attorney Jeff Johnston said the maximum sentence was fair based on Mr. Lee's actions.
Mr. Lee has been held without bond in the Columbia County Detention Center since his 2005 arrest on a probation violation from Hazelhurst, Ga.
That charge involved a 2004 fraud allegation in which he was accused of acquiring a controlled substance using a revoked registration number.
