A former physician assistant has been sentenced to more than 15 years in prison for sexually abusing patients at the Leavenworth veterans hospital.

Mark E. Wisner, 66, Horton, was sentenced Friday in Leavenworth County District Court for one felony count of aggravated criminal sodomy, one felony count of aggravated sexual battery and three misdemeanor charges of sexual battery. The crimes occurred between 2012 and 2014 while Wisner was working at the Eisenhower VA Medical Center.

A jury convicted Wisner of the charges in August.

In court Friday, District Judge Gunnar Sundby denied a motion for a new trial in the case.

The judge also denied a defense motion that sought a more lenient sentence than the one called for under the state’s sentencing guidelines.

Sundby sentenced Wisner to 155 months for the aggravated criminal sodomy charge and 32 months for the aggravated sexual battery charge.

Sundby said he believed these felony sentences should run consecutive because of the circumstances of the offenses.

The judge sentenced Wisner to a year in jail for each of the misdemeanor charges. But Sundby ordered that these sentences run concurrent with Wisner’s prison term.

Sundby said he saw no valid reason for bringing Wisner back to the Leavenworth County Jail to serve time for the misdemeanor charges after he has served a lengthy prison sentence.

This means Wisner was sentenced to a total of 15 years and seven months in prison.

One victim spoke during Friday’s hearing. And written statements from two other victims who were not present were read during the hearing.

The victim who spoke in court said Wisner had been a mentor and father figure to him.

“You gained my trust,” said the victim, who is an Army veteran.

He accused Wisner of overmedicating him.

“I felt safer in Iraq than I did with you after I found out what happened,” the victim said.

Assistant County Attorney Michael Jones said a fourth victim was in the courtroom Friday but did not wish to speak.

John Bryant, Wisner’s attorney, said his client had lost control.

“Whatever control he had, he lost,” Bryant said. “We don’t know the reason why.”

Bryant said Wisner would not be speaking during the sentencing hearing because of pending legal issues.

Multiple lawsuits concerning Wisner’s conduct while working at the VA hospital have been filed in federal court.

In a statement released following the sentencing, County Attorney Todd Thompson called Wisner’s crimes horrific. The county attorney said all of the victims who testified during the trial “served our country heroically, and they deserved the best care, not victimization.”
