A clinical psychologist from Minnesota has been arrested for allegedly carrying on a sexual relationship with a vulnerable male patient, whom she had falsely accused of sexually assaulting her.

Johanna Lee Lamm, 43, was arrested on October 11 on a felony charge of criminal sexual conduct by a psychotherapist during a session.

If convicted, Lamm could face up to 15 years in prison and a $30,000 fine.

According to a criminal complaint cited by the Minneapolis Star Tribune, the case against the therapist began unfolding in August, when Lamm called police accusing her male patient of raping her at her Minnetonka office.

Lamm, who according to her social media account is married to an attorney, warned investigators that her patient would tell them they were having an affair.

When police interviewed Lamm's patient, described in court records as a 'vulnerable adult,' the man told them he and his therapist had a consensual sexual relationship that lasted four months, with the encounters taking place during his appointment for which Lamm charged him $200 each.

‘Victim stated that sexual contact at appointments began with DEFENDANT’s suggestion of mutual masturbation and eventually led to sexual intercourse,’ police claimed.

The man showed police text messages and voicemails from Lamm, according to the complaint.

Lamm's patient, who has been diagnosed as bipolar and possibly schizophrenic, told police he and Lamm had a consensual sexual relationship that lasted four months

When police reviewed the contents of the therapist's phone, they found that she had deleted most of the texts from her patient.

When faced with the evidence, Lamm allegedly admitted to having a consensual affair and that her patient never raped her.

Lamm's alleged sexual trysts with the patient took place during his apportionments, for which she charged him $200 per sesison

Billing records indicate that Lamm had been treating the man since May 2015. A search warrant affidavit revealed the man has been diagnosed as bipolar, possibly schizophrenic and has been suicidal.

Lamm was released on Monday after posting $100,000 bond, and made her initial court appearance the next day.

Under the conditions of her release, Lamm is not allowed to contact the victim, or come near his home.

She is due back in court on November 13.

According to the Minnesota Board of Psychology’s online database, Lamm has an active license that expires in March 2021.

Lamm's personal website states that she graduated from Hamline University with a double major in psychology and criminal justice. She then went on to earn her PhD in clinical psychology from the Minnesota School of Professional Psychology.

‘Each individual has an important story to tell, and, as an empathetic, genuine therapist, I listen with compassion and offer my observations, insights, or simply my reflective silence,’ she wrote on her site. ‘My approach is non-judgmental and incorporates Eastern philosophy and modern Western psychology and medicine.’
