Meet our team of mental health providers

Mental health providers: here to help you

Whether you are scheduling your first appointment or are a returning patient, our caring and expert team will be in your corner. 

Everyone you interact with on our team – including our psychologists, therapists, licensed chemical dependency counselors and administrative staff – will see you and treat you as an individual and a whole person, not just a condition or diagnosis. 

Our mental health and addiction providers do not take a one-size-fits all approach to your care. Whether you are seeking individual or marriage and family therapy, or participating in one of our specialized programs, they are committed to offering you individualized and integrated treatments to best meet your specific needs and goals.

Our ASC Psychological Services experts

Our experts are here to serve you, offering individual and marriage and family therapy at our Mankato and Roseville-based psychology clinics. They see patients in-the-office for visits or can meet with you via teletherapy. 

Our team has deep expertise in helping people through trauma and grief. They also offer specialized programming for veterans and individuals facing addiction and the underlying mental health conditions that go with them. And they provide services to professionals ranging from social workers to lawyers in the form evaluations and assessments, and forensic evaluations and testimony.
