Felicia Kellen, MS, LMFT
Residential Treatment Supervisor

I received a Master of Science in Psychology with a specialization in Child and Adolescent Development from Capella University. I am a Licensed Marriage and Family Therapist.

I have worked at a variety of levels within the mental health field. I started as a Mental Health Behavioral Aide and a Mental Health Practitioner before the Leo A. Hoffmann Center as a residential therapist. I joined Hoffmann Counseling Services as an outpatient therapist in 2019. I now direct outpatient rehabilitative services.

I have experience treating a variety of concerns for all ages including anxiety, depression, transition to adulthood, with areas of focus including birth through age 5, trauma, parenting and family therapy, and problem behaviors related to sex and sexuality.

I am trained in Child Parent Psychotherapy (CPP), have fully completed training in Trauma Focused Cognitive Behavioral Therapy (TF-CBT), Eye Movement Desensitization and Reprocessing (EMDR) and DC 0-5, with additional training to provide yoga and mindfulness based approaches and Polyvagal theory.

I believe creating a positive therapeutic relationship with the people I work with is done best by providing a relaxed, open, and non-judgmental environment. I make an effort to approach each new relationship with a sensitivity, open-ness, and respect of each persons’ unique experience. I enjoy using holistic approaches that are supported by modern research and working collaboratively with each individual to help reach your ultimate goal.
I live outside of the Mankato area with my family and dog. I enjoy spending my time outside, with family, and absorbing new knowledge. I particularly enjoy watching my child explore around at the park as she learns about the wonders of the world.
