Jessica O'Sullivan


My name is Jessica O’Sullivan and I am committed to providing a supportive, non-judgmental space to help clients process openly. Each client is unique and their therapeutic needs will vary. Providing meaningful therapeutic interventions while assisting individuals in navigating who they are and how to flourish in the world around them is why I am a therapist. In my clinical work, I will assist in uncovering the meaning behind behaviors and provide guidance to strengthen familial bonds.

I strongly believe in celebrating the uniqueness of each child while guiding them to learn emotion regulation and distress tolerance skills. Through the use of play therapy children will have the opportunity to give voice to their feelings and thought process that they may not be able to express verbally. My therapeutic space will incorporate empathy, acceptance, transparency, humor and respect to promote emotional healing and allow clients to express themselves in a safe environment.

I have experience in working with issues specific to anxiety, depression, mood disorders, substance use, eating disorders, trauma and grief. My experience and training has guided me to utilize a strength based approach paired with multiple treatment modalities including dialectical behavior therapy, cognitive behavior therapy, motivational interviewing and play therapy.

I am currently accepting clients of all ages, both virtually and in person, at our Orland Park location, and I am greatly looking forward to embarking on you and your family’s wellness journey – together.

After earning my Bachelor’s of Science in Child and Family Development from Western Michigan University, I went on to earn my Master’s degree in Social Work from the University of Michigan.  These institutions are the foundation of my understanding of family systems and developmental stages of early adolescence, and it is a foundation I have been building upon throughout my career as a therapist.

Whilst completing my master’s degree, I was awarded as a Caren Kaplan Scholar – denoting my commitment to the general welfare of children and families while focusing on addressing issues of chronic neglect. Since graduating, I have spent four years working as an emergency services clinician for an inner-city inpatient hospital in Chicago, as well as a private residential facility for teens and adolescents coping with complex trauma and dual diagnoses.

All of these experiences have brought me to Mosaic Counseling, where it is my pleasure to provide an inclusive client centered approach to suit each individual’s developmental stage, personality, and psychosocial history.
