Annie Kell, LCSW

lead therapist, Licensed clinical social worker

Annie works with children and families experiencing a wide variety of difficulties such as emotional regulation, social and emotional issues, low self esteem, ADHD, anxiety, depression, trauma, and attachment issues.


Rooted in psychological research of child brain development, Annie uses clinical play therapy to strengthen the connection between brain and body, helping children learn to regulate their bodies and emotions while engaging their interest and enjoyment.


Annie received her Masters in Social Work from Dominican University after graduating from Columbia College Chicago with a BA in Cultural Studies. Most recently, she earned a graduate certificate in Animal and Human Health from Denver University, allowing her to practice animal assisted therapy. Annie’s work is also informed by her years of experience working with survivors of domestic violence and families in the child welfare system.


When not practicing therapy, she loves to spend time with her son, husband, and their pets. Annie enjoys training her dog, Zelda, to become a certified therapy dog. She also likes to make natural dyes and hand drums. Annie is a trained dancer and enjoys spending time hiking in the local forest preserves.

Gretchen will continue to guide the unique focus of Birch Forest as a therapy center that integrates trauma-informed mental health strategies and a cutting-edge neuroscientific lens with natural child development and family focused, relationship-based care.


Gretchen holds a degree in Biology with a minor in psychology from Concordia University Chicago. She has attended trainings workshops through the ATTACh Conference, Trauma and Attachment Symposium, and Meeting the Needs of the Whole Child Symposium as well as completing several courses on topics of the DIR/Floortime Model, parent coaching, and a variety of approaches in trauma informed care with the pediatric population.

Shannon O'Brien, LSW

LICENSED social worker

Shannon received her Masters in Social Work from the University of St. Francis with a specialization in Advanced Generalist Practice. She earned her Bachelor’s degree in Social Work from St. Francis as well, graduating Summa Cum Laude, with a minor in Criminal & Social Justice. While there, she was inducted into the Phi Alpha Social Work Honor Society as well as Alpha Phi Sigma Criminal Justice Honor Society. Shannon sees learning as a continual process and brings her passion for learning to the work she does with every client.


Shannon also has extensive experience supporting children and families in a variety of challenging circumstances. Prior to joining the Birch Forest team, Shannon provided advocacy and support to children and families through the Will County Children’s Advocacy Center. As part of a multidisciplinary team of therapists and law enforcement officials, Shannon helped the survivors of severe abuse share their story and work towards healing and recovery. Drawing from these and other experiences, Shannon recognizes the importance of meaningful support and treatment for those recovering from a wide range of traumatic events.


When working therapeutically with children and adolescents, it is essential to build trust and demonstrate a genuine care for each client as an individual while also helping caregivers to support the healing and change as well. Shannon recognizes that when working through challenges it is important to be proactive instead of simply reactive. Her strengths-based approach to therapy allows children to develop their existing skills and abilities so that they can pursue their goals in therapy confidently.


Outside of work, Shannon enjoys making jewelry and can be regularly found selling her work at local festivals and events with her mother and business partner. She practices mindfulness in nature making meditative art and playing with her two dogs, Ellie & Lilo.
