Dr. Katie Forslund is a Clinical Psychologist currently working under the supervision of Licensed Clinical Psychologist, Dr. Nick Bagnell. She has worked with teens, adults, veterans, and LGBT community members experiencing a wide array of challenges and across a variety of settings including community mental health, college counseling, corrections, and hospitals.

uncomfortable, and at times grueling, so humor can be a great tool in easing the anxiety that is likely to arise.

Dr. Forslund has a passion in working with clients having difficulties with depression and anxiety stemming from issues related to life transitions, grief, relationship concerns, poor stress management, and work-life imbalances. She uses an integrated evidence-based approach in addressing these difficulties, which includes mindfulness (self-awareness), emotion regulation,
and interpersonal effectiveness. These approaches build skills for setting and maintaining healthy boundaries and effective communication. She also helps clients to find purpose, value, and meaning in life to help improve self-esteem.

Dr. Forslund’s approach to therapy is to clarify what brings you to therapy and explore how and why that is happening. During this process, themes will be collaboratively drawn out and integrated in order to build an understanding of how you perceive and interact with the world around you. By teaching and practice of evidence-based self-awareness and emotional regulation
techniques, you will be better equipped in managing life stressors. 

Outside of work, she enjoys spending time with her family, reading, and watching stand-up comedy and cringe-worthy reality tv.

Nicole's professional trek commenced in her home state of Ohio, where she embarked on her mission to support individuals facing mental health challenges.

Here, she developed her proficiency in assisting adolescents dealing with issues such as anxiety, depression, Attention Deficit/Hyperactivity Disorder (ADHD), Autism Spectrum Disorders (ASD), and behavioral disorders. 

A pivotal juncture in her career unfolded with her relocation to South Carolina, where she focused her efforts on at-risk children. This change allowed her to further refine her skills and deepen her understanding of the unique needs of this vulnerable population. Nicole's professional journey soon brought her to Springbrook Behavioral Health System which marked another significant chapter. 

At Springbrook, she collaborated closely with fellow specialists in a residential facility dedicated to serving children, adolescents, and young adults on the autism spectrum. This interdisciplinary approach showcased her adaptability and skill in creating a nurturing environment for those under her care and drawing perspectives from other disciplines.

Cliff has experience working as a therapist in juvenile and adult corrections, inner-city high schools, military installations with active-duty personnel, Veterans, and college students. When working with any client, the first session consists of a biopsychosocial assessment, in which a treatment plan for therapy is collaboratively discussed.
