My name is Brittany Semsch; I am a Licensed Professional Counselor (LPC) employed at Tri-County Mental Health Services as the School-Based Clinical Supervisor. I received my bachelor’s degree in Sociology and Psychology at Northwest Missouri State University and my master’s degree in Counseling Psychology at Avila University. I began my career as grief counselor at Solace House where I worked with children and their families in the areas of grief/loss, suicide, and trauma.  I transitioned into a therapist position at an adolescent residential program where I gained experience providing individual, family, and group therapy.  For the last five years, I have worked as a school-based therapist where I provided assessments and treatment for children and adolescents who struggled with mood, behavioral, and relational issues.

My name is Krista Heller; I am a Provisional Licensed Professional Counselor (PLPC), under the direct supervision of Lori Wheelhouse, MA, LPC, LCPC, with Tri-County Mental Health Services.  I completed a dual master’s degree in Mental Health Counseling and Art Therapy Counseling from Emporia State University in May of 2014. Art therapy uses the creative process of making art to improve physical, mental, and emotional well-being.  Participating in art therapy does not require previous art experience or talent.

In addition to providing art therapy services, I supervise the Expressive Therapy
team at Tri-County Mental Health Services.

Rebecca Schroeder
School-Based Resilience Specialist

My name is Rebecca Schroeder; I am a mother of three energetic kiddos and excited to welcome number four in September of 2019. I grew up in Manhattan, Kansas, with my two brothers. Graduating in the class of 2013, I received a Bachelor of Arts degree in Elementary Education and a Bachelor of Arts degree in Special Education from Benedictine College. Following graduation, my career began at Earl M. Lawson Elementary School in Leavenworth, Kansas, where I was a special education teacher for grades kindergarten through 5th grade for six years. During my time at Lawson, I was introduced to the concept of trauma informed care within the classroom setting. This transformed my philosophy of education and ultimately who I am as a wife, mother, and educator. I co-founded the Resilience Team at Lawson Elementary School in the fall of 2016. This program provided monthly trainings to school staff based on trauma informed care and building resilience in the classroom. I found a passion for teaching resilience to students through the educator. In the spring of 2019, I made the tough choice to leave the classroom and begin a journey of building resilient culture as a career. This brought me to the Tri-County family where I have initiated the role of School-Based Resilience Specialist. Within this position, I am able to provide classroom based education to students and training for school faculty as well as provide resilient outlets designed around student need. I am excited to aid in the cultivation of a resilient community within identified Clay County school districts.

Thank you for all that you do for our schools and community!
