Carmen Rathert, M.S. CCC-SLP®

Carmen was honored to receive her first job with the Warrensburg Public School District as Speech-Language Pathologist for the Early Childhood Special Education Program. Carmen worked closely with students, parents, teachers, and therapists over the next six years assessing and treating a variety of speech and language disorders, developing and implementing Individualized Education Plans, and learning how to manage student behaviors. It was here that she developed her passion for working with this population. 

Carmen left the Warrensburg Public Schools in search of part-time employment due to the birth of her first son, Nolan. Carmen accepted a part-time position with Western Missouri Medical Center in Warrensburg, Missouri, as a pediatric outpatient Speech-Language Pathologist.  Carmen immensely enjoyed working one-on-one with pediatric patients and their families and quickly saw the importance and effectiveness of parental involvement within the treatment setting as well as in the home environment.  

In 2012, Carmen and her husband were delighted to find out they were expecting identical twin boys; however, at 20 weeks, they discovered their boys were suffering from Twin-to-Twin Transfusion Syndrome (TTTS). ( Tyson and Carmen lost their son, Luke, due to the disease that April. Carmen was monitored closely at the University of Kansas Hospital and welcomed the birth of their son, Lane, at 32.6 weeks. Lane spent 9 weeks in the neonatal intensive care unit (NICU). Carmen gained a lot of perspective through this experience about pediatric feeding and swallowing and the emotional roller-coaster of having a child in the NICU. Lane received occupation and physical therapy through the Missouri First Steps program from the first 6 months he was home. The family was responsible for following through with Lane's home programming.

Carmen continued at Western Missouri Medial Center for three years before returning to the public school system. In 2014, Carmen and her family moved to her home town of Clinton, Missouri. She became the Speech-Language Pathologist for the Early Childhood Program and served for one year before opening her private practice. 

 Carmen immensely enjoyed working one-on-one with pediatric patients and their families and quickly saw the importance and effectiveness of parental involvement within the treatment setting as well as in the home environment. Carmen has a strong clinical background in early childhood speech and language development which includes phonological processing disorders, articulation, childhood apraxia of speech, receptive language and auditory comprehension and memory, expressive language, and Autism Spectrum Disorders. She enjoys challenging patients and loves working with families. Carmen never stops learning and is always looking for new tools/strategies for her therapy toolbox.

Megan began her career at the Missouri Veterans Home in Warrensburg, MO. In her short time there, she had the opportunity to serve local veterans by ensuring comfortable and safe eating and swallowing.
While she enjoyed working for and interacting with the gentlemen, she found that she longed for a greater variety in her caseload and missed working with children.

Here, Megan has broadened her scope of experience by working with children and adults, and training in videofluoroscopic swallow study. She also gained immense appreciation in working closely with families, speech language pathologists, physical therapists, occupational therapists, and nursing staff. It was also here that Megan first met Carmen, where Carmen recognized her learning style and fostered her clinical skills by encouraging open communication and collaboration in treatment approaches.  

In 2015, Megan was thrilled to join her friend and mentor, Carmen Rathert, as a contract therapist for Carmen’s new practice. Through Chatterbox, Megan is able to provide accessible services within the Warrensburg and Whiteman Air Force Base communities. She is enjoying the opportunity to gain experience in new settings, and is pleased to provide convenient therapy services for the busy lifestyles
of today’s families.

Megan enjoys thinking outside of the box and incorporating learning input strategies she has
learned in collaboration with physical therapists and occupational therapists. Megan feels that it is important to offer learning opportunities through a variety of input channels, including tactile, auditory, and visual experiences.

Megan is anxiously awaiting her fifth year as a Speech-Language Pathologist so that she can begin to pursue her Clinical Specialty Certification in Child Language and Language Disorders. In the meantime, Megan hopes to participate in PROMPT training courses to obtain her PROMPT certification.
