Core 307 Physical Therapy, LLC was established in April 2018 with motive to provide Gillette, Campbell County, and the surrounding areas with quality, patient-centered physical therapy rehabilitation.  We believe that physical therapy should be centered towards YOU, YOUR goals, and to improve YOUR quality of life. 

​​Core 307 provides a professional, intimate, and humble atmosphere; we believe you are more that a patient, you are our friend.  We intentionally maintain a small staff in order to provide consistency and build rapport with our patients.  Core 307 PT believes patient education is empowerment and vital to your success following injury and your overall wellness. 

Although we are the "new kid in town," Brittany has been practicing in Gillette for six years and has worked in the physical therapy field for 11 years.  It is with her experience as a prior physical therapy patient, physical therapy tech, student physical therapist, and now Doctor of Physical Therapy that provides her with a broad set of treatment skills, evaluation techniques, educational foundations, and passion for the profession.  

Brittany was born and raised in Gillette, and is excited to use her knowledge and skill to rehabilitate the people of Gillette.  She has practiced in Gillette the last eight years and recognizes the uniqueness of injury related to the jobs and recreation in Northeastern Wyoming.
