Katelin Tucker

Katelin Tucker
– PT, DPT, Cert. MDT


Katelin graduated with her Doctorate of Physical Therapy in 2012 from the University of North Dakota. In 2016, she earned her certification in Mechanical Diagnosis and Therapy (MDT), aka the McKenzie Method. MDT is one of the most commonly used treatment approaches around the world. Katelin believes this method is reliable and well-researched assessment for all musculoskeletal issues (back, neck, extremities as well as related issues). It is an exercise-based treatment approach that focuses on specific exercises for what the patient is demonstrating. She has seen significant improvement in outcomes with patients since she began using the MDT approach.

Katelin was born and raised in Minneapolis, MN and spent 6 years in North Dakota attending grad school. Katelin began working at an outpatient clinic in Minneapolis for a large healthcare system before moving to Wyoming in 2017. She has treated all types of patients, with a focus on spinal injuries and rehabilitating athletes.

Outside of the clinic, she enjoys spending time with her husband and their three dogs. She also enjoys traveling and outdoor activities.
