Inertia Physio & Pelvic Health

  Inertia is the force by which an object in motion stays in motion and an object at rest stays at rest.  

  Inertia Physio and Pelvic health was founded in 2021 driven by the belief that we feel better, smile more, and think straighter when we keep moving.

  While movement goals are different for everyone, we could all benefit from a teammate to help us achieve our desired result. 

  Whether pain, immobility, weakness, or fear is your limitation, Inertia believes that with education, individualized care, and commitment to the plan we can work together to successfully achieve a lasting benefit for you.  

  Let Inertia Physio be your teammate in movement for life!


Our Staff


Bess Mathisen, DPT

Founder/ Director 

A Maryland native, Bess fell in love with this region through service with the Appalachian Service Project.

After receiving her Doctorate in Physical Therapy from Saint Louis University, Bess relocated to Norton, Virginia in 2012.  She treated a wide variety of orthopedic and neurological diagnoses in the outpatient setting before extensive training with the Herman & Wallace Pelvic Rehabilitation Institute.  In 2018, Bess started the first pelvic health rehab program in the region. 

Through three of her own pregnancies and postpartum recoveries, Bess developed a passion for pelvic floor therapy and promoting awareness and education around pelvic health concerns across the lifespan.  

In 2021, Bess founded Inertia Physio and Pelvic Health with the goal of treating the whole patient and not just the diagnosis they come in with, while utilizing the most current tools and techniques available.  An active member of the Virginia Chapter of the APTA and Academy of Pelvic Health, Bess works to stay up to date with the most recent research and evidence in the field. 

Beyond her therapy practice, Bess is a committed Catholic, competitive runner, cyclist, and rock climber. But most importantly she does her best to be a loving wife, mother, and friend.

Robin completed her Doctorate of Physical Therapy at South College in 2023. An Eastern TN native, Robin rowed competitively at Auburn University and now calls Bristol home.
