The method

A functional-movement system, not a quick crack

Most chiropractors treat where it hurts. Dr. Britt's four certifications work as one system to find why it hurts, and those are rarely the same place.

01FMS

Screen

The Functional Movement Screen catches injury risk in healthy patients and athletes before pain ever shows up.

02SFMA

Assess

For patients already in pain, the Selective Functional Movement Assessment maps where movement is breaking down and feeding the symptom.

03FAKTR

Treat

Hands-on soft-tissue work performed while you actively move. Active rehab, not passive treatment on a table.

04RockTape

Support

Kinesiology taping that supports performance, manages injury, and carries the work forward between visits.

Care under one roof

Meet Dr. Britt
"Most chiropractors treat where it hurts. I want to know why it hurts, and then fix that."

Dr. Brittany Seeley founded Twin Tiers in March 2020 to practice a different way: whole-patient, in motion, root-cause first. She graduated from Sherman College of Chiropractic in 2016, and her combination of certifications is uncommon in the Southern Tier.
