"I opened my business after 3 years of working at the typical 'PT mill' with juggling 3 to 5 patients an hour.  So my clinic is now based on NOT being the typical and the first step is spending time with each patient.  So I chose to offer one on one, hour long appointments to address reaching the goals of each individual.  This allows me to learn about the body on each visit in a continuous assessment and treatment progressive approach.  With the home release program and awareness training, I teach patients to empower themselves to improve."
