Hello Tommy,
I myself am a licensed PTA, so naturally I feel inclined towards this kind of content. As you are aware, a huge part of my job requires implementing the PT's plan of care and progressing as appropriate, so little of your payroll would be wasted on frantic googling :) as I am acutely attuned to exercise physiology.
As a content writer, per my portfolio, I've ghostwritten more than 600, yes, 600 pieces of content.
Perfect fit much?
Hope to talk soon,
Nik
