Finally, brothers and sisters, whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable—if anything is excellent or praiseworthy—think about such things.

She has experience in 3rd, 4th and 5th grade as well as being a math specialist, TX teacher trainer, family math, curriculum specialist, and 9 years in NISD as a vice principal.
