Her 6th grade choir performed for U.S. Congressman Sam Johnson and Texas Representative Scott Sanford and received accolades for superior performance at local festivals.

Ms. Koziatek received her Bachelor of Music and Master of Music degrees in Vocal Performance with related fields in Music Theory and Vocal Pedagogy from the University of North Texas where she later earned her K-12 music certification. Ms. Koziatek holds Kodàly certification in both the traditional and choral track.
