Katie is currently Principal Horn of both The Dallas Opera and the Dallas Chamber Symphony, and she also frequently plays as a substitute or extra horn with the Dallas Symphony and Fort Worth Symphony. Prior to becoming Principal Horn for the opera, she was Third Horn from 2014-2017. In addition to performing, Katie also teaches private lessons in the Dallas area. 

Katie graduated with her Master of Music degree from Northwestern University in 2010, where she studied with Gail Williams, the former Associate Principal Horn of the Chicago Symphony. She completed her undergraduate work at Southern Methodist University, studying with Greg Hustis, former Principal Horn of the Dallas Symphony.

In 2013, Katie was a featured soloist with the Dallas Chamber Symphony, where she performed the Serenade for Tenor, Horn, and Strings by Benjamin Britten. Following her performance, Scott Cantrell of the Dallas Morning News said "Katie Wolber did an impressive job with a fearsome horn part composed for the great virtuoso Dennis Brain." Similarly, Jamie Laughlin of the Dallas Observer noted that she "kept the instrument's rich tones in check whether jumping muted octaves or sliding through Britten's warmly dark dissonance." And lastly, Gregory Sullivan Isaacs of Theater Jones said Katie "did a great job with the horn part, a shoal upon which many others have floundered."

When Katie is not teaching or performing, she can be found spending time with her husband, two sons, two rescue dogs, horseback riding, cake decorating, learning Spanish, and reading.
