USBands Adds Dynamic New Team Members

In preparation for the upcoming 2021 fall marching band season, along with a commitment to organizational excellence, improved customer experiences for educators and adjudicators, and expanding the reach of USBands to new and diverse audiences, USBands is profoundly excited to welcome four new members to the team in full-time and advisory roles. 

Hall of Fame instructor/designer, adjudicator, psychotherapist, and author Shirley Dorritie of Knightsen, CA joins the team as the first Director of Adjudication Philosophy for USBands. In this newly created role, she will be responsible for developing and implementing the adjudication philosophy and processes across USBands marching band, concert band, and jazz activities.  Shirley's main focus will be on elevating the ensemble’s overall experience by improving existing adjudication processes, clarifying standards, and providing education to both directors and adjudicators. 

After two years of working with the Big Brothers & Big Sisters organization,  Eric James of Allentown, PA returns to USBands as the Director of Event Operations, a role which he held from 2016-2019. Eric’s responsibilities will be wide-ranging with a concentration on establishing and maintaining a culture of organizational excellence throughout the annual schedule of events serving marching bands, the indoor activity, and future expansion in the concert and jazz genres.

Joining the team after more than 20 years as a music educator, David Marshall of Bristol, RI brings a wealth of practical experience and knowledge to join the USBands team in an Ensemble Relations role. David will serve as the main point of contact for music educators to USBands to serve their needs, answer their questions and provide access to educational and performance opportunities for student-performers throughout the nation. 

Errick Prince of San Antonio, TX has joined the USBands team as a Coordinator in developing a new series of Traditional Show-style band competitions in the Southeast and Texas regions, with two exciting events to debut in the fall of 2021. Errick’s extensive background in the marching arts as a performer, educator, and currently as the Fine Arts Department Chair at McCollum High School and Music Professor at Randolph/Lackland Air Force bases, will allow for USBands to broaden its commitment to the diversity of performers and program at events created specifically for the Traditional Show-style band community.
