The Dallas Symphony Orchestra has appointed a concertmaster and co-concertmaster to share the leader's chair left vacant since Emanuel Borok retired last August. The two new leaders will join the orchestra for the start of the 2011–12 season.

Kerr, who has held concertmaster positions at the Cincinnati, Charleston and Royal Concertgebouw orchestras, will perform 12 weeks with the Dallas SO during the 2011–12 season and 16 weeks in the following season. This arrangement allows him to stay on as principal guest concertmaster of the Indianapolis Symphony Orchestra, and to carry on teaching at the Indiana University Jacobs School of Music.

Olson, 24, is a graduate of the Cleveland Institute of Music's Concertmaster Academy, where he studied with William Preucil. Currently the concertmaster of the Canton Symphony Orchestra in Ohio, he has served as guest concertmaster of the Toronto, Omaha and Tucson symphonies.
