During his tenure the orchestra has enjoyed tremendous growth, expanding its offerings and increasing its repertoire, including an annual Mahler celebration and highly successful operatic performances each season. The SDSO has received the coveted ASCAP Award for Adventurous Programming for the past three seasons in a row, largely due to its series of concerts featuring works of Pulitzer Prize-winning composers. This program was heralded by the Wall Street Journal as, "an unprecedented programming innovation." Thus far, Pulitzer prize-winning composers Paul Moravec and Steven Stucky have had residencies with the SDSO.
 
Beginning with the 2007-08 season Mr. Gier has been conductor for the complete series of the New York Philharmonic's Young People's Concerts, the first conductor to do so in over 50 years. These highly innovative programs continue to be the vanguard in introducing new audiences to classical music. During the present season Mr. Gier will also make his debut with the Phoenix Symphony and the American Composers Orchestra.

The release of his recording of Symphony No. 2 (42) by American composer Carson Kievman with the Polish National Radio Symphony on the New Albion label received acclaim from many quarters. “The kind of performance composers live for” was the Denver Post’s response, while Spoleto Today wrote, “It provides one of the most powerful musical experiences I have had in recent times.” The SDSO will premiere a new work of Mr. Kievman's in November 2008.

As a Fulbright Scholar (1988–90) Gier led critically acclaimed performances with many orchestras of Eastern Europe. He was invited to the former Czechoslovakia to conduct Dvorak’s Eighth Symphony in celebration of the 100th anniversary of its premiere. Gier took this opportunity to introduce Eastern European audiences to many American masterworks, such as Barber’s Violin Concerto with the Presidential Symphony of Ankara, and Copland’s Appalachian Spring with the Bucharest Philharmonic. “He possesses an innate sense of expression which stems naturally from an absolute artistic sincerity . . .” was how Mircea Cristescu, the Bucharest Philharmonic’s laureate conductor, characterized Gier’s direction.

Gier earned a Master of Music degree in conducting from The University of Michigan under Gustav Meier. “He communicates a true and convincing interpretation to the audience” Meier observed, ”. . . and, above all, he brings the composer to the center of the stage.” As a student at Tanglewood and Aspen he studied also with Leonard Bernstein, Kurt Masur, Erich Leinsdorf, and Seiji Ozawa, and was later invited by Riccardo Muti to spend a year as an apprentice at the Philadelphia Orchestra. At the invitation of the American Symphony Orchestra League he participated in their National Conductor Preview, a highly selective showcase for young conductors.

Mr. Gier has also been in demand as a teacher and conductor in many highly regarded music schools. serving as visiting professor at the Yale School of Music, the College-Conservatory of Music in Cincinnati, the San Francisco Conservatory and SUNY Stony Brook.
