He was born in 1982 to an Israeli family living in Rotterdam, Netherlands. He began playing the trombone at the age of 13 under the guidance of his grandfather, a former trombonist of the Israel Philharmonic Orchestra. He enrolled in studies at the Rotterdam Codarts University, and later was admitted to the Staatskapelle Berlin Akademie and the West-Eastern Divan Orchestra, where he had the opportunity to work under the direction of Daniel Barenboim. He continued his studies with Andreas Klein, Rainer Vogt, and Prof. Stefan Schulz, graduating with a master’s degree from the University of the Arts (UdK) in Berlin in 2013.
Since 2012, Tomer has been serving as the bass trombonist of the Deutsches Symphonie Orchester Berlin. He occasionally performs with orchestras such as the Berliner Philharmoniker, Concertgebouw Orchestra, Gewandhaus Leipzig, Lucerne Festival, Staatskapelle Berlin, Deutsche Oper Berlin, and Boston Symphony.
He is also a member of various brass ensembles, including the International Trombone Ensemble, Berlin Trombone Quarter, and Trombone Unit Hannover, with which he won the first prize at the 2011 Deutsche Musikwettbewerb. Additionally, he is a frequent guest artist with the Berliner Philharmoniker Brass Ensemble and the Lucerne Festival Brass Ensemble.
In addition to music, he is passionate about performance art, dance, and acting, which resulted in the multimedia production “NO-MAD,” with dancer and choreographer Oren Lazovski, premiered in 2016 at Radialsystem in Berlin. In his latest project “Sliding thru the Opera,” Tomer collaborates with another trombonist Lars Karlin and pianist Ohad Ben-Ari. The performance includes operatic hits arranged for trombone, bass trombone, and piano, with the premiere scheduled for the upcoming season at the Berlin Philharmonic.
Since 2023, he has been an artist endorsed by Bach.
