His solo and chamber music appearances have taken him to such diverse locations as Sapporo, Japan, Sao Paulo, Brazil, and to the Casals Festival in Puerto Rico, the Sarasota Music Festival in Florida, and numerous concert series throughout the United States and abroad. He has performed in the Philadelphia Orchestra's Chamber Music Series with pianists Wolfgang Sawallisch and Yefim Bronfman and at the Saratoga Chamber Music Festival in New York with mezzo-soprano Frederica von Stade and pianist Jean-Yves Thibaudet.

He holds a Bachelor of Music and Performer's Certificate from Indiana University where he was a student of Janos Starker.

At Cornell, Mr. Haines-Eitzen teaches applied cello performance and coaches chamber music. His teaching focuses on an ergonomic approach to cello playing centered on breathing control, relaxation techniques, and motion analysis as they relate to musical expression. As a musical coach, he strives to enhance students' interpretive skills through the understanding of form and stylistic performance practice.
