Eunyoung Kim a virtuoso soloist and chamber musician, has performed with numerous organizations in her native Korea, the United States, Japan, and Türkiye. She has been commended for her "coherent interpretation, emotional depth" by pianist David Allen Wehr and "uncanny, virtually unique ability to perform contemporary music" by pianist Victor Rosenbaum, who also describes her as "one of the most sought-after pianists." The Xanthos Ensemble, of which Ms. Kim has been a member between 2006 and 2014, has been praised as "so copiously skilled and confident" by the New York Times and "brilliant" and "stun" by the Boston Globe.

Ms. Kim was awarded a scholarship from the Korean Government, being selected as a top student from the music department at Korea National University of Arts in Seoul, where she received a bachelor's degree in piano performance. After completing such an intense conservatory curriculum at Korea National University of Arts, she continued her study, focusing on the academic field at Boston University, where she got a master's degree in piano performance as well as being selected as a member of the American National Music Honor Society, Pi Kappa Lambda. At Boston University, she met her mentor, pianist Robert Merfeld, who has inspired her, particularly in chamber music, and invited her to Longy School of Music in Cambridge, MA, where she achieved a three-year double major performance diploma with distinction.

Her post-academic achievements include winning prizes in International Chamber Music Ensemble Competitions in 2005 and 2006, third place in Hugo Kauder International Piano Competition in 2008, and Gladys Cauthen Award in International Beethoven Competition in 2009. In addition to premiering many new solo and chamber works in New England, she has performed at the Kendal Music Series in Boston, Tanglewood Music Festival, New Hampshire Music Festival, International Soroptimist Series in Japan, New England Conservatory faculty concerts, and Turkish Arts and Culture Festivals in Boston. Ms. Kim had a successful concert tour in Korea in the fall of 2012, followed by another tour of different universities in Türkiye in both 2013 and 2015. Besides her active performing career, she has served as the music director of the Boston Youth Music Ensemble, a youth performance group, since 2021. In 2023, she and her pianist friend launched Ensemble NowUs, a four-hand group that has performed regularly in a variety of settings.
