The Chicago Kwonsa Choir was founded on March 6, 2015, by five friends who attended a prayer meeting together. Inspired by Isaiah 43:21, "The people whom I formed for myself that they might declare my praise," they established the choir to offer praises to God. The purpose of the choir is to offer heartfelt and devoted praise to God, promote cultural and community service through their performances, and foster fellowship and camaraderie among the choir members. The choir exclusively performs hymns that exalt God.

Currently, the choir consists of approximately 40 members. Dr. JinUk Lee, a professor at Chicago Northern Seminary, serves as the conductor, Sarah Yun Mayer serves as pianist and Inok Lee is the team leader. The choir is open to anyone who believes in and serves God, aiming to be a place where members can experience God's presence through abundant grace in their praises, often resulting in tears of confession and testimony.

Founded on the scripture Isaiah 43:21, the Chicago Deaconess Choir has grown since its inception in March 2015. Their mission is to offer heartfelt and sincere praise to God and to engage in cultural community service through their performances. They held their first concert in April 2016 and have performed five annual concerts to date. Rehearsals are held every Saturday from 10:00 AM to 12:30 PM at Yesurun Church. The choir continues to evolve, providing an open platform for believers to join and experience the overwhelming presence of God through powerful and emotional worship. The Chicago Deaconess Choir is diligently preparing for their 6th annual concert, set to take place in September 2023, with a unified and passionate spirit.
