Obituary of Andrew J Kosiba

Andrew J. Kosiba, age 38, of Danielson, CT passed away unexpectedly Wednesday, April 22, 2026 at his home in Danielson, CT. Born in Worcester, MA and raised in Dudley, MA, Andrew was the son of the late John Kosiba and Kathleen (Peterson) Kosiba. Andrew graduated from Shepherd Hill Regional High School in 2006 and later earned a degree in Jazz Studies from Western Connecticut State University in 2010. A pianist since the age of 7, he dedicated his life to mastering the instrument. Andrew shared that passion with others through music education, aiding many students in pursuing their own musical dreams. Over the last 20 years, Andrew collaborated and played with musicians across Connecticut, New York, and Massachusetts in multiple ensembles, bands, and projects. Through hard work and creativity, he recorded and was featured on 13 albums and toured all across the Eastern US. He was one of the first members of the New Haven Jazz Underground, a guild of musicians dedicated to performing and producing concerts in the Greater New Haven area. Andrew often accompanied special guests and jazz luminaries through his work with the Underground. More locally, Andrew was the Music Director and Organist at Sturbridge Federated Church for 15 years. Under his direction, the Music Ministry used their musical talents to praise God weekly at church services. The Ministry also performed in the community, including holiday performances at Old Sturbridge Village, and participated in ecumenical community choral workshops. Andrew was always eager to bring in small groups and solo musicians to church services throughout the year to do God’s good work through voice and instrumentation. Andrew’s professional commitment to youth music education began 15 years ago and included various roles including Private Lessons Instructor, Jazz Clinician, Classroom General Music Teacher, Choral Director, Band Director, Jazz Band Director, and Pep Band Director, in the communities of Shrewsbury, Framingham, Uxbridge, Dudley-Charlton, and his most recent employment at Sutton Middle School. Andrew had turned his interest towards working in Special Education where he hoped to spend his future. In his free time, Andy could be found boating with family on Quaddick Lake, playing a round of golf with his late father, listening to vinyl records on his favorite sound systems, or going for a drive to find and enjoy himself a solid cup of coffee. He is survived by his mother Kathleen (Peterson) Kosiba of Woodstock CT; Uncle James and his wife Marylee Kosiba of Dudley, MA; Aunt Kathie and her husband Bernie Faucher of North Grosvenordale, CT; and his life long friends Nick Di Maria of New Haven, CT and Dave Macuga of Storrs Mansfield, CT. Andrew will also be missed by numerous cousins, countless friends and colleagues, his Pastor David Cote, and his beloved Church family at Sturbridge Federated Church. A celebration of life will be held 10:00 am on Saturday, May 16 at Sturbridge Federated Church, 8 Maple St., Sturbridge, MA with Pastor David Cote officiating. Burial will follow in Oakridge Cemetery in Southbridge. Calling hour at the church will be Saturday, May 16 from 9:00AM to 10:00 AM.
