September 6, 1964 ~ February 16, 2025

Timothy “Tim” J. Alberstein, 60, Sioux Falls, SD, died Sunday, February 16, 2025, at his home.

Services will be held in Visalia at a later date.

Tim left us too soon. Tim grew up in Visalia, CA, the middle child to the blended Alberstein-Mathis family. He attended Mount Whitney High School where he ran cross country and was a member of Sea Scouts. He attended Menlo College in Atherton, CA. His creative and analytical mind fed his ability to work in the telecommunications industry.

Tim was a leader at AA where he mentored others. A lifelong Trekkie and Spock fan, Tim had a dry sense of humor, a warm smile, and a keen wit. His proudest achievement was being a father. Tim was a friend to many, beloved brother, son, and boyfriend to Jessica Duna.

Tim is survived by his children, Rob, Scott, and Ainsley; mother, Susan Alberstein; siblings, Laurie (Brad) Mathis Martin, Greg (Sheri) Mathis, Terry Alberstein, and Christa (Richard) Alberstein Smith; and extended family.

Tim is preceded in death by his father, Jay Alberstein; and grandparents.
