Early Life and Background
Brett Charles Sullivan was born on February 22, 1994, in Stockton, California. He grew up in the same central California city that produced several other professional baseball players, surrounded by a family that supported athletic pursuits. Sullivan attended Lincoln High School in Stockton, where he played baseball and began attracting the attention of college recruiters.
At Lincoln High School, Sullivan shared the field with his older brother, Tyler, and the two played together on the same team. That family connection helped shape his early competitive drive and gave him an everyday catching partner during his formative teenage years.
Path to Professional Baseball
After completing high school, Sullivan continued his playing career at the University of the Pacific in Stockton, where he suited up for the Pacific Tigers, the school’s college baseball program. He spent several seasons developing his game at the Division I level while facing some of the best amateur competition in the West.
In the summer of 2014, Sullivan joined the Bourne Braves of the Cape Cod Baseball League, one of the most respected collegiate summer circuits in the United States. The experience against elite college talent helped sharpen his skills heading into his final year of college eligibility.
