Jean-Andre Sampieri

Owner & Lead Apple Certified Mac Technician

Tampa, Florida

About

Jean-Andre Sampieri is the owner and lead technician of WarriorMac LLC, a Tampa-based Apple repair service specializing in component-level Mac repair. With 25 years of hands-on experience repairing Apple computers and 4 active Apple certifications, he has built WarriorMac into one of the most trusted names in Mac repair.

Jean-Andre\'s approach to repair is rooted in a simple principle: fix what is actually broken, not what is easy to replace. While many shops and Apple itself default to replacing entire assemblies (logic boards, display units, top cases), Jean-Andre\'s micro-soldering expertise allows him to diagnose and repair the specific failed component on a circuit board — saving customers hundreds of dollars and, critically, preserving their data on modern Macs where the SSD is soldered to the logic board.

He works exclusively with genuine Apple parts for screens, batteries, keyboards, and top cases, and backs every repair with a warranty: 1 year on brand-new genuine parts, 180 days on pre-owned parts and board-level repairs.
