Our Story

15 years ago, Fred Hoefnagel sat in a room with an HLA Laboratory Director with the intention of designing a Laboratory Information System.

Fred had experience in designing software, and expertise in programming. After months of interviews, iterative testing, validation, improvement, and recoding, mTilda was born. That spirit of customization and specificity for our partners continues in the mTilda culture. And while mTilda was originally designed as a custom solution, Barbara and Fred have constructed and improved the architecture, functionality, and form of mTilda. Every lab can benefit from its robustness, comprehensiveness, and simplicity.
