Mauro Castillo, MD

I trained as a physician in the Dominican Republic, then moved into strength and conditioning. In the Texas Rangers minor-league system I worked daily with coaching, medical and mental skills staff in English and Spanish, and built the Bridge program that moved players from rehab back to full training.

Then came a performance fellowship with the Texas Legends. Today I build tools that turn athlete data into staff decisions, and I write about what holds up in practice.
