Professional Instructors

“We encourage the question WHY?”

Our instructors constantly encourage their students to ask the question WHY? “Because I said so” is unacceptable at GBG Training Academy. We want all students to understand WHY they are doing a drill, WHY they are making a mistake, and WHY this is helping them.

GBG Certified Instructors are well versed in these learning domains, as they relate to baseball, making them high-valued instructors. These men and women have themselves mastered skill-sets as it relates to the game. They also have the language and tools to communicate these skills while ensuring your student understands and applies the information!

Every person listed on this page is a GBG Certified Instructor. Many are former athletes who have flourished at major college, minor league and or major league level. All instructors have participated in GBG instructional classes, instructional workouts, as well as completing the intern-instructor program.
