Matthew Mistretta

Owner, Total Diamond Performance Director of Player Development, Louisiana Mariners Baseball


Mistretta opened a second Total Diamond Performance location in Baton Rouge this year featuring four fields, covered batting cages, and a 20,000-square-foot indoor facility. He serves as a baseball performance consultant for the Oregon State baseball program and is a mental performance coach for the baseball programs at Sulphur, Live Oak, and Dutchtown high schools, teaching players how to develop a competitive process to overcome adversity/failure, get the most out of their performance, and enjoy the game more.

Personal motto:

“We before me.”

Podcast I recommend:

“WorkLife with Adam Grant” and “Dare to Lead,” by Brené Brown

Go-to advisers:

Mitch Canham (Oregon State head baseball coach) and John D’Angelo (CEO of Investar Bank). They’re extremely successful in their field, high-character people, and they understand the importance of a positive, healthy organizational culture.

Goal for 2025:

Learn American Sign Language to reach the hearing-impaired community with an interest in baseball or softball.
