Meet Your Mentors
TOM ROSEMEYER
LEAD INSTRUCTOR
Tom Rosemeyer is a baseball coach with 18-years of experience developing athletes from the youth level to the professional ranks. He began his coaching career as an assistant at the College of the Siskiyous (2007–2009), where he discovered his passion for teaching the game. After returning to the Bay Area, Tom joined MMB, where he has spent the past 16 years working with a wide range of players—multiple big leaguers, dozens of minor leaguers, hundreds of college athletes, and thousands of high school players.
​
ON LEADING THE MMB SCHOOL
“I wish I had something like this when I was growing up. A little encouragement for the young player goes a long way on and off the field. We can improve thinking, actions and results every day with the time we’ll get with these young players.”
Tom has earned a strong reputation for developing players through individualized instruction, demanding yet constructive standards, and a genuine belief in each athlete’s potential. His coaching philosophy is simple and unwavering: every player he works with knows he will do everything he can to help them improve.
WHAT PLAYERS SAY
“He helped me unlock my body on the mound, and free up my mind and approach. His care for each player he works with comes through in each session…and he sees what most people can’t. He makes it about us reaching our potential.” – High School Junior, San Anselmo, CA.

Mike founded MMB in 2002, and today the program analyzes over 300,000 swings per month for players from Little League to the Major Leagues. Travel teams change, coaches change—but MMB remains committed to your player’s development.
WHAT PARENTS SAY
