Baseball Camps in southern California with Baseball Instructor, Mark Mainini

"I can say without hesitation that Mark Mainini has been the finest baseball instructor for my teams and for my two sons.  His knowledge of the mechanics of hitting, combined with his patient demeanor and RightView Pro system yields optimal results for young ballplayers."  - C. Chance   


"I have known Mark for about 8 years. I met him through Don Slaught at a 3 day baseball convention in Texas.  I was so impressed with his knowledge and teaching skills that I arranged for him to fly to a newly constructed 6000 sq .ft. indoor hitting facility in Beaumont,TX many times.  I wanted Mark to train my instructors as well as myself. He was magic with the students of all ages 6-20 with his ability to have confidence, encouragement and patience with each student at their own skill level.  My daughter who was a student of Mark's has flown out twice from Beaumont, TX  to Los Angeles to train with Mark as we feel it's the best coaching has to offer."

.....They are both better pitchers and improved hitters, who have an improved command of situational baseball and now own an  understanding of the finer details of the game of baseball.  My boys are huge fans of Coach Mark, not only because of what he teaches them, but how he interacts with them. He has contributed significantly to their love of the game."    - R. Rosas
