The instruction and knowledge my son, Michael, has gained from Mark Sheehan has been invaluable as he grows in his pitching prowess. Thanks to Mark and the concepts he espouses from the National Pitching Association, my ten-year-old has become one of the best pitchers on his team, learning to throw strikes at a rate that to me has become surprising in its efficiency.

Mark came highly recommended by a friend and we have never had a reason to second guess our decision or look for another option. Mark and his 5 Tool staff have been great.

My father signed a contract right out of high school with the White Sox so pitching and baseball is in the family blood. I had my own theories on pitching and was a successful pitcher myself, but by college had thrown my arm out. At first, I had questions with a couple of things my son was learning, but very quickly came to understand Mark's system and am extremely glad I did. I watch kids with their wind ups and their body is going two different directions, struggling to throw strikes. I am glad my son has developed a solid base through Mark and 5 Tool.

At a young age it is important that my son understand the fundamentals that will help as he grows. Mark's technique is a proven success and has my son throwing the ball with control and confidence.

Mark has done a great job getting to know my son and explaining the techniques needed. He makes practice sessions fun and enjoyable which makes learning easier.

Mark is a vary talented teacher and he will make sure your youngster gets off on the right track.
