Having competed and grown through every level of the game — high school, college, professional, Olympic, and beyond — I know firsthand that success is built on hard work, great coaching, and the right relationships at the right time. Those experiences, and the coaches, mentors, and teammates who shaped my journey, are what drive my passion for helping athletes do the same.

Consulting Calls
1:1 calls with players and families to provide clarity and direction.
My goal is to help players and families gain clarity, confidence, and direction — whether that means refining mechanics, navigating the recruiting process, or identifying the right fit at the next level. Through an extensive network across baseball and player development, I'm here to help bridge the gap between where you are today and where you're capable of going. Sometimes one conversation or one small adjustment is all it takes.
Client Reviews
“"Our family has been fortunate to work with former pro Jonathan de Marte for both baseball training and college recruiting. Above all, he is knowledgeable and honest — his eye for mechanics, strengths, and areas for growth is exceptional. He's equally dedicated and organized, and Jonathan consistently follows through on every commitment, especially when it comes to connecting with college coaches."
—Parents of'27 Canterbury School Graduate - Rye Country Day '26
“Working with Jonathan was a huge reason I made it to pro ball. He cleaned up my mechanics, helped me add velocity, and corrected my arm path so I could pitch pain-free again. Beyond his deep baseball knowledge, he genuinely cares about his clients — he still checks in on me regularly. If you're looking to take the next step in your game, I can't recommend Jonathan enough."
—RHP Milwaukee Brewers Organization - Cedarville University '19 - '23 - Northern Kentucky '24
"Jonathan has been an incredible mentor on our son's baseball journey — his ability to break down everything from the basics to the most complex pitching and hitting skills, paired with honest recruiting guidance, has made a huge impact on his confidence, development, and understanding of what it takes to compete at the next level. What stands out most is how much he genuinely cares about his players. Steele's baseball career wouldn't be where it is without Jonathan, and we are truly grateful for the guidance and relationship he has provided our family."
