Dennis started Pitching Easy around 30 years ago, focusing on private, in person pitching lessons. Beginning in his home state of Connecticut, Dennis has worked with pitchers throughout greater New England and across the country, guiding and mentoring them as they progress through the various stages of their pitching careers. From teaching little leaguers how to grip the ball properly, to guiding teens through high school team tryouts, and mentoring major league prospects as they navigate what it's like to have a career in baseball, Dennis has always focused on teaching the game the right way and developing each athlete in a way that fits their skillset and personality. Now, in 2020, Dennis has brought Pitching Easy Online to reach more pitchers and provide his existing clients with tips and drills they can always have access to.
