I have known Dr. John Bagonzi for over 30 years and have consulted with him countless times - working with him during the summers while in high school and college, through my professional pitching career and while a professional pitching coach myself, Coach Bagonzi has been an invaluable resource for me.  His tremendous knowledge of the science of kinesiology, and how it is applied to proper pitching mechanics, combined with a lifetime of playing and coaching baseball puts him in an elite group as far as I am concerned.  His passion for learning and teaching coupled with a great sense of humor results in a truly unique person. John is someone I feel most fortunate to have been able to call coach as well as my good friend. He is a genius in pitching,

The best pitching coach in the east; a pro's pro, very intelligent about pitching concepts, great overhand curve (a thing of beauty) " the best I've ever seen " I chased him all over the continent trying to sign him.  Had all the goods. Once saw him pitch both ends of a doubleheader with a no-hitter in the second game.

Mechanics are essential in becoming a good pitcher.  Although mine have been refined throughout the years, it all started with Coach Bagonzi.

No one knows more about pitching than John Bagonzi.  He works with all our pitchers.  I wouldn't have anybody else.

John Bagonzi has been a frequent contributor to Coaching Management Magazine, a publication for high school and college coaches.  His articles always provide insight into the game and hands-on advice for old and new. He always appears in our yearly baseball edition.

John is undoubtedly the best-ever coach in New Hampshire.  His teams were absolutely prepared, and played with class and precision; they were great to play against.  His pitchers always had great curveballs. Though they always beat you , you never would have known after the game, they won with class.
Bob Savage, Major League Pitcher, Philadelphia Athletics

I like Dr. Bagonzi's theories and agree completely with him on the push-off concept.

John is far and away the best coach ever in NH. He turned our baseball program around instantly and we've been going strong since.  He knows pitching better than anyone I know of.
John Clark, Athletic Director and Vice President, Plymouth State College

He made me ready for pro ball when I was 17 and everything he taught me I used , I won 4 of my first 6 games at the Class A level .He is an incredible motivator.
Steve Blood, Minnesota Twins (won 50 games in pitching Woodsville High School to three state championships)

Bags and I were experimenting with all types of pitches long before people knew about them.  John was always ahead of his time on development of certain pitches.
Bob Smith, Major League Pitcher, Boston Red Sox, Detroit Tigers, and Pittsburgh Pirates

Coach Bagonzi is a perfectionist. He made me understand spins so well that I had two quality pitches when I went to Class A ball and won six of my first seven games.  As a coach, John Bagonzi always pushed us beyond what we thought were our limits.  As athletes, we would do anything he asked of us, out of respect for him. The lessons he taught me on the court and on the field are still with me now - in how I deal with  work, and the problems that come up.  He shaped players' characters to believe they could do anything they wanted, as long as they were willing to work hard.  My opportunity to play professional baseball was largely due to John teaching me how to throw a curveball.
Jim MacDonald, Major League Pitcher, Houston Astros

John and I played together years ago with the Corning Red Sox - he had a great curve.  I agree with him totally on the drive-off the back leg concept.  I also share his thoughts on throwing inside and using a two-seamer and four-seamer in the north/south style of pitching.  He's a great pitching technician.
