The idea for the TightSpin Trainer fastpitch pitching aid was conceived to help my sister become a better pitcher.
I had trained my sister, Danielle Pieroni since the age of 8 with the help of Cheri Kempf. I was always thinking of new ways to help my little sister become a better pitcher. When I invented the TightSpin Trainer was to be another fastpitch pitching tool for my sister to use to sharpen her skills. It wasn't until her strikeout per inning pitch increased so dramatically that I decided that every fastpitch pitcher needed access to this fastpitch pitching aid.

Danielle pitched her high school to three consecutive state championships and received numerous awards including Tennessee’s Gatorade Player of the Year her junior and senior years. She was also named the Tennessean Midstate Player of the Year during here sophomore, junior, and senior years. She also won 54 consecutive games in a row, a streak that spanned over 3 seasons, and won 84 of her last 86 decisions.

My partner, Kristin Stanfill and I have a combination of 27 years of experience in fastpitch pitching. Kristin and I also have several years of coaching both High School and travel ball including ASA 18 gold travel ball. Kristin coached her high school team to a state championship and I helped coach a travel ball team, the Nashville Nighthawks, to a 3rd place finish in the prestigious Colorado Fireworks Tournament.

Kristin was an elite pitcher during her youth reaching speeds of 59 mph at 13 years of age. Tragically, her pitching career was cut short at the age of 14 when her pitching arm got caught in a garage door hinge. After her injury she focused her time to playing outfield and hitting and earned a scholarship to the University of Alabama, Birmingham.

Also, with the help of world renowned fastpitch softball pitching instructor Cheri Kempf, who trained her younger sister, Kassie Stanfill, a freshman pitcher at the University of Louisville. Kassie pitched her team to a State championship in high school. She also has won numerous awards including All-State and All-Midstate four consecutive years. She was also named Sumner County Player of the Year her sophomore, junior, and senior year.
