        Leslie has also had the privilege to work with past MLB players as well. Tommy Rowe (Baltimore Orioles and NY Mets), Jose Antigua (Chicago White Sox) and most recently Ramon Nivar (Texas Rangers and Baltimore Orioles). These experiences helped and continue to help Leslie's understanding of mechanics as well as the game itself.

        In 2019, Leslie was chosen as the Head Coach for the Northeast Region Team 2 of 3 for USA Softball's 12U All-American Games. In 2021 and in 2022 she was an assistant coach, under Jaime Wohlbach, for Region 1 Team Stripes. The games are held at the USA Softball Hall of Fame Stadium in Oklahoma City. This event will provide National exposure to elite athletes in the 12u age division and has been designed to identify and highlight the best athletes from across the country. Designation to a USA Softball All-American team is the highest honor a player can receive and instantly brands the player as one of the top athletes in the United States. Only 360 girls Nationwide will have the opportunity to wear the USA Softball Jersey at this elite event.

         As a player, Leslie received pitching instruction from the top instructors in NJ and PA: Roz Bostonian (former pitcher for the Budweiser Belles), Vicky Morrow (All-American at University of Michigan/member of the Pan Am softball team), Carol Erickson (former head coach at William Paterson University), Betty Zwingraf (taught Olympian Michelle Smith), and Darryl Stofflet (Lehigh Valley Fastpitch Hall of Fame).

        In 2009 Leslie opened All*Starz Training Facility in Lodi, NJ. After many years of giving private instruction at local facilities, she felt it was time to have a "home of her own". Although All*Starz is just a 2 lane facility, Leslie and her staff have created a "private" environment where players, parents and coaches come to learn the fundamentals of the game. It is "by appointment only" to ensure that the facility is focused on those who choose to train with us.
