Justine Siegal, PhD
1st Woman to Coach Men's Pro Baseball
A Serial Disrupter
Keynote Speaker. League Founder. Pro Baseball Coach. TV Baseball Consultant. Nonprofit Leader.
​
When she was 13, Justine's coach told her that girls are only supposed to play softball - not baseball. At that moment, she vowed she’d never quit. At the age of 16, she set her sights on becoming a college baseball coach. Despite being ridiculed, laughed at, and told no man would ever listen to a woman on the baseball field, she worked toward her goal, growing even more determined to realize her dream.
​
After earning her PhD in Sport Psychology from Springfield College, Justine became the first woman to coach for a Major League Baseball Organization (Oakland Athletics, 2015) and to throw batting practice to a MLB team during Spring Training (Cleveland Indians, 2011). She coached for Baseball United, a men's professional baseball league in the Middle East and South Asia (2023-24). Off the field, and onto the screen, she served as a Baseball Coordinator for the tv show, A League of Their Own. In 2025, Justine co-founded Women's Pro Baseball League, which launches May 2026.
​
Justine is giving back to the next generation with Baseball For All, a nonprofit she founded to create access for girls to play, coach, and lead in baseball. She is an inductee of the National Women's Sports Museum and has been named an Everyday Hero by espnW. Her A's hat is in the National Baseball Hall of Fame in Cooperstown and her jersey is in the Smithsonian. Justine will tell you her greatest achievement is raising her fiercely independent, 27-year old, daughter.

People in MLB"

“She has blazed a trail for many women in baseball. The work she has done allowed doors to open for others. There are a lot of women coming up through the ranks [of professional baseball] now. For me, Justine planted the seed.”
– Elizabeth Benn, former MLB senior coordinator of player programs for baseball development & diversity
Justine Siegal is an amazing visionary, change agent and social justice crusader.
Her story is a remarkable one that all women--and men--should hear. The amount of challenges, discrimination and hostilities she faced would have crushed the normal person. But Justine isn't normal. Her strength to be kind in the face of anger is a true inspiration."
