Lisa Jaster is an American soldier, combat engineer, and one of the first three women to graduate the elite United States Army Ranger program in 2015. One of the most difficult combat training courses in the world, Lisa was the first reservist to complete the course. She graduated at age 37, while the average trainee age is 23. Lisa, an athlete focused on strength training and Brazilian Jiu Jitsu, has a deeply rooted understanding of the importance of perseverance through continual progress and growth, as well as an ingrained respect for camaraderie and selfless service stemming from a noteworthy active-duty career (including tours in Iraq and Afghanistan). 

Prior to receiving her esteemed Ranger tab, Lisa worked as an engineer with Shell Oil in Houston and an Army Reserve individual mobilization augmentee with the U.S. Army Corps of Engineers. Her background in both the military and corporate worlds allows her to connect with any audience to create a memorable experience. Lisa initially was commissioned in the Army in 2000 after graduating from the United States Military Academy at West Point and returned to the reserves in 2012 after a 5-year hiatus from serving. She volunteered for combat training when she discovered the Army Ranger course was being opened to women for the first time in 60 years as a U.S. government experiment to see how women would fare in the notoriously brutal program. Lisa is the recipient of numerous military accolades including two Bronze Star Medals and the Meritorious Service Medal.

Lisa left active duty in 2007 and started a family and civilian career with Shell but returned to the Army as a reservist in 2012. Lisa holds a BS and MS in Civil Engineering. She focuses her efforts on training management teams, executive coaching, and keynote speaking. She also works with Leading Authorities, LLC as a keynote speaker. She plans to release her first book, “Delete the Adjective,” at the end of 2022.
