Our Team

Our staff strives to provide students with exciting and engaging space mission simulations and other STEM activities

Ron Bush, President and CEO

Inspired by a student teacher he had in elementary school, Ron was always interested in science. He spent the first 12 years of his career sharing that passion with his students as an elementary and middle school science teacher. Now, after seven years at Challenger, including the past three as Vice President of Education at Challenger, Ron has been elevated to CEO and President. Ron’s favorite Challenger program to run is the Night Sky planetarium show. No matter what their age, learning about the night sky is a great way to spark a sense of wonder and curiosity in students. And just like it did for him, Ron hopes that spark leads his students to a lifelong fascination of the creation around them. Ron spends as much time as possible enjoying the Colorado mountains with his wife, Stephanie, and their three boys. As a native of Pittsburgh, PA, Ron bleeds “Black & Gold” for his beloved Steelers, Penguins, and Pirates.

Becca Manis, Vice President of Education

Becca has been a part of the Challenger network since 1999 as both a Center Director and Lead Flight Director.

Hannah Armstrong, Flight Director

Raised in a family of aerospace and space flight enthusiasts, Hannah developed a passion for astronomy early in life. She followed this passion to the University of Colorado Boulder where she graduated with a Bachelors in Astrophysics with an emphasis on planetary science. While at the university, Hannah taught astronomy labs and led telescope observation sessions at the Sommers-Bausch Observatory. At the Challenger Center, she serves as a Flight Director, facilitating Makerspace programs and directing planetarium shows for students of all ages. Her favorite program to run is the Solar System Tour planetarium show. This show educates students on the unique and fascinating characteristics of each planet and provides a greater perspective of the solar system’s place in the universe. In the future, Hannah hopes to become even more involved in science communication and outreach, focusing on accessibility and advocacy in education, all while sharing her love for the cosmos. In her free time, you can find her working on an art project, reading a good book, or watching a movie with her cat, Suki.

Jerard Carney, Flight Director

Jerard graduated from the University of Technology (UAT) majoring in Artificial Intelligence (AI) programming. His passion is optimizing and simply fixing things to be their best versions. Prior to finding his passion in technology, Jerard was a medic in the Army, and an EMT for Children’s Hospital Colorado. He is excited that being a part of the Challenger Crew allows him to turn hobbies, like 3D printing, astronomy, and Arduino programming into practical applications. His "nerdy game side" likes video games, Dungeons and Dragons, and Warhammer and even this skillset will help accentuates Challenger Colorado's center and programs. Jerard strives to ensure that others are taken care of and a motto he lives by is “Hic Servire”- Here to Serve. He believes everyone has the potential to be their best self and that this takes discipline, sacrifice, and determination and utilizes this philosophy while flying all of his Challenger programs. When not at work, you might catch Jerard hanging out with his wife and 2 sons, in his garden, or focused on one of his many hobbies.

Stephanie Carriere, Flight Director

Stephanie is passionate about encouraging the kids of today to be the scientists, astronauts, engineers, and health care professionals of tomorrow. Her background studying neurobiology and child development at UC Davis give her a strong foundation to effectively teach children how fun and interesting science can be. She loves working at Challenger Center for the opportunity to watch kids overcome obstacles, encourage them to work together and see their joy when they achieve something they didn’t think was possible for them. Her favorite parts of the missions are the emergencies that kids have to work together to resolve, as the looks of pride on their faces when they “save the day” are priceless. When she’s not at Challenger Center, Stephanie also works as a pediatric emergency department nurse, where she uses her knowledge and skills to help children get back to feeling like their best selves. In her free time, Stephanie loves running marathons, reading good books and spending time with her family and dogs.

Patrick Gaddis, Flight Director

Born and raised on Florida’s space coast, Patrick had a front row seat to the launches of the Space Shuttle program from his backyard. Ever since, he has been known as a self-ascribed space junkie. Patrick then moved to Colorado, where he completed a BS in Physics/Astrophysics with a minor in education in 2016. Patrick first started with Challenger as a summer camp instructor along with a teaching position at Vista Ridge High School in District 49. After 6 years as a Science/Math educator, he now works full time at the center. Patrick’s favorite program is the Mars Simulator Mission. In his free time, Patrick can be found watching a good movie or playing the latest games.

Mary Kincaid, Flight Director

After graduating from Colorado State University and receiving her teaching degree from Hardin-Simmons University in Texas, Mary began her rewarding teaching career as an elementary school teacher. Mary has always loved working with kids and tapping into their imaginations. She sought out a position at the Challenger Learning Center after hearing about it from her own kids….who each thought it was the best field trip ever! Mary’s favorite mission is Expedition Mars as it is engaging, involves teamwork, and is downright fun. When not running a mission, you will find Mary refinishing furniture, gardening, fostering kittens, or hiking in the beautiful mountains of Colorado. But, her hands-down favorite thing to do is relaxing on her patio with her husband and three amazing kids.

Leni Schlieper, Flight Director

Leni always knew she wanted to be a teacher. After graduating from Cal State Fullerton and getting married, the USAF sent her husband (and her) to Victorville where she started her career. After living in Nevada, North Carolina, England, Alabama, Colorado, and Alaska (and having taught in most), it was in Colorado where Leni discovered the power of STEM learning with her Kindergartners. This catapulted her to plan and host school-wide Engineering Days with a small army of STEM professionals supporting. She wrote and received two grants for STEM endeavors impacting hundreds of students. For three years, she coached 4th and 5thgrade robotics teams, going to the state championship twice. Later as a 4th grade teacher, her first class of 4th grade students performed their first mission with Challenger Learning Center. She, and more importantly, her students were hooked. Leni is committed to introducing ALL students to STEM and inspiring a love of learning. Leni and her husband boast three grown children and a son-in-law. Having had the gift of living all over, they love to travel. Locally, the family loves the array of Denver museums and the Switchbacks. She and her husband are often looking for the next best Indian restaurant comparing each to the tastes they got to savor during their years in England. She is also a bit of a Harry Potter fan.

Kendra Thompson, Flight Director

Born and raised in Colorado, Kendra always had her sights set on becoming a teacher. After finishing her B.A., she went on to earn her Master of Science in Curriculum and Instruction, with an emphasis in secondary Social Studies. She joined Challenger Learning Center in 2019 and her love of teaching quickly broadened into the STEM field. Kendra’s favorite part of teaching is encouraging critical thought and this opportunity presents itself in every aspect of Challenger’s curriculum. She equally loves running simulated missions and expanding STEM knowledge in all the MakerSpace activities Challenger has to offer. When she’s not at work, you can find her spending time with her husband and kids enjoying all that Colorado outdoors has to offer or volunteering at her kids’ school.

Natascha Wiseman

Once upon a time, many years ago, there was a little girl who LOVED watching Star Trek with her dad. (A dad who just so happened to moonlight with NASA and would bring her and her siblings autographed astronaut pictures and mission patches). That little girl grew up to walk many paths – soldier, athlete, teacher – before finding and falling in love with Challenger. And so, her story with space comes full circle. Today, as a Flight Director, Natascha brings a deep passion for engaging students in hands on, experiential learning which she believes is a core element embedded in all of Challenger’s programs. She looks forward to melding and applying her unique skillsets, acquired from her years spent as an Intelligence Analyst in the U.S. Army and then the STEAM teacher at Legacy Peak Elementary, to bring Challenger’s missions and explorer labs to life for all students. While she doesn’t have a favorite program just yet, she knows one thing with absolute certainty - her days here are sure to be filled with adventure and learning! When she’s not at work you’ll find her enjoying time with her husband and daughter at their home nestled deep in the pines.
