GTC Mission Statement: "To proudly provide fun & educational programs, products, and experiences all with the goal of inspiring "kids of all ages" to explore and learn more about the sciences"

About us:

Geologic Times Corporation proudly provides fun & educational programs, products, and experiences for "kids of all ages" all with the goal of inspiring "kids of all ages" in the sciences. Every program and activity we provide has educational elements carefully designed into them. But, these programs are so much fun; few even realize they are learning things too. That’s not by mistake, it’s by design and it works! This clearly costs us more to do, but it provides true value and benefits that simply cannot be measured monetarily alone... There can always be cheaper options out there, but you would have a tough time finding a company that offers more value or that can do it better!


Our history:



Our efforts to inspire “kids of all ages” in the sciences which all began back in 2006. Yet, we still have barely scratch the surface of master plan. While it’s good to look back sometimes, our eyes are clearly more focused on we can do today and, in the future, and always striving to reach and inspire far more “kids of all ages”. With your help and support, we will do just that!

    Our team efforts to inspire “kids of all ages” in the sciences creates the unique opportunity and ability of making a long-term positive impact on others. Just a chance of making a positive difference in a single person's life makes all of our hard work and efforts worthwhile, and I'm happy to report we have achieved far more than that; it's something my staff and I are very proud of.

    Hi, I'm Iszi! I have a background in ecology and a passion for sharing the love of the planet we live on. I believe that one of the best ways to encourage people to engage with the sciences is to make it entertaining and fun, as well as relevant to our daily lives.

    Hi, I’m Julia! I have a bachelors degree psychology from UMBC and I plan on pursuing higher education in the field of child development/education.

GTC’s mission statement stands very close to my heart, and I am honored to be part of the GTC family.

    My name is Dr. Jessica Lawrence Wujek, I am a geologist and paleontologist. I love to study marine reptiles, specifically ichthyosaurs. I received my bachelor's in geology at Ohio Wesleyan University in 2006, my masters in geology/paleontology from Bowling Green State University in 2008 and my PhD in geology/paleontology from University of Southampton in 2018. I joined this company because I wholeheartedly believe in its mission. Spreading knowledge of science is incredibly important.

    Hazel M Campos-Braus

    Educational Program Assistant Manager,
    Educational Program Presenter

    Hi, I’m Hazel! I am a STEM/STEAM/Science educator and I have a Bachelor of Science in classroom education. I’ve loved the sciences all of my life, but really started focusing my interests back in the Science and Technology program in my high school. I’ve served as a Team Manager for Destination Imagination, a leader for Boy Scouts and I am still currently a leader for Girl Scouts. I’ve worked as a Mad Scientist, a science teacher, and as the STEM educator with iFLY Indoor Skydiving, to name a few positions I’ve held. But my interests have brought me here to the GTC Rock Shop. I believe in their mission to bring the sciences to “kids of all ages” and I look forward to sharing my love of science with you all! SCIENCE ROCKS!!!
