Our Background

First and foremost, the Science Guys is a family company!

Siena Trehy and Matt Simms started the Science Guys of Baltimore in August of 2016. Siena and Matt met in Nashville, TN working for her father, Keith Trehy, who started the Science Guys of Nashville 20 years before. Siena grew up in the world of Science Guys and Matt has been in the family business for 8 years! 3 years after Siena moved to Baltimore to go to college at Goucher college, Matt came to begin their new adventure starting the Baltimore branch! 5 years later, The Science Guys includes Matt and Siena at the helm, with an amazing team of Science Guys who you will see doing experiments all over town!

Now the Science Guys of Baltimore offer exciting and accessible children’s science programming year round, including summer camps, birthday parties, after-school clubs, in-school workshops & assemblies, and special event shows throughout the Maryland and DC area.
