Siena Trehy, aka Ionic Bond

Siena has been in the business of making science fun for kids FOREVER! Siena’s Dad started ‘Mr. Bond and the Science Guys’ in Nashville, TN when she was 4 years old, so she grew up in and around the world of experimentation and sharing the joy of learning with other kids. As an adult, Siena moved to Baltimore to study Environmental Studies and Anthropology at Goucher College. Her main focus was to learn how to share concepts of sustainability with others, something that she has certainly integrated into the Science Guys curriculum. Siena is also an avid fiber artist, making clothes and other stitch art. She is a Co-owner, Business Manager, and Teacher for the Science Guys of Baltimore.

After college, he taught music lessons and ran a company called Music Together, teaching music to infants and toddlers. He went on to move to Nashville, where he met the Bond family. He mentored under Keith (the original Mr. Bond) for 5 years before moving to Baltimore, marrying Siena, and starting the Science Guys of Baltimore.

Travis Henningfield, aka Travity

Travis is Baltimore, born and raised! He attended the Friends school of Baltimore for High School, then moved to New York City to attend the Pratt Institute of Art. Travis loves all art, but really enjoys sculpture and found object art, as a way to make everyday objects useful and beautiful. He also worked as a Chef in NYC for 6 years, before moving back to Baltimore and finding his way into the Science Guys. He is our lead teacher for after-school clubs, camps, and birthday parties and has helped develop our Kitchen Chemistry and Science of Art clubs, among many others. Best of all, he’s got a big colorful mohawk, and we LOVE it!
