Gabrielle Palermo

Gabrielle Palermo  - Co-Founder/Director - Kindergarten Teacher


Gabrielle graduated from Mars Area High School in 2001 and attended the University of Pittsburgh, completing her undergrad in Criminology. She continued her education to receive an Elementary Education Certification and then her Masters in the Art of Teaching.  After completing her Masters, she became a Behavior Specialist Consultant for several wraparound companies. In 2013, she completed all her trainings and clinical hours to become a State Licensed Behavior Specialist. Through visiting multiple daycares and schools, she has observed a huge deficiency in a student’s ability to problem solve and process information.  Gabrielle has adopted the theory that, "There needs to be more hands on experiences and the transferring of skills to real life situations." So many children are getting lost in the pile of worksheets that they have to complete and having to learn verbatim what the curriculum says they should know. There is a better way to get our children to gain knowledge and that is through the STEM based principals.  Children will finally be excited to learn when attending STEMsteps  school.
