Adam Sieminski
Co-Founder, Technology / Photo / Video

Adam grew up with Will in Washington, DC. At a young age he became interested in computers and before entering college he had earned numerous professional certifications from Microsoft (MCP, MSCE [NT4, 2000, 2003], MCSA, MOS), Cisco (CCNA) and CompTIA (A+, Net+). He also is an avid photographer and videographer.

Graduated Landon School for Boys in 2000. Graduated University of Arizona in 2006 with BAs in Spanish and Business. Adam played tennis competitively as a junior but is now terrible. Most ten year olds can beat him. Adam and Will became best friends in first grade at the Beauvoir School in Washington, DC. Adam’s LEGO fortresses were better than Will’s and this left Will with a permanent inferiority complex.
