Mr. Mario DeSanctis

I am very excited to be teaching 4th grade, all subjects, at Bob and Betty Nelson Elementary!  I am proud to be a Nelson Elementary Owl!   I am a retired Air Force officer having served 30 years on active duty in the military.  Following my military service, I also taught at the college level for three years.  I am passionate about teaching at the primary level, and want to help grow future leaders not only by utilizing my skills as an educator, but also my experiences working in the military and in the private sector.


My conference hours are from 1:25pm to 2:15pm.  My room number is 519.
