Ms. Sandy Muellner

This is my 27th year at LEAP High School. I teach Biology, Medical Careers, nursing assistant, anatomy, medical terminology and introductory science classes.  I  taught Medical Careers, Biotechnology and coordinated a LEAP Internship for St. Paul Connections at St. Paul College for twelve years.

In addition to teaching, my biology experience includes working in a genetics research laboratory and for an immunology company.

My interests are developing new materials for ELL science education, special education, gardening, cooking, hiking, reading and travelling. I am also interested in connecting highly motivated students with careers in Health Science!


  • Student saw parts of the human body, took their blood pressure, explored the museum and watch the movie.

  • The biology students got to see white fluffy DNA from wheat cells.

  • We planted two trees. Many people helped. We dug a hole, planted the tree and poured a lot of water. It was a hot day.
