High School Transcripts from Montessori School

Former students from RaNae Stellmon's Montessori School - Coeur d'Alene, Idaho

The school is no longer in business.  It was active in the 1970's and 1980's.  It went from Pre-School through High School Graduation.  RaNae Stellmon passed away in 1990.

However her daughter,  Marti Mortensen, is the permanent record keeper for student Transcripts.

Marti is working to provide the Coeur d'Alene School District with a digital set of these records for permanent archival access.

It will be announced here when these have been provided.  Expect it to be sometime in 2017 school year.
