IMA Board Members


Melissa M. Droessler

M.Ed., S.A., AMI Montessori 0-3 Guide, AMI Montessori Primary Directress, AMI Montessori Elementary Teacher, Founder

Melissa’s family has lived in Madison for 24 years, but it was in her hometown, just outside of Minneapolis, Minnesota, where Melissa first experienced Montessori education: from the ages of three to six, Melissa attended Golden Valley Montessori School.

After completing her undergraduate degree from UW Madison, Montessori found Melissa again as she was applying to graduate school for social work. As an assistant in Carrie Marlette’s classroom, Melissa became fascinated with the children and their excitement for their work. Realizing that she was too old to be a student again in a Montessori classroom, Melissa decided to take the Montessori training and become an AMI Montessori elementary teacher with a Masters in Education in 2005.

After teaching in Madison for many years, Melissa received her state teaching license and taught for the Milwaukee Public Schools at Craig Montessori School until her first child, Roman, was born. Passionate about early childhood development and education, Melissa completed her AMI Montessori Primary training in 2009. Prior to completing the AMI Montessori Assistants to Infancy training in 2021, Melissa completed her graduate certificate in School Administration from Johns Hopkins University. Melissa thoroughly enjoys speaking Spanish with her students, as well as playing the flute and piano in her classrooms. Above all else, Melissa adores working and learning with families and children of all ages.

Melissa has been in Montessori Primary and Elementary classrooms for sixteen years, she has served on the board of the Montessori Institute of Milwaukee and as Vice President of the Wisconsin Montessori Association, and she is excited to be a part of this growing AMI Montessori community in Madison!


Carrie Marlette

M.Ed., AMI Montessori Elementary Teacher, Founder Emeritus

Carrie earned a Journalism Bachelor of Arts degree from the University of Wisconsin-Madison in 1978. She then completed the Association Montessori Internationale training at the elementary level (for students ages six through 12) in 1995 and received her M.A. in Education at Loyola College in Baltimore, MD that same year. Carrie also attended Edgewood College in Madison to study the Orton-Gillingham program to help students with reading, spelling, and writing.

Carrie taught at Madison Central Montessori School for 15 years. During that time, she served on the curriculum committee and the Retention Task Force. Both of Carrie’s children attended Montessori at the primary level and her son continued in the elementary class through the fifth year. Implementing true Montessori methods with a thriving “Going Out” program is Carrie’s goal for IMA.

Carrie has lived in Madison for more than 30 years. She fell in love with the city as she studied at the university and met her husband soon after graduation. The Marlettes chose to raise their children in this progressive city filled with education, diverse culture, and arts. In her spare time, Carrie practices Scottish Highland and other dance forms and is one of the founders of Gaelic Fusion Dance Company. Carrie and her family love to travel and enjoy nature.
