Mrs. Linda Joyner
Masters in Educational
Policy and Leadership
Marquette University

St. Mary is a thriving Catholic school located in the heart of Menomonee Falls. We are fortunate to have talented and dedicated staff members who are committed to the education of their students and also to their own professional and spiritual growth.

My own educational experiences are rooted in Iowa, where I was born and raised. After graduating from the University of Iowa, I taught art, computer literacy and worked with gifted and talented students. Upon moving to Wisconsin in 1994, I accepted a position at a Catholic grade school where I taught computer literacy and art classes before moving into a new role serving as vice principal. In May 2003, I completed my Masters Degree in Educational Policy and Leadership at Marquette University and began my role as principal of St. Mary, in the fall of 2004.

It is very exciting to be part of such a vibrant school community.

I previously taught for Milwaukee Public Schools and at St. Anthonyís in Milwaukee.

Dr. Cathy Ferderbar
M.S. Science
Marquette University
Cardinal Stritch University

My name is Cathy Ferderbar. I attended St. Mary Parish School as a child and have been teaching middle school science at St. Mary since my daughter was a kindergartener here.

Both my children have pursued scientific career interests. (Elizabeth is now in her last year of veterinary medical school in California. Matthew is a soil scientist for the conservation district in Fairbanks, Alaska.) “Hands on” learning is my passion. Children learn by doing, by experiencing, and then building meaning on the foundation of those experiences. 6th, 7th, and 8th grade scientists actively engage in lab and discussion, role-playing simulations, field trips and project-based learning. Many of the students also participate in science club during which we have built solar cars, learned about the process of cheese-making and created a homemade mozzarella, launched hot air balloons, dissected diverse specimen, grown “salad” and toured a hydroponic tilapia and vegetable greenhouse. Having fun while learning nurtures lifelong learners. My father always called me a “perpetual student.” I recently completed my Ph.D. at Cardinal Stritch University. My dissertation research studied the impact of in-nature and virtual-nature field trip experiences during which middle school students analyzed water quality along
Midwestern rivers, as strategies to develop environmental literacy. We are never too old to continue learning!

TJ Kelm
B.S. Elementary Education
Cardinal Stritch University

Hello, my name is TJ Kelm. I began teaching fifth grade at St. Mary School in 2004 and will be also be teaching 6th grade religion this year. I believe that a teacher should have a positive attitude that shows he or she cares about each individual student. A teacher should be a person that the students can trust and look up to for guidance. Most importantly, a teacher should be a “guiding light” for the students – a person that helps lead the students down the right path in life.

Lastly, I want to instill in children the need to serve others. My philosophy of teaching is that every child is capable of success. It is the teacher’s calling to determine how to achieve it.

It is exciting to teach students many strategies for learning and to see each one of them find success through his or her unique learning style. Their smiles are the best reward.

M.S. – Healthcare Management, UW – MilwaukeeCairnsM
Teacher education courses, Mt. Mary University

Learning a new language gives students a clearer understanding of their own first language. It also provides a window through which they can glimpse the people and cultures of other countries. Teaching a language is equal parts academic exercise and fun.
Teaching Spanish is my third “career.” After working many years in the corporate world, I changed gears and became a full-time mom. My experiences during that time as a Sunday School teacher, “room parent” and Girl Scout leader pointed me toward the field of education. I can’t think of a better job than sharing my love of Spanish with young learners.
When I am not in the classroom or in my home office grading papers, I enjoy reading, gardening and volunteering. I live in Brookfield with my husband, two teenage daughters, and many mascotas (pets).
