I joined St. John the Evangelist's community as principal for the 2021-22 school year.  I look forward to serving you as we grow in faith and knowledge. I became an educator 17 years ago with the goal of making the world a better place one student at a time. I still have the same goal today. I want to be a part of a team that provides a Christ centered, stimulating, challenging, and safe learning environment that will develop future leaders. I am comfortable working with students of all ages and enjoy guiding students to successful outcomes. I have provided teachers support and coaching throughout my years in education, and look forward to continuing to help others develop their talents to best serve our students. I enjoy interacting with people and look forward to developing strong, positive relationships with you to help our St. John’s community to grow spiritually and academically.

St. John the Evangelist has a reputation of being a place to grow in education and faith as a Christian school, home and community and I want to share in that. 

I have been an Administrative Assistant for 20+ years in the Archdiocese of Milwaukee and prior in the world of banking. I can honestly say this job is my calling and I love sharing my time and talents with the students, families and faculty. One of the most rewarding things from working in the school is to see former graduates in the outside world and share where their lives have taken them.

I am a mother of two daughters and three grandchildren. They are my biggest accomplishments and joy.

As an Early Childhood teacher, I believe it is important to help children discover the joy of learning through play. In order to assist each child on their learning journey, students will have a variety of activities that coincide with what we will be learning in the classroom. For example, playing alphabet or number bingo, using playdough to create letters, numbers or shapes, and other fun games.

I strive to help children reach their fullest potential by providing them the tools and resources to grow as an individual, as well as together with others. We will focus on the following social skills: learning the difference between right and wrong, using words to express feelings or needs, sharing or taking turns, playing alone or together with other children, and becoming independent. I believe these social skills are important for children to learn to respect, gain independence, and how to cooperate with each other. Together we work towards building a community with one another and growing with our Catholic faith.

Our Catholic faith is very important to me and so I try to incorporate a deeper understanding of the faith and profound love of God throughout the whole school day. We are all called to live holy lives and it is my goal that students strive to always follow in Jesus’ footsteps and become the person and the saint God wants them to be. It warms my heart when a young student tells me he/she wants to become a saint and go to heaven!

I love teaching K5 students because they are so eager to learn. Their minds are sponges that soak up any information that you give them. My goal is to keep learning play-based and fun while still helping students strive to be independent in their school work, solve problems, work well with others, use their imagination and persevere through something that they struggle with. My classroom is a place where the students should feel free to express themselves in many ways. It is a place where students can safely make mistakes and then to find a solution. My favorite thing is when a student is excited by a discovery they made and wants to tell  everyone!

I am so excited to be teaching at St. John the Evangelist.  This is the parish that I have called home for the past decade.  I have over ten  years teaching experience.  My children attend school here at St. John the Evangelist.  They are Max, Michaela, and Josiah.  While my children were small, I was a stay-at-home mom.  I feel very blessed to have a  career that I truly love and to teach in the grade that I love.  My passion is teaching children how to read! I also feel blessed to be able to share my Catholic faith with my students.  Catholic education is unique.  It not only prepares the student academically, but spiritually as well.  This aspect of Catholic education sets it apart from other schools.

When I am not teaching, I enjoy spending time with my family.  We love to play sports, hike, and watch movies (Marvel movies are my favorite!)  Some of my hobbies include: weight lifting, running, kickboxing, cooking, studying foreign languages, woodworking and crafting with my kids.

I am truly blessed to be working at St. John the Evangelist. I graduated from Alverno College in 1995. I have been married for over 30 years and we have three beautiful adopted children. We are a very close family and love playing games together and going on adventures when we can. We are very active with dance, volleyball, or just working out to stay healthy and strong. 

I have been a classroom teacher for over 20 years before coming to St. John the Evangelist. Most of my years have been with 3rd grade, but when I found out about the 2nd grade position being open I knew God was calling me. Second grade is a very special year because the students prepare and receive their First Reconciliation and First Holy Communion. I feel so special to be called to help the students as they receive these two special sacraments. My faith is so important to me. This comes out throughout the day. It can be seen as we work together on reading, writing, math, or religion class times.

Thank you for entrusting me with your children to grow in their academics and faith.

I am happy to be a part of the St. John the Evangelist School community.  I grew up in Omaha, Nebraska. I graduated from the University of Kansas with both a B.S. and an M.S. in Education.   My husband and I have two daughters. Our family is very active in parish life at St. Anthony on the Lake, in Pewaukee, and both girls are enrolled in our parish school.

The mission of our school is “St. John the Evangelist: a community modeling and nurturing Catholic values and academic excellence in partnership with families”.  Truly our ultimate mission is to help each other get to heaven! I firmly believe that in a Catholic school, we not only teach our children math, reading and science, we teach our children how to be effective members of the Catholic community.  

As a teacher it is my duty to get to know your child and help them be the best they can be.  Teachers identify strengths and growing edges. It is my earnest desire to impart to your child the tools to become successful lifelong learners.

Catholic Education is a precious gift from God.  I am so blessed to be teaching at St. John the Evangelist and continuing my journey of Catholic Education.  I was born and raised in the Chicagoland area and am a diehard Cubs and Bears fan (just had to get that in).  I made my way to Wisconsin when I attended Marquette University.  I graduated from Marquette with a BA in Psychology with a minor in Criminology. 

After moving permanently to the Milwaukee area, I began working in the field of social work as a foster care case manager at La Causa, Inc. which is located on the near south side of Milwaukee.   After spending a few years in social work, I decided to return to school to earn my teaching degree.  After receiving my teaching degree, I started working at a Catholic School on the near south side of Milwaukee and have been teaching in Catholic Schools ever since. 

For me, the most rewarding part of teaching in a Catholic School is being able to share this spiritual journey with my colleagues, families and students; while knowing that it is God who is guiding me on this mission.

I have been teaching 4th grade for many years and absolutely love it. Fourth graders are extremely enthusiastic and eager to learn.  It is my job to nurture their enthusiasm and to create a classroom environment that encourages students to take risks, develop a growth mindset, and to attain academic goals.  I am looking forward to getting to know and learn from each of my students during the school year.

As a product of 17 years of Catholic education, I have been drawn to teaching positions in which I can express my faith and use it to build deeper relationships with others. I am a very enthusiastic person who enjoys service-based learning. I enjoy sharing my knowledge of God and the Catholic faith with others; especially sharing my personal faith journey with the future of the Catholic faith – our youth. I have taught religious education both in Catholic elementary schools and in my parish’s religious education program.

I believe that all children have individual needs that should be known and addressed by educators to ensure that students receive the best possible education. Throughout my teaching career, I have worked with students of various levels and ages and have incorporated the use of manipulatives, technology, audio and visual tools, and various grouping strategies to ensure that all students succeed in meeting their educational goals. I also believe that my faith can inspire and energize me to look outside of myself and be the hands and feet of God on earth.

I have always set high expectations for the students that I have been provided the opportunity to guide and assist through their our educational and faith journey. I ask the students to set personal goals during the first week of school and post these goals as a constant reminder that we need to work together to meet and exceed these goals. I provide the students with a safe and respectful environment where they can feel comfortable to take risks and learn from their mistakes. Students will learn that their educational success depends on their willingness to follow all class expectations which include completing their assignments, paying attention in class, participating in classroom discussions, and preparing themselves appropriately for assessments. Coming prepared to learn with the proper materials and a positive attitude is a requirement for all members of our classroom community.

I believe that my responsibility as a teacher is to provide the guidance and encouragement each child needs to develop the knowledge and skills that will help him or her succeed. Each child is unique, especially in how he or she learns best. I draw from my own experiences as a student, and from research and best practices, to create an environment in which each child can grow as an individual. I try to involve students in decisions in the classroom to foster independence and to encourage students to feel ownership over their education. Middle school students have a lot to say, and I aim to help my students develop their voices, through speaking, listening, reading, and writing, so that they can become articulate, well-educated citizens of society.

I feel blessed to teach in a Catholic school where God is at the center. I love that my job encompasses more than just academics; as a teacher at St. John the Evangelist, I have the opportunity to help children develop socially and spiritually, as well. Prayer, games, discussions, and questions are all a part of the classroom as we build a community of Catholics searching for knowledge and truth.

I came to St. John the Evangelist in 2017, with more than 20 years of experience in Catholic Education. After a brief career as a lawyer in Chicago, I realized my future lay in education.  I received my education credentials from Loyola University in Chicago.  After working as a substitute teacher in Chicago area schools I moved to Greendale, WI in 1996 with my wife, Dr. Sandra Scalzitti.  We have a child in high school and another beginning college, so I know how education has changed over the years in ways that affect families as well as teachers.  I found a job teaching 7th and 8th grade at St. Matthew’s in Milwaukee (later Prince of Peace School).   My move, and my rooms here, reflect my passion for science.  I believe science is vital for understanding the world around us.  In my room students will pursue investigations into the world around them.  I believe science should involve hands-on learning, coupled with an understanding of the history of science.  Students will learn and apply the scientific method throughout the year.  My science lessons are tailored around the Next Generation Science Standards.  To paraphrase this large set of information, my science instruction is based around a few key ideas.

Teach less, but teach it deeper.  We may not learn the name of every mammal in North America, but we will learn how animals are adapted to their specific environments.

Cross Cutting Concepts; develop students’ ability to do things such as find cause and effect relationships whether they are studying how plants grow, water changes state, or continents drift.

We will develop scientific skills:  making and using models, gathering and analyzing data, investigating problems and designing solutions. 

Evaluating sources of information.   Science is based on fact, not opinion.  We will learn how to determine the difference between these two things and how to find facts among various sources of information.

The role of being an educator runs deep in my family.  My father was a Spanish Teacher and taught high school and at the college level in Green Bay at St. Norbert's in DePere.  My sister is a bilingual education teacher in Milwaukee and I have extended family in education as well. A "flip of the coin" essentially steered me towards becoming a teacher, which I thank the Good Lord for.  Teaching History is paramount in my mind for people - and not just kids.  History is part of the Humanities and the Humanities teach all of us about what life is, how we came to be, the joys of accomplishing goals and the heartaches of life-changing failures.  It connects us to the institutions around us and quite simply, explains virtually all issues that are prevalent today.  In short, we live in the present, strive for a better future but require an under-standing of the past to be successful.  This is the mindset that I bring to my class and hope students will understand these connections. 

I know that students have  different needs in understanding information so I try my best to differentiate instruction as much as possible.  Still, in a rapidly competitive world, basics in soft skills like reading and writing are more important than ever and therefore I stress these in my class. 

I am on the Pastoral and Finance Councils at my home parish, Good Shepherd in Menomonee Falls where I am also a Eucharist Minister and catechist.  My faith is very important to me and I have no doubt that God has led me to the benefits I enjoy in life today.  My faith as a Catholic is diverse but my connection to the Principles Of Catholic Social Teachings are at the forefront of my faith since they give everyone a blueprint on how to live and what is important.

I have been teaching since 1997 and have a Bachelor's Degree in Education with a Social Studies and History Emphasis.  I also have a Master's Degree In History.  I put my faith in The Lord and trust that He will continue steering my life!

I graduated from UW-LaCrosse with a degree in Physical Education. I have taught on and off in the Archdiocese of Milwaukee and with the Greater Milwaukee Catholic Home Educators Organization. I love my faith and I love to be active. These two forums have given me the opportunity to share my love for both!

Being a parishioner at St. John the Evangelist allows me to share my faith with my students at Mass. I also have come to know and love the sense of family that this school and parish offer.

I believe that we can only be our best when we are spiritually, emotionally, physically and intellectually 'fit'. I use my time with my students to promote these four areas because they are so intermingled. I promote accountability for oneself, working hard to achieve their highest potential and quality of work over quantity. I hope to instill a desire and confidence to be active for a lifetime.

I feel very blessed and honored to work with you in helping these students to be the best that they can be.

I believe that music is in everyone!  I love helping children find their singing voice through songs and games.  We learn to sing in-tune, clap rhythms, and move to a steady beat.  We then learn to read/write rhythm and melody notes, recognizing what we hear in music and creating our own songs.  Our music activities include singing games, dancing, drumming, and listening.  It is an absolute joy for me to make music with the children of all ages.

For over 16 years I taught full-time in K-8 public schools.  While teaching, I earned my Masters in Music Education at Silver Lake College.  Then I was gifted with twin girls and I decided to work part time.  I am a music instructor for Wisconsin Conservatory of Music in their Community Connections and Early Childhood Music programs, as well as a private piano teacher.  I am also an active member of St Stephen Catholic Church in Oak Creek.  As my children are now in school, I am very excited to work both at the Conservatory and at St. John the Evangelist.  It means a great deal to me that I may share my gift of music and my love of the Catholic faith with my students.  St Augustine said, "When you sing, you pray twice."

I feel blessed to be part of the SJE school community! I have known I was going to be a teacher since I was a young child. Teaching is truly a calling. St. John the Evangelist embodies a school environment that allows me to help my students flourish to their full potential. My number one goal as an educator is to motivate my students to succeed! When intrinsic motivation is combined with students having the skills needed to be successful in school, there is no stopping them! 

I have been teaching since 2003. My experience lies mostly with middle school students. A few years ago, I decided to put my masters degree in educational policy and leadership to use. I have been working with new and struggling teachers as an instructional coach around the Milwaukee area. I have also been teaching aspiring teachers at the University of Wisconsin Milwaukee. Although these experiences have been wonderful, I really missed working with children. Being the resource teacher at St. John the Evangelist allows me to work with kids again, which is my passion. I would like to give a big thank you to all of you parents for sharing your wonderful children with me!

¡HOLA!  Me llamo Señora Fiedler.  After spending several years as a stay-at-home mom to my three children, I am thrilled to return to my previous career as a Spanish teacher.  As a resident of Greenfield, I live only a few minutes away from SJE, and I have enjoyed becoming a part of this tight-knit school community.     

SJE contracts with my employer, Futura Language Professionals, to provide a Spanish program for grades K5-8.  Futura strives to create a positive, welcoming language-learning environment.  Spanish is taught through games, songs, and hands-on activities.  Cultural topics are integrated into language instruction.  Academic rigor increases gradually in age-appropriate ways.  My primary goal is that your children LOVE Spanish and become life-long Spanish learners.       

I hold a bachelor’s degree in Spanish Education and Teaching English to Speakers of Other Languages from UW-Eau Claire and a master’s degree in Education from UW-Stout.  I studied abroad in Valladolid, Spain, and I have traveled throughout Spain and Mexico.  I have taught middle and high school Spanish (Levels 1-5) in the Madison and Minneapolis metro areas.  

In my spare time, I love to go camping with my family, especially at Peninsula State Park in Door County.  I enjoy drawing, crafting, and cake decorating.  Music is very important to me, and I have played in the handbell choir at my church for many years.  

I hope that students of all ages will be excited to share with you what they are learning in la clase de español!
