Amy Schlegel, Principal
I am honored to serve as the proud principal of St. Gregory the Great Parish School. I entered into my fourth year at St. Greg’s and am grateful to work with an amazing faculty and staff who dedicate themselves to our mission every day. I attended Mount Mary University for both my undergrad and graduate studies and completed my administrative certification at Concordia University. My husband Jim and I have an 19 year old son who is in the U.S. Marines, and a 16 year old daughter who is a junior at DSHA. I have over 25 years of experience working in Catholic schools in the Archdiocese of Milwaukee and continue to build upon my strong faith in Catholic education. My personal mission is to motivate, educate, and inspire others to be their best. I am so happy to be a part of the St. Greg’s community.
Sherry Fritz, Administrative Assistant
Hi my name is Sherry Fritz. I am blessed and grateful to be part of St. Gregory the Great Parish School. In 2002 I was hired as the Parish Secretary after 25 years in the travel business. I enjoyed my job as Parish Secretary and loved meeting and interacting with all of the wonderful parishioners. In the summer of 2003, Fr. Ken Omernick asked me to take the secretary position at the school. I was so excited I practically flew across his desk and accepted! I have never regretted that decision. While my job has changed over the years and I am now the Administrative Assistant, I still enjoy coming to school every day. I love interacting with all of the students and families. One of my favorite things to do is to give tours of our wonderful school to prospective families. I get the opportunity to know them and show off our school and parish community.
My husband Bill and I have two wonderful daughters, Amy and Noelle. We love spending time with our granddaughter, Elena as well as family weekends at our trailer in Waupaca. In my spare time I love to bake, read, sew and scrapbook.
I am always excited to begin a new school year at St. Greg’s and look forward to getting to know our new families better and to see how much the kids have changed and grown over the summer!

This is my 23rd year teaching at St. Greg’s! I love watching the sparkle in children’s eyes when they have discovered something new! I feel blessed not only to work with your children at school, but to take an active role in the faith community my family belongs to also.
When my schoolwork is done, I make time to cook and bake, read, and do counted cross-stitch. I enjoy time spent with family, friends, and travel – both near and far! Weekends can find us driving to Madison for sporting events or to visit our son who is currently attending pharmacy school there.
Mary Jablonowski, Grade 4 Instructional Aide
I am Mary Jablonowski. This is my sixth year as a member of the St. Gregory the Great staff. I am very happy to be the fourth grade instructional aide this year. I received my Bachelor of Arts degree from Marquette University where I majored in elementary education and Spanish.
I enjoy helping students develop various learning styles which will enable them to become more independent workers. I look forward to collaborating with the classroom teacher to provide a positive, faith-filled year of academic, spiritual, and social growth. I am especially excited to help the students become more proficient in reading, math, spelling, and writing as they learn to work individually, in groups, and as a class.
Prior to working at St. Gregory the Great, I taught primary grades in the Milwaukee archdiocese for 17 years.
My husband, Tom, and I chose Catholic education for our children from elementary school through high school. Two of our children also graduated from Catholic universities.

Over the past 22 years, I have had the pleasure of teaching third grade and fifth grade. Fifth grade is a very exciting year of learning, growing, and sharing our faith in Christ. I want all of my students to know that our classroom is a very loving and nurturing environment in which they can grow and become independent problem solvers. In order to become independent problem solvers, my students know that it is OK to make mistakes because that helps us to look at problems in different ways in order to determine a solution. I am a firm believer that communication is an important part of student success, and I look forward to getting to know all of my students and their families.

NASCAR is my favorite sport and Matt Kenseth is still my favorite driver. I do, however, follow football, baseball, basketball, and I’m especially interested in our school’s teams. See you at the games?

Amy Wabiszewski, Reading Specialist
Hello! My name is Amy Wabiszewski. I am excited to start my second year at St. Greg’s. This is my 9th year of teaching in both private and public schools throughout Milwaukee. I have taught 1st grade, in a 3rd/4th split classroom, and served as a Title1 intervention teacher for kindergarten through eighth grade students. I graduated from Cardinal Stritch University twice, once with my Elementary Education degree and again in December 2015 with a Masters in Language and Literacy and a Reading Specialist license.
I have been married for seven years, have a daughter who is almost 3 and a son who was born in January. I believe reading is a community effort. It takes all the people involved in a child’s life to help them become a successful reader. I am thrilled to be another one of those people for the students of St. Greg’s and look forward to fostering a love of reading in all students!

My name is Alice Erlandson, and I am delighted to again be part of the staff at St. Gregory the Great Parish School. I graduated from Michigan State University in 1983 with a BA in Education and taught for the next 20 years. My husband and I joined the parish in 1988 and later that same year I was hired as one of St. Greg’s sixth grade teachers. I earned my Masters of Education in 1996 from Cardinal Stritch University and continued to teach full time through the 2002-2003 school year when I decided to take some time off to raise our daughters. In 2009 I returned to St. Greg’s as an instructional aide and had the opportunity to work with some wonderful teachers. In 2015 I became the director of Bookends, St. Greg’s before- and after-school program.
My husband and I are both from Michigan, so St. Greg’s has been our family and is family to our children as well. All three of our daughters attended and graduated from St. Greg’s. We have all enjoyed the many different opportunities available to our family through the school and parish, and we cherish the lifelong friendships we have made here.
I have enjoyed many roles at St. Greg’s, including sixth grade classroom teacher, parent volunteer, school committee member, Girl Scout leader and coordinator, substitute teacher, instructional aide, and Bookends director. I love that I have made so many connections with parents and students over the years. One thing that brings particular delight is to run into my former students at church, the Festival, around town or even bringing their children to attend St. Greg’s. I love to hear what they have been doing since we last saw one another and to reminisce about Africa projects, read alouds, and prepositions!
