St. Gregory Faculty & Staff

I am honored and excited to join St. Gregory School as the interim principal. As an experienced educator and advocate for holistic student development, I am deeply committed to fostering a vibrant, faith- centered community of learners dedicated to academic excellence and personal spiritual growth.

My academic journey reflects my passion as a lifelong learner. I earned a bachelor’s degree in Early Childhood, Elementary, and Special Education from Slippery Rock University, two master’s degrees from Duquesne University in Educational Leadership and Curriculum and Instruction, and a doctorate in Educational Leadership, Administration, and Policy Studies from the University of Pittsburgh.

These experiences have shaped my understanding of the transformative power of education and prepared me to lead with vision and purpose. I have dedicated 15 years to education as both a teacher and administrator in Catholic, private, and public schools. During that time, I developed district-wide programs focused on student and staff well-being, designed academic summer camps and after-school STEM and intramural athletics programs, and implemented safety and security trainings, policies, and procedures. I have had the opportunity to work closely with executive boards and central offices to advocate for faculty and students, draft strategic proposals, negotiate budgets, and introduce innovative solutions to increase enrollment and add new revenue streams.

In addition to my extensive background in education, I have been fortunate to gain valuable experience in the corporate sector. Most recently, I served as Director of University Relations at Finch AI, where I built meaningful partnerships with colleges and universities and worked to expand student opportunities through robust internship programs for both undergraduate and graduate level students. Before that, I was a Senior Marketing Manager for Amazon, leading the Public Sector team and managing over 100 large scale global events. These roles enhanced my ability to leverage technology in the education space at all levels of learning. I worked closely with c-suite leadership teams to execute complex initiatives, adhere to deadlines, foster collaboration, and drive results with forward thinking marketing and event strategies and initiatives. Faith and family are central to who I am. My husband and I live in Butler, where we have raised two daughters. Our oldest, lives in Florida, pursuing a career in baking and pastry and our youngest is an active 8th grader involved in competitive gymnastics, cheerleading, and track. As a family, we enjoy spending time outdoors with friends. Camping, boating, jet skiing, traveling and the beach are just a few of our favorites. I believe each of us are tasked with a responsibility to foster a faith filled life for ourselves but also all of those whom we are entrusted to care for. We must always remember to “Keep Moving Forward, God Will Show Us The Way”.

It is a privilege to step into this role and contribute to the strong foundation of faith and excellence that defines St. Gregory School. I look forward to working closely with families, faculty, and staff to nurture the spiritual, academic, and personal growth of each student. Together, we will continue to build a community of learners united in purpose and guided by our shared values.

I have been working in the school office since 1991. What started out as a job, has become so much more. I feel so very blessed to be a part of the amazing

St. Gregory family. I have seen so many students enter our school as young children, and grow into mature, educated and faith filled young adults ready to spread their wings! It makes me so proud when I run into a former student and they still run over to say “hello” and tell me what they are up to in high school, college or in their career.

I now how two children of my own who attend St. Gregory School. I am so glad that they have to opportunity to experience school in such a loving, faith filled atmosphere.

This is my 14th year working at St. Gregory School. My days are shared between the school office and library and this is where I have an advantage. In addition to getting to know our families through the office I get to spend time each week with Kindergarten through 6th grade during their library class each week. I especially enjoy reading to the younger students each week and sharing that time with them.

It is wonderful to see the growth in St. Gregory School as I and both of my children are graduates. The school continues to offer a quality academic and Catholic education in a warm, family environment.

Hello, my name is Christine FitzGerald. I am thrilled to be the preschool teacher here at St. Gregory School! My family and I relocated to this area 5 years ago and I have been active in the St. Gregory community by volunteering in the preschool classroom, teaching religious education and helping with the vacation bible school program.

I graduated from Carlow University with a degree in Elementary Education, and received my Masters Degree in Special Education from Niagara University. I have many years of teaching experience working with young children in elementary and early childhood education classrooms.

I grew up with a strong Catholic background and see the importance of introducing faith to our children at a young age. Children are never too young to learn, and with the right encouragement, their learning is limitless! Having had both of my children go through this program, I saw first-hand the enjoyment of installing the Catholic faith at a young age. I am excited to now be teaching and creating that enjoyment for our young children!

My name is Marianne McElree and I am the kindergarten teacher. I have the privilege to teach at St. Gregory’s School. I have been teaching Kindergarten for 11 years. I attended Duquesne University and graduated with a Bachelor of Science degree in Elementary Education K-8. I also am certified to teach mid-level English. When I am not at school, I enjoy spending time with my family, reading, and playing tennis.

My name is Kris Tkatch. This is my fourth year as the 3rd grade teacher at St. Gregory's. I attended Catholic schools myself from grades 1-12, so I know the importance of the Catholic education that St. Gregory School provides to our students and the community. I started my teaching profession at a Catholic school, Mount Gallitzin Academy, in Baden, Pennsylvania, where I taught 5th grade. Before joining the St. Gregory faculty, I had been working in the Ambridge Area School District doing Title I reading and math support. I wanted to have my own homeroom again, and this is what brought me to St. Gregory's!

On a personal note, I live in Cranberry Township with my husband and three wonderful sons (ages 17, 15, and 12). I am a member of St. Ferdinand's Parish and taught 4th grade CCD there for many years. I received my Bachelors of Science in Education from Kent State University and worked on my reading specialist certificate at Slippery Rock University.

My name is Mrs. Dunn and I’ve been teaching at St. Gregory School since 2017. I currently teach 4th Grade ELA and 5th Grade Math. Before teaching here, I taught the Kindergarten Readiness Program for three years at St. Mary School in Glenshaw, PA. I earned my Bachelor's Degree in Elementary Education and Special Education from La Roche College in 2014. I earned my Master's Degree in Reading Specialist and Instructional Coaching in December 2017.

My name is Libby Schultz and I have been teaching at St. Gregory School since 2000. I teach 5th grade, science and health to 4th grade, and computers to 2nd through 4th grade. Prior to St. Gregory school I taught at St. Alphonsus and Mars School District. St. Gregory is a family atmosphere where everyone looks out for each other, and where everyone cares for one another. We really are one big family. I truly am blessed to be teaching at such a wonderful school.

My name is Maureen Kelly and I have been at St. Gregory’s since 1998. I taught 4th grade for 12 years and am now the 6th grade teacher. I teach 6th grade language arts and religion, 5th grade social studies and religion, and 4th grade social studies. I have 3 children, two of which attend our school. I love the family atmosphere we have here!

I am incredibly excited to begin the school year at St. Gregory's and be your middle school science teacher! I want to take this opportunity to give you a little background about myself. I graduated from Penn State, where I earned a Bachelor’s degree in Elementary Education and a minor in Special Education and then a Master’s degree in Learning, Design, & Technology! I also have certifications for Middle School Mathematics and Science. Life long learning is a goal I hope to continue to pursue!

Before coming to St. Greg's I taught 4-8th grade math and science at St. Wendelin School. I also have held long-term substitute positions at North Allegheny, Hampton, and Ellwood City school districts teaching primarily in grades 4-8.

I was born and raised in Mexico City, where I got my bachelor’s degree in Marketing and Advertising. After working several years in advertising agencies, television companies and newspapers, my husband got transferred by DIRECTV Latin America to Brazil, so I quit my job in 2000 and off we went. We lived in Brazil for a full year.

In 2001 we were sent to Argentina, Venezuela and Puerto Rico. Finally in 2002 we settled in Miami, FL. Two months before my daughter was born in 2006, my husband got a job offer from a company in Pittsburgh. All we knew about Pitt was ”Los Acereros” (the Steelers). It’s important to mention that “American Football” is big in Mexico, especially in Mexico City, where, since the 1970’s, the Dallas Cowboys, and the Pittsburgh Steelers are huuuuge. (My dad was a Chicago Bear, though, who knows why...but we liked Los Acereros). Anyway, we knew that the city where the Steelers were born could be nothing but awesome! We finally moved when my daughter was 2 months old and immediately fell in love with the city and the people.

Seriously, the people in this area are the nicest, friendliest, kindest people in the Country (at least in all the cities I have been). Being a traditional Catholic family from Mexico, we decided this was the perfect place to raise our family, so we settled. After being a stay-at-home mom for 3 years, I decided I wanted to work again, but not the crazy hours my career would demand. I wanted to do something where I could still be with my baby. I’ve always loved being around kids and have a very good knowledge of the Spanish language (comes with the advertising part of my degree), so I began tutoring at home. A few months later I got an offer from Little Linguists to teach an after school program in different Elementary Schools from the area. I worked for them for 2 years when I got an offer from 2 preschools to be the Spanish and Music teacher (music has been part of my life since I was born, but that’s another story that I will tell some other time).

Some people asked why preschool? Aren’t they too little? They barely speak English, etc. I will always answer that it’s the best time to learn anything, absolutely anything.

Finally, after another couple of years teaching the little ones I got the best job ever: Spanish teacher at St. Gregory Elementary School. This is my 4th year here, and let me tell you that it wasn’t until I began working at St. Greg’s that I realized teaching was my calling. I come to work with a big smile and leave with an even bigger one. I am so blessed.

My name is Rachel Sposito and I have been teaching at St. Gregory School for 10 years. I currently teach Physical Education to grades 1st through 8th. I graduated from St. Vincent College with a Bachelor of Arts Degree in Psychology. I have a teaching degree in Early Childhood and Elementary Education.

I live in Evans City with my husband, Bob, and two children, Gianna and Nico. I love teaching at St. Gregory! It is such a wonderful environment. I hope to teach students activities and skills that they can use throughout a lifetime.
