St. Gregory Faculty & Staff

I am humbled and excited to be entering this academic year as your principal. I have been a part of the St. Gregory School community since 2008 and a life-long member of the Zelienople- Harmony area. St. Gregory School and Divine Grace Parish are truly home to me and my family. I am keenly aware of what a special place this school is and the impact it can have on our children and their hearts. I welcome this opportunity to lead a school as profoundly rooted in faith and quality academics as St. Gregory School. I believe in fostering a learning environment where the teachings of Christ are not only taught but lived.

I have been in the field of education for the better part of over thirty years, with knowledge of both the public and Catholic schools. I will bring my experiences as parent, teacher and school director to the role. I will use these various perspectives to assure that as a school community, we are working toward the shared mission of academic and spiritual growth for our children, families, and staff.

Let me assure you that your St. Gregory School faculty is deeply committed to helping your child(ren) grow and succeed. They boldly model and proclaim the love, ways and truths of Jesus Christ. It will be our mission to fiercely guard and nurture your child’s mind, body, and soul. The teachers and staff have been actively preparing for the year ahead and we can’t wait to hear the sounds of the children in the hallways again.

I encourage you to be an active participant in your child’s educational and spiritual journey. (You can start by joining the PTG at Tuesday’s pool party and school orientation on Wednesday evening.) I also want to emphasize that your role is an important one as we build a supportive partnership between home and school. This will be integral in fostering your young ones’ development and will empower him/her to reach their full potential.

I may be a familiar face to many of you and a new one to others. Either way, I look forward to welcoming you and your children to the upcoming school year. I have a deep love for this school community and my Catholic faith, and I could not be more excited for the year that lies ahead of our most precious young souls!

In closing, please pray for me, the staff, our clergy, and the entire school body as we enter this new school year. May the Holy Spirit and the love of our Blessed Mother be present within our building and our hearts each and every day.

Yours in Christ,
Michelle O’Shea

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 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.
