Mrs. Maureen Houlihan
Mrs. Maureen Houlihan Biography
I have had a long and varied career in teaching that began when I graduated from Slippery Rock University with a BS in Special and Elementary Education. My first 12 years of teaching were in special education with Beaver Valley Intermediate Unit at New Horizon School. After taking a break to spend time at home with my three children, I was called back to teaching at St. Gregory School, and am now into my 26th year. I have had the privilege to teach at many levels over the years, but I have primarily taught Language Arts, Social Studies and academic support.
My husband Dan and I have three grown children (who are all graduates of St. Gregory) and are blessed with two grandchildren with hopefully more to come! First and foremost, we wanted our own children to experience a faith based education which they certainly received, but in addition, their academic education was also superior thanks to St. Gregory School. Today, I still observe the same quality of faith and academics being taught that will lead our children into a bright future.

Mrs. Cindy Haney Biography
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.

Ms. Alyssa Kulmoski Biography
My name is Alyssa Kulmoski and I am looking forward to the beginning of a new school year. I am especially excited for this year because I am joining the St. Gregory community! I will be teaching second grade and am eager to assist my students in growing both spiritually and academically. I have much in common with these children for I attended Catholic school as well. I grew up in Wexford and went to St. Teresa of Avila for grade school and Oakland Catholic for high school. For college, I moved to Baltimore to attend Loyola University Maryland, a Jesuit institution, where I studied elementary education and special education. I graduated with a stronger faith and broader knowledge base leaving me enthusiastic to shape the minds of the youth. I chose to remain in Baltimore for one year to teach fifth grade math, social studies and science. I finally decided to move back home to Pittsburgh and was ecstatic to accept the second-grade position at St. Gregory School. Second grade is an important year for the Sacraments and I am ready to share my faith and love for God with these children. I am looking forward to meeting my students and their families and growing in faith in the wonderful St. Gregory community, which has already made me feel welcomed and loved.

Ms. Erika Barlow
Grade 6-8 Social Studies, Grade 4 & 7 Religion
Ms. Erika Barlow Biography
This is my third year teaching middle level social studies. I earned a Bachelor of Science Degree for Social Studies Education at Indiana University of Pennsylvania in May 2014.
I am proud to say I am a former St. Gregory Catholic School student. I attended this school for the full nine years and then went on to Freedom Area High School. I credit this amazing institution for giving me the tools to excel academically, as well as the Christian morals to follow in the footsteps of our Lord Jesus Christ. I am eager to work alongside some of the best and most dedicated educators in the state. I can say that with deep sincerity because many of my colleagues were my former teachers. These exceptional teachers can be credited with opening my eyes to the power of knowledge and my heart to the power of the Lord. I cannot wait to do the same now for your child.
I not only plan on modeling how to be a good Christian, but also instilling the skills and knowledge to be a productive citizen. I believe that every student can learn if they are given the appropriate tools and resources. I have found through implementation and practice that student centered learning is effective in allowing students to grow in their knowledge and reach new heights of content mastery. Students will be given ample opportunity to use technology both appropriately and wisely in the classroom, as well as opportunities to develop other 21st century skills needed to be successful in this technological age. Please feel free to contact me now and in the future with any questions or concerns. My family and I are still parishioners of this beautiful church and I look forward to seeing many of my students and their parents at church.
Let’s have a great year!
Sra. Susana Garcia
Spanish & Music
Sra. Susana Garcia Biography
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.
