Tressa AndrewsTressa Andrews
School Director
Nature-Based Science Teacher in our Outdoor Classroom

I am from Harford County and hold a B.A. in Early and Elementary Education from Notre Dame of Maryland University. I have 20 years’ experience in education, 15 of those years in Pre-K! This past year I became certified as a Nature-based and Forest Teacher. Last year I was the Interim Director during our return for in person learning during COVID. This year I am honored to be the Director and be the Nature-Based Science Teacher in our New Outdoor Classroom. It is essential that our youngest learners begin their educational journey loving nature and protecting their future environment.

Family is an important part of my life. I have a daughter Sara who is a graduate of Hollins University in Roanoke, VA, and a published author. I have a dog named Charlie who I love very much! I have a father who was also a teacher for many years, two older sisters, and four nieces. I enjoy photography, painting, and everything about nature. I love my Ravens and my O’s!

I also support the Special Olympics by being a Super Plunger for the past six years. This event involves plunging into the cold waters of the Chesapeake Bay at the end of January 24 times in 24 hrs. It is a challenge, but the Special Olympians inspire me to be as brave as they are when they compete. As a super plunger we are also dedicated to raising awareness and financial support to aide all those with intellectual and physical disabilities, so they have the same opportunities to compete in sports and leadership experiences.

I chose to become a teacher because my very first teachers, my mom and dad, encouraged me to be curious, ask questions, and to love learning. They instilled the importance of community and giving back to others.

I am looking forward to another year working with the families of Trinity Preschool and watching our youngest learners blossom throughout the school year and gaining a solid foundation not just in education, but in being a good neighbor and a kind human being.

I am the proud mother and wife and have been married for seven years to my wonderful husband David. We have a daughter Averie who is five years old and goes to Trinity. I’m also a mom to our fur baby Rottweiler Bella. My hobbies are being a dance mom and watching comedy movies with my husband. My family means everything to me.

Lora RobertsonLora Robertson
Two-year-old Teacher

My name is Lora Robertson, but my students refer to me as Ms. Lorraine. I was born in Greenville North Carolina for a short time and then my family moved to Baltimore where I was raised throughout my childhood. I graduated from high school and continued my education at BCCC.

I have been a teacher at Trinity for 20 years and love everything about helping shape young children. Teaching young children is my calling and my hope is to continue teaching for many years.

Susan O’NeillSusan O’Neill
Two-Year-Old Assistant Teacher

My name is Susan O’Neill, originally from Rochester NY. I moved to Syracuse, NY to teach school and eventually stayed there after I married to continue teaching and raise my family.

I have 3 children. Kristen my oldest is a Special Education teacher in Syracuse, my middle child Megan teaches preschool at a Montessori school in Denver, Co., and my son Tom works and lives in Hendon, Va.

I went to college in Missouri and did my graduate work at The University of Rochester and Oswego state in New York. After graduating from school, I taught second grade in the city of Syracuse and after the birth of my third child I owned and operated a preschool in Syracuse with another certified preschool teacher.

I returned to teaching after my son was in fourth grade, I based a lot of my teaching on children’s literature. An example is using James and the Giant Peach written by Ronald Dahl. I based all my lessons in Reading, Writing, Math, and Science on this fabulous book. It is enriching to using literature across the various subjects.

I moved to Towson, Maryland to be closer to my son Tom and have grown to love this area.

My interests are reading, cooking, and traveling. You could say teaching is in my blood as my mother taught for 30 years in Rochester, NY and my daughters and I are teachers as well.

I am so happy to be a part of the Trinity preschool family. I live close by the school and I volunteer at the Surprise Shop. Towson is a great fit for me, and the best part is that I love my job working with the two-year-old students at Trinity.

I have three boys of my own and they have all been a part of the Trinity family as well. Justin (23), Sam (21), and Joseph (10). As a parent I can honestly say that Trinity Preschool had given my children a wonderful start towards their academic successes. They also became more independent, social, and confident. My class is more than just my class for the year. I love to take them under my wing and help them achieve goals and milestones as though they were my own.
