Carlos Casilla-Nova

He directs Eightnotes (our Upper School auditioned soprano and alto a cappella group) and Middle School Chorus, and he is also the music director for our fall musical production.
Carlos came to Park from the Shipley School in Bryn Mawr, Pa., where he served as the Pre-K-12 Performing Arts Department Chair, and the Director of Choirs, teaching 4th through 12th Grade choirs. In his role as the Pre-K-12 Department Chair, Carlos worked closely with the Upper School administration on student sectioning, faculty evaluations, and scope and sequence of the Performing Arts curriculum. Carlos is also the Artistic Director and Senior Honors Choir Conductor for the York County Honors Choirs in York, Pa., supporting and leading singers in the York county district.
In 2022, Carlos received the Outstanding Young Conductor Award by the Pennsylvania chapter of the American Choral Directors Association. He holds a Bachelor of Music with a concentration in Piano and Vocal Performance from William Carey University and Master of Music with a concentration in Choral Conducting from Louisiana State University.
“I was born and grew up in the Dominican Republic, and it was there that I fell in love with conducting. I worked as rehearsal conductor for a few productions that were presented at the National Theater in Santo Domingo, DR. In my undergrad, I became the first undergraduate student to conduct the orchestra for an opera production (The Magic Flute.)”
Maggie Baker
Maggie is a third grade homeroom teacher. She teaches math, reading, and writing, placing a particular emphasis on social-emotional learning in her classroom. She also works with the other members of the third grade teaching team to update and plan their theme study, which focuses on the Early People of Maryland.
Before coming to Park, Maggie was the Assistant Head of School for a small progressive school in Chicago for four years, serving both as an administrator and part-time teacher for Grades K-5. She worked in non-traditional forms of education, including for theaters, science centers, and museums, for many years before returning to school and pursuing her master’s in elementary education from DePaul University. She has a B.A. in anthropology with a minor in Spanish and GIS, also from DePaul University.
“I love sewing and crafting. I have a pet cat named Ophelia. I recently moved to Baltimore (in 2022) and am enjoying exploring the city!”
Carla Guarraia
Carla is the chair of the Upper School science department. She is an advisor to the Beekeeping Club, the International Student-led Arctic Monitoring and Research (ISAMR) program, and the Hiking and Camping Club, and develops Wellness programming.
After earning her Ph.D. in molecular biology and conducting research in chemical and biological engineering, Carla did a brief stint in industry studying nanoparticles for drug delivery. She then turned to teaching, following in her husband’s footsteps, and worked at St. Paul’s School for Girls. After visiting a beekeeping club event at Park, Carla decided she wanted to work here. “Now, I’m the best version of myself, doing research and developing programs that I believe in, supporting students and seeing how their unique experiences can lead to innovative changes that make our world a better place.”
In January 2025, Carla received the Presidential Award for Excellence in Mathematics and Science Teaching. The award is the highest recognition that a Kindergarten through Grade 12 science, technology, engineering, or mathematics teacher may receive for outstanding teaching in the United States. Only one teacher per state is recognized each year, making Carla the only teacher selected in all of Maryland — an extremely competitive region.
Carla loves working on her mini-farm raising chickens, turkeys, bees and composting to restore damaged soils, but admits that she’s “not so good at raising vegetables.” She also likes more traditional activities, including watching Netflix, doing crafts with friends, and reading middle school fiction.
Carla has a B.S. in Biology/Chemistry Interdisciplinary Studies from Loyola University in Maryland, and a Ph.D. in Molecular and Cellular Biology from the University of Maryland, Baltimore County. She was a Postdoctoral Research Associate in Chemical and Biochemical Engineering at University of Maryland Baltimore County. She is the parent of a Park School student in the Class of 2028.

After college, Sam worked as a staff writer for a small Ohio newspaper. He then returned to Maryland and began his teaching career at the Queen Anne School in Prince George’s County. He taught English and math to middle and high school students, and coached basketball and baseball. Sam then moved to Jemicy’s Upper School and was there for 11 years, teaching English and involving himself in many opportunities. “I served as the English department chair for more than eight years; I coached varsity men’s basketball (earning the school its first MIAA wins), and served as an assistant coach for the men’s soccer team; I directed and supervised student-written theater productions; I inaugurated a school literary magazine, a school newspaper, and an independent study program for the humanities.”

With the help of the faculty, families, and students, Tyler founded the Diversity, Equity, and Inclusion program at the school. He has experience working with constituent groups to create spaces that support individual members, while confronting issues that impede building a more inclusive community. In all of his teaching and coaching positions, Tyler makes it his top priority to ensure his students and families feel seen and empowered.
In the summers, Tyler runs a week-long summer camp that is centered around getting kids outside and growing their confidence and interpersonal relationship skills.
Tyler holds a B.S. in Natural Resource Conservation from the University of Massachusetts Amherst, and a Massachusetts Initial Licensure in Middle School Science from Shady Hill Teacher Training Center (TTC), where he was a Grade K-VIII apprentice.
