In the fall of 2010 I began teaching Anatomy and Physiology at Trinity-Byrnes. The class is an elective honors-level lab science, with the majority of students being juniors and seniors. With the help of Dr. William Naso and through my connections with McLeod Health, I am able to take my students to surgical observations. This experience allows the students to witness anatomy and physiology firsthand! I love introducing interesting facts about and processes of the human body to students using anatomical models, medical worksheets, and dissections.

Why should a family send their student to TBCS?

Being a former parent of 9 years, and a faculty member for the past 6 years has given me a broad perspective on what TBCS has to offer. If you have a child who is academically oriented, TBCS has choices - from unique Honors level science courses to AP level classes in all subjects. If you have a child who loves the arts - we have it all - phenomenal art programs, music, drama and dance. TBCS also offers a huge variety of sports so if your child is interested in exploring something new, our school makes this opportunity happen . And the best part - your child can do it all here!!!!
