Tara grew up in Montreal, Quebec, Canada, and benefitted from the provincially mandated bilingual education system. She and her family are all avid equestrians, having discovered Aiken as a perfect winter training base in 1977. Married for 29 years to polo player Charlie Bostwick, Tara, Charlie, and their family have made Aiken their full-time home since 1994. 
Tara has traveled extensively throughout her life, most recently to Central America as chaperone to youth groups.

Tara’s educational philosophy incorporates her desire to provide students with a relevant global education. 

“Young people must develop a strong awareness of the world around them. Today they need to have the tools to navigate a global community that is more interconnected than ever before.  It is our role as educators to provide a twenty-first century curriculum that not only addresses the divergent learning styles of our students but also provides a course of study that tackles the challenges which the next generation of leaders will face.”

Hilary started her teaching career in the North Carolina public school system, where she taught for 13 years. After relocating to Aiken Hilary found herself at Aiken Preparatory School teaching pre-algebra and learning strategies. She remained through the transition and taught at Mead Hall Episcopal School for the last 5 years. We are so fortunate to have Hilary on staff. She will head up our Learning Strategies Department, bringing experience, enthusiasm, and compassion.

 John hails from the coal mining hills of Kentucky where his father  taught the importance of hard work and humility. He began his teaching career here in Aiken at AHS where he taught math for 6 years and coached football. He then became Assistant Principal at Harden County High School in Savannah, Tennessee. While there he also taught Algebra I and II. Returning to Aiken John went to work at the then recently built SAHS teaching math and coaching football. In 2000 he became head of the math department until his retirement in 2010. During that time he became head coach of South Aiken's Football program leading the team for 3 years and producing a number of successful collegiate players.


John has an innate ability to make all of his students at ease by finding amusing  anecdotes to the math lesson at hand. His jovial disposition makes him  immensely popular with our students. He views math as a challenge to be solved always making sure that his student understands how to not only work the equation independently, but to understand how to apply that knowledge to similar problems. He is a master of demystifying math. 


When not tutoring John loves gardening at home, woodworking, spending time with his grandson and traveling with his wife. 




I grew up, went to college, and taught math for 17 years in Romania, in a beautiful medieval city in Transylvania. Together with my husband and two daughters, we moved to Aiken in 2002, and continued our teaching careers in South Carolina. I taught entry level Statistics classes during my master’s program at USC Columbia, but for most of these years I was a Math teacher at South Aiken High School.

My experience ranges from middle school to college level Math, and over the years I taught students with various difficulties, skill levels and abilities.

 I am passionate about teaching math, and strongly believe that with a combined effort, every student can make progress, and I dare say maybe even start to enjoy it in the process.

When I need to unwind, I love to hike, practice yoga, and play pickle ball. I am excited to join this wonderful team of educators and am looking forward to working with you.
