Meet the Director

Diane Sartor If Diane Sartor could be summed up in one word, “passion” would be the best candidate. Energetic and driven, Diane has a tremendous enthusiasm for language, teaching, and life, a passion which she has channeled into her more than 25 years of mentoring students at ACI Institute. “Today’s students are challenged to learn faster and absorb vast amounts of information to keep up with the demands of our rapidly changing world. As educators, we have a responsibility to guide our students to embrace challenge, create reachable goals, and provide them with the skills they need to succeed, not just on their road to college, but in life as well.”
