The journey starts as students take the 8th-grade placement test, and it culminates four-and-a half years later when the students walk across the stage at graduation.


The Office of Guidance and Counseling provides an array of services, ranging from academic and college counseling,  alcohol and drug prevention to personal counseling.

Services include academic assessment, academic advising, course selection and registration, college advising and recommendation letters, suicide prevention, personal counseling, dual credit advising, NCAA Clearinghouse advising, credit remediation, CACC liaison, freshman focus, high school transcripts, and coordination of college representatives.


Our team of professionals is knowledgeable, experienced, and very willing to assist students and parents as they navigate through the four years of high school with a view toward college and beyond.

It has been our tradition that our guidance counselors remain with our students throughout their four years to ensure a personal and familiar connection with each individual student and his/her family.

Our staff is here to answer questions, intervene in difficult situations and provide assistance during your student's high school years.
