Why Karen loves teaching:
I will never forget 9th grade biology, when I was introduced to photosynthesis, Mendelian genetics, and the theory of evolution, a subject that I have lived and breathed ever since.  I remember staying after high school several days a week to ask my biology teacher questions and discuss biological concepts with her as if they were the most fascinating topics. I find the high school environment and unique student-teacher interaction to be an astounding opportunity.  It is an environment, which is constantly changing and developing, a place where minds are inspired and lives are changed.  I like tutoring as it provides unique opportunities for teachers to meet the needs of the individual student.  It assures a thorough understanding of the material by the student and allows the teacher to help the student reach a deeper level of understanding of the topics.

An interesting fact about Karen:
I love being active, whether it is running, hiking, gardening, or even yard work, I just love spending time outside!
