I earned a Master’s degree in Teaching from Bellarmine University and then went on to earn a Master’s degree in School Counseling from Xavier University. Before joining Pathfinder, I spent eight years in the classroom as a middle and high school teacher, three years as a school counselor, and 12 years as a district resource teacher focused on college and career readiness. As a Pathfinder eSchool teacher, it is easy to see one of the many benefits of working with students in an online environment - flexibility. Our online courses allow students to work at a time and place compatible with their learning needs while allowing them to personalize their education.

I earned a Bachelor of Science in Education from Indiana University and a Master of Science in Education from Indiana University Southeast.  My teaching career began as a high school science teacher in Frankfort, Kentucky and then progressed to Moore Traditional School in Louisville.  While teaching, I furthered my education and earned my Rank 1 and Administrative Certification. 

In 2009, I worked as Dean of Students and as a part-time eSchool English teacher and night instructor at the Jaeger site of Jefferson County High School.  During the fall of 2011, I joined the eSchool staff as a full-time Resource Teacher and am excited to teach students across the United States in an online learning environment.

In 1993, I earned a Bachelor of Science degree in Secondary English and Theatre Education from Indiana University.  Upon graduation, I taught middle school for one year.  However, I soon learned that my heart was definitely at the high school level.  Since 1993, I have had the opportunity to teach every grade/level of English (grades 6-12) to include AP Language and Composition and AP Literature and Composition. 

Additionally, I have earned a Master’s degree in Secondary Education with a focus in Curriculum and Instruction from Indiana University and a Rank 1 in School Library Science from Eastern Kentucky University.  I was very fortunate in that both of these programs involved online courses.  In fact, my entire Rank 1 program at EKU was online.  Little did I know that this would prepare me for one day being an online teacher!  As a former online student, I know the importance of building a close student-teacher relationship in order to ensure academic success in the virtual classroom.  I am a strong advocate for online learning and know it has the potential of serving the needs of many students.  Please know that I always welcome constructive feedback as I strive to improve our English courses and provide quality instruction to all students.

This is my twenty-first year of teaching. I earned a Bachelor of Arts from Georgetown College, a Master of Arts in Secondary Education with a focus on Mathematics, and a Rank I in Secondary Education from the University of the Cumberlands. I have taught middle school and high school, and it's my 6th year with JCPS e-school and look forward to many more.

I earned a Bachelor of Arts degree in Mathematics and a Master of Arts in Teaching for Secondary Mathematics from the University of Louisville. Go Cards! Before arriving at Pathfinder in the summer of 2022 I spent the previous 11 years teaching at the J. Graham Brown School. I am looking forward to working with our students and fellow colleagues to help make Pathfinder a model for all online education.

I am so excited to be a part of the Pathfinder School of Innovation eSchool team!  The 2023-2024 school year will be my 18th year in education.  I started my teaching career at Augusta Independent School and taught 8th grade math, Algebra 2, and Calculus.  Then I moved to Louisville, and spent the next 15 years at Eastern High School and Western Middle School for the Arts, where I taught Algebra 1 and  Geometry,  and then moved into a leadership role as a resource teacher and then Assistant Principal.  I earned my Bachelor’s degree from Centre College, my Master’s degree from Morehead State University, and my Rank One in Educational Leadership from Indiana University Southeast. I look forward to working with students in this asynchronous learning environment, where students are able to work at their own pace and access the content when convenient to them.

I earned my Bachelor of Science degree in Biochemistry and Molecular Biology from Bellarmine University. I went on to receive a Master of Science degree in Biochemistry and Molecular Biology from University of Louisville. During my time at the University of Louisville, I performed breast cancer research and received a fellowship from the Department of Defense. Upon graduation, I became an Adjunct Professor at Spalding University in the School of Natural Sciences. I eventually went back to Bellarmine University to earn a Masters of Arts in Teaching Degree and received state certification in High School Biology, High School Chemistry, and Middle School Science. I have been teaching for Jefferson County Public Schools since 2012. Before becoming a science resource teacher at eSchool, I taught chemistry and biology at Jeffersontown High School for 5 years. I am very excited to be on the eSchool staff and look forward to working with students in a different capacity. Online learning is becoming increasing popular and is an excellent way to allow students to earn high school credits in a non-traditional classroom environment.

I earned my Bachelor of Science degree in Zoology at the University of Kentucky.  During my time at the University of Kentucky, I cheered for men’s football and basketball, and competed on the National Champion cheerleading squad for 4 years.  Following my time in Lexington, I returned to Louisville, where I earned my Master’s degree in Secondary Education at the University of Louisville.  Upon graduation, I applied with Jefferson County Public Schools and have been a teacher in the school district since 2000. 


Before joining the eSchool staff as a science resource teacher, I taught science for 3 years at Iroquois High School and 9 years at Southern High School.  During my years with JCPS, I have taught biology and Integrated Science A and B.  While at Southern High School, I coached the girls cross country team.  While I enjoyed my time in the classroom, I am very excited to work with students in a new capacity at eSchool.  I believe online learning offers an excellent opportunity for students to earn high school and college credits while working at their own pace.
