Andrew Corch, Physical Education and Health Teacher

Andrew has been interested in physical fitness and wellness since he was a child. When he was in grade school he made sure his homework was done first thing so that he could go outside and play in the park next to his house. His love of sports and fitness carried through his Emmaus High School years where he played on the football team and excelled on the Marine Youth Physical Fitness team. During his senior year in 2004, he was the overall individual male champion at the National High School Marine Fitness Competition held in San Diego, California. He enjoyed those experiences so much that he decided teaching physical education and health would be a great career, as well as an excellent way to impart those interests to the young people in his community.

Andrew earned a Bachelor of Health and Physical Education degree at East Stroudsburg University in 2008, and a   Master of Health and Physical Education degree in 2013. In the summer, he supervises the playground program for the Allentown Parks and Recreation Department. He has also been the assistant coach for the Emmaus High School Marine Youth Physical Fitness Team since 2008.

At home, Andrew enjoys playing with his son.  He loves watching him grow and being a good father and role model to him.  When he’s not playing with his boy, Andrew loves any kind of exercise, because working out is where he feels most comfortable. He’s a huge fan of the Dallas Cowboys even though he tends to catch a lot of grief for that.

Carolan worked in the restaurant industry from the time she was in high school until 2008. For 17 years, she and her family owned a luncheonette in downtown Reading, Pennsylvania where she served as the manager, cook, and dishwasher at times.

She returned to Kutztown to pursue her master’s degree in 2013, and earned her master’s and reading specialist certification in the summer of 2015.

Mrs. Jennifer Miller, Art Educator
After graduating with a BFA (printmaking/illustration) from Rochester Institute of Technology, Jen worked for over ten years in the design industry as an Assistant Director in advertising, Layout Designer/Illustrator for Rodale Books, freelance Illustrator/Graphic Designer, and Art Director for a ribbon and pottery company.

Jen felt the pull of teaching, wanting to share her experience and passion in visual art. Witnessing the downfall of art in schools, she was determined to keep creativity as part of a strong foundation. She received her Education Certification (Art K-12) from Moravian College, and worked in the Allentown School District for six years before joining Seven Generations in 2010-11.

On a personal level, Jen loves to organize spaces and transform them into something functional and beautiful. She claims clutter makes her uncomfortable, but quirky surprises in unusual places make her laugh. Art is a big deal, and she prefers large-format, collaborative pieces. This can be in the form of work created individually and then placed together or an all-out, high-energy conglomeration of awesome.

A native of upstate New York, she prefers fall and winter. She feels landscapes are most beautiful with the changing colors that segue into snowy shapes. She jogs, skis, sleds, skates, snowshoes, and has been known to start a snowball fight or two. Or she’s off on travels with family and friends. She’s been throughout the USA, France, Belgium, Portugal, China, and Canada. Her favorite places so far are Paris, Northern California, Portugal, and home (Fogelsville). Contact Jennifer Miller at jen.miller@sevengen.org.

Johanna earned her B.A. in Environmental Studies from Gettysburg College in 2015 and she is currently working towards her Masters of Education in Environmental Education through Slippery Rock University. For the past six years, she has also spent her summers working at the Wildlands Conservancy.

Johanna always wanted to be a teacher, but it wasn’t until she got to Saucon Valley High School and began taking exciting science courses such as bioethics, ecology and environmental science that she discovered exactly what she wanted to teach. Her studies at Gettysburg enabled her to focus on environmental education and her time as a environmental educator summer camp counselor gave her practical skills. So when she learned about the Environment and Ecology position at Seven Generations, it was like her dream job came knocking on her door. She is very excited to combine her environmental, science and teaching passions at our school.

Her favorite place to be is outdoors so her favorite activities include hiking and camping. She also has a huge space in her heart for art and reading! Contact Johanna Roche at johanna.roche@sevengen.org.
