Meet the Gynzy authors

Learn about the educators creating Gynzy lessons.


Gynzy authors are a team of educators. With different educational backgrounds and personal experiences, they’re able to collaborate and create engaging lesson content across various subjects.

While authors use their creativity to make each lesson unique, our lessons have a consistent structure to ensure students can build on prior knowledge, develop an understanding of new information, and be quizzed on the information they’ve learned.

Kim Fowler

“I’m a former third-grade classroom teacher with a Master’s Degree in Elementary Education. I’ve worked in several fields over the years but returned to my passion for teaching in 2018 when I started teaching online. I’ve branched out into Instructional Design and Writing because I really enjoy creating innovative and unique ways for students to learn! Parents have told me that my level of patience is extraordinary. I credit this to being the oldest of four children and having two, now grown, kids of my own!”

“I’m a former English and Computer Science teacher to both middle and high school students. I have a Masters in Information Technology Management, and have a passion for helping students learn through innovative and modern techniques. I have created over 100 lessons for Gynzy and absolutely love utilizing their adjustable clock, spin the wheel, and hour glass tools! When I’m not creating lessons you can find me reading, hiking, baking, or hanging out with my family!”

Mary Phelan

Mary is a middle school teacher for the NYCDOE with a Master’s Degree in Secondary English Language Arts and a Bachelor’s Degree in Teaching English to Speakers of Other Languages (TESOL). She is inspired by her students from all over the world who speak multiple languages. In her lessons, Mary encourages class discussion as much as possible. She believes that discussion allows us to learn from one another and develop ideas that might not have occurred to us without speaking with our peers. In her spare time, she is also an artist and she owns a mural company (@lehigh_mural) with her sister!
