Hannah Rosenfield

Mathematics and Statistics Tutor, Founder

Math was not always fun for me. In fact, I dropped into the lowest level class in high school and told my teacher that I would never use math again in my life. It wasn't until I studied with a great tutor to fill in my knowledge gaps that things changed. I found someone who believed in me, encouraged me, and convinced me that I was capable of true mastery. Slowly, concepts that had once seemed so daunting and impossible became comfortable and even enjoyable. With this new-found belief in myself, math suddenly became fun.

Thanks to my improvements, I was accepted into prestigious universities including Carnegie Mellon University and New York University. During my year at Carnegie Mellon, I was on the Dean's List with High Honors in both fall 2017 and spring 2018. I was a member of Lambda Sigma and a Dietrich College Peer Advisor. I also played on the varsity tennis team and was an ITA Scholar. 

I later transferred to the University of Florida, where I obtained a Bachelor of Science in statistics with a minor in business administration.

I was born in Manchester, England. Although I have lived in Florida for almost all of my life, I like to think I have still managed to keep my British accent. I love cats, Disney, the ocean, podcasts, and any type of trivia game or brain teaser.

John Cheesman

ELA Tutor

I have been an educator working out of the Philadelphia area since 2016 after earning my BA in Comparative Literature (focus Spanish and French) from Middlebury College. I began my practice tutoring English, and I expanded over time to work with students in a wide range of subjects. Since 2020, I have been focused on ELA and test prep instruction for high school students. I am a pro editor, ready to help you punch up your essays and understand the fundamentals necessary to make your writing as effective and effortless as it can be. I am also an ACT and Digital SAT expert; wherever you are starting from, I will help you level up. 

My practice as an educator is centered on a student led approach. Students can expect me to ask lots of questions, and should be prepared to do most of the heavy lifting themselves. I strive to cultivate confidence, independence, and a love for learning in each student I work with. By building up fundamental skills, executive functioning abilities, and mental endurance, I will make sure students are prepared to tackle not only the material they bring to sessions, but whatever else life throws their way. 

When I am not working with students, I am a writer, editor, and translator. I also love to garden, bike, and spend time outdoors. I am a reader and a learner, and I always have a new interest to share with students. 

Erica Holtgraver

Chemistry Tutor

While I was completing my undergraduate Bachelor of Science in Chemistry, I began tutoring Organic Chemistry and fell in love with teaching, which led me to complete my Masters degree in Secondary Science Education. From there, I worked for seven years at a rigorous independent college prep high school teaching Honors Chemistry and AP Chemistry in a caring, individualized way. 

I've worked with hundreds of high school students to improve their Chemistry and AP Chemistry performance, scores on standardized exams, and most importantly their understanding of the content. Some of my students have gone on to attend Ivy League Schools and competitive medical programs (including the Lake Erie College of Osteopathic Medicine).

I take an organized, simple, and social approach to teaching chemistry. I love getting to know my students and what they are interested in, so that I can make our lessons fun and engaging. Chemistry is truly a beautiful subject that can give us insights into life, energy, and materials. In the words of Carl Sagan, "We are all made of star stuff".
