I turn the books I love into bite-sized guides that help people decide what to read next. Back in high school-at a public school outside Columbus, Ohio-my classmates counted on my clear, concise summaries to study smarter, not harder. 


As I graduate this spring, I'm gearing up to pursue a degree in Digital Marketing and share my passion for reading by crafting engaging, actionable content for fellow book enthusiasts.
