Samantha Tillie Holtgrewe is a freelance copyeditor, proofreader, and indexer. She started STH Editorial Services in 2018 after completing UC Berkeley Extension’s Sequence in Professional Editing and Indexing: Theory and Application courses.

Samantha earned a bachelor’s degree in Art from Skidmore College and has since worked in art education, college advising, administration and office management. She enjoys reading, creating art, crocheting, and cooking in her free time at home in Upstate New York.

Since she is new to the field, Samantha is eager to build experience and is open to taking on any and all types of projects. She is also happy to negotiate with authors and writers who may be working with smaller budgets–especially those who are also new to the industry.
