I earned a Master of Theology (ThM) in 2020 from Dallas Theological Seminary with an emphasis in ancient languages and linguistics, and I consistently earned excellent grades on all of my assignments. Because of my background in languages and linguistics, I'm great at grammar and syntax. I can quickly identify errors in spelling, punctuation, and grammar. Beyond that, I can identify ways to improve the clarity and general strength of your written communication. I have extensive experience in Chicago and Turabian formatting, but I have also worked with MLA. I have done extensive research and writing in the social sciences; however, I enjoy reading just about anything and would be happy to offer my thorough, punctual, and positive services to anyone who would like some extra eyes on a project.
I also offer tutoring in the following languages: Classical (Attic) Greek, Biblical (Koine) Greek, and Biblical Hebrew. Please send me a private message if you are interested in these tutoring services, and I would be happy to discuss rates (through upwork.com)
