The GWU Writing Center is available to help! From their website:
The University Writing Center offers members of the GW community opportunities to receive dedicated attention to their writing and research projects at all stages of the writing process. Our trained writing consultants work with writers from the first-year college experience up through post-doctorate and faculty levels. Rather than providing proofreading and editing, the Writing Center works to help the people who come through our doors strengthen their abilities as writers and to become stronger editors of their own work.
