230 W Monroe St, Suite 1400, Chicago, IL 60606

Dear Mr. Okonkwo,

A close cycle that runs five days instead of eight is not luck — it is checklists, automated journal entries, and a team that trusts the numbers before the deadline forces them to. At Lakeshore Industrial Group I rebuilt the month-end close for a four-entity, $180M manufacturer and compressed it from eight days to five, and I'd welcome the chance to bring that same discipline to the Senior Accountant role at Calumet Manufacturing Holdings.

Multi-entity manufacturing is the environment I know best. I reconcile 40-plus balance-sheet accounts each month and steward a $24M fixed-asset and prepaid portfolio at a 99.6% first-pass reconciliation rate, and I serve as primary liaison for the annual external audit — delivering three consecutive clean opinions with zero adjusting entries. When I redesigned our AP approval workflow and internal-control matrix, I surfaced $310K in annual savings and closed two SOX control gaps in the process.

I treat the integrity of the books as the foundation everything else in finance is built on.

I'm also the person who modernizes the close rather than just surviving it. I led our NetSuite ERP migration from QuickBooks across the AP, AR, and GL modules, cutting roughly 30 hours of manual data entry every month and freeing the team for analysis instead of keying. With nine years spanning public audit at Hartwell & Coe and corporate finance — plus my CPA and CMA credentials — I can move fluently between the controls a controller cares about and the reporting deadlines a manufacturer lives by.

I'd be glad to discuss how a faster, audit-ready close and tighter internal controls can support Calumet's growth. Thank you for your consideration; my resume is enclosed, and I'd happily walk through close documentation or references whenever it's useful.

Sincerely,

Grace Lin
