Subject: Application for Senior Financial Analyst – Daniel Okafor
Dear Ms. Rivera, I am writing to apply for the Senior Financial Analyst position at Cedar Health. As a financial analyst at Lumen Logistics, I rebuilt our monthly forecast model and cut the close from eight days to five, and I would like to bring the same focus on measurable results to your team. Your job description asks for forecasting, Excel modeling and SQL. These are a regular part of my work, and I would be glad to walk you through specific examples of how I have used them and what they achieved. What attracts me to Cedar Health in particular is your expansion into outpatient clinics and the finance team's part in planning it. It is the kind of work I want the next stage of my career to be built around. Thank you for considering my application. My resume is attached, and I would welcome the chance to discuss how I could contribute. Kind regards, Daniel Okafor
