Sam Delacroix Administrative Assistant New Orleans, LA | (555) 349-7721 | sam.delacroix@email.com Dear Nina Alvarez, I am applying for the Administrative Assistant role at Lakeside Partners. I am the person who keeps calendars honest, files findable, and meetings on time — and I genuinely enjoy it. I bring five years of experience supporting busy executives and teams with calm, reliable coordination. In my current role I manage scheduling for three directors, coordinate travel and expenses, and reorganized our shared filing system so the whole team stopped losing documents. I am proficient in the Microsoft 365 suite and quick to learn new tools. Lakeside's collaborative culture is the kind of place I do my best work. Thank you for your consideration — I would welcome the chance to show how my organization and dependability can support your team. Sincerely, Sam Delacroix
How to write a administrative assistant cover letter
Hiring managers screen administrative candidates for organization and follow-through before anything else — a strong administrative assistant cover letter proves both, then show the organization, communication, and follow-through that keep an office running.
Your resume lists the systems you've managed; the letter's job is to show the judgment behind them — a specific problem you caught or process you improved, in your own words.
Follow these steps to write yours.
1. Lead with a specific organizational result
Open with one concrete outcome — a process you streamlined, a scheduling conflict you resolved, an error you caught before it became a problem — rather than a general claim about being organized. A specific example does more convincing than any adjective.
2. Show you handle sensitive information with discretion
Reference how you manage confidential documents, schedules, or communications appropriately. This signals the trustworthiness hiring managers screen for in roles that touch sensitive information daily.
3. Close with your availability and a clear next step
Restate your interest, note your availability, and invite a conversation. Keep the sign-off professional and direct.
