PRO TIP

If you can't find the hiring manager's name, never use the generic “To Whom It May Concern.“ There are better ways to address a cover letter without a name, such as “Dear Hiring Manager.“

STEP 2

Introduce yourself in the opening paragraph

Your senior administrative assistant cover letter must quickly capture the hiring manager's attention. Introduce yourself with your professional title and key qualifications, such as in-demand skills or specialized expertise. For example, see how these two opening paragraph examples compare:

Strong opening paragraph example:

As an administrative assistant with over 10 years of experience, I am eager to apply for the senior administrative assistant position at Nationwide Financial Services. My attention to detail and multitasking skills are strengthened by successfully organizing over 50 company-wide events annually, enhancing collaboration and productivity. My expertise aligns well with your team’s needs and goals.

Cross icon

Weak opening paragraph example:

Hey there, I'm reaching out about the senior administrative assistant job at OfficePro Solutions. I've got some experience in admin tasks and think I'd do well in this role.

PRO TIP

If a current employee has referred you for this position, mention this in the opening paragraph. Our referral cover letter openings article shows you how to do this.

STEP 3

Share relevant achievements in the body paragraph

Use your senior administrative assistant cover letter's body paragraph to differentiate yourself from other job seekers by expanding on a specific achievement, providing insight into your career goals, or sharing a little bit about your work ethic and values.

Check icon

Strong body paragraph example:

In my role as an administrative assistant, I transformed office operations through efficiency improvements, increasing productivity by 35%. Leading a calendar optimization initiative, I streamlined scheduling, reducing conflicts by 25%. Additionally, I enhanced document management, cutting retrieval time by 20% and boosting workflow. My attention to detail and organizational skills were pivotal in achieving these goals, making me eager to apply these strengths to your team as a senior administrative assistant.

Cross icon

Weak body paragraph example:

I'm interested in the senior administrative assistant role because I need to advance my career and think it will help me. I have some admin skills, but I mostly rely on others. I haven't handled major tasks yet, but hope to learn. I'd try hard to meet expectations in this position.

STEP 4

Finish by encouraging next steps

Your cover letter's final paragraph should summarize what makes you an ideal candidate and expressly mention you're eager for the opportunity and a future job interview. Remember to close with an appropriate sign-off and sign with your name.

Check icon

Strong closing paragraph:

My extensive experience in managing office operations and supporting executives ensures I am well-prepared to make an impactful contribution to Brightstone Solutions. I am eager to bring my organizational skills and attention to detail to your team. I would welcome the opportunity for an interview to discuss how I can support your goals. Thank you for considering my application.
Best regards,
