Dear HR Manager:

I suspect you’ll find very few candidates with a background such as mine, and it’s one I’d like to put to work on your behalf. As you’ll see on the enclosed resume, the depth of my experience in information technology offers you the opportunity to hire someone who needs little or no training and who is comfortable and successful with a myriad of technologies.

Moreover, having worked as an IT professional in a variety of industries, including twenty-two years in the US Army, I have the background to work with and communicate effectively with management as well as customers. I believe that this ability will benefit your organization and bring you greater revenue. It is only due to the rapidly changing technologies that I have held positions at numerous companies. However, it is this fact that allows me to offer you such an unusual breadth of experience. I completed my Masters degree in IT Management from Webster University, graduate certificates from Villanova University in Advanced Information Assurance and Security – Government, Project Management Professional (PMP IT/IS), Information Technology Infrastructure Library (ITIL v3), and one Master Certificate: Master Certificate in IT Service Management. I have also obtained and/or working on the following certifications (completed certs are current):

• Certified Information Systems Security Professional (CISSP) – currently working towards

• CompTIA Advanced Security Practitioner (CASP)

• Computer Hacking Forensic Investigator (CHFI)

• Certified Ethical Hacker (CEH)

• Certified Network Defense Architect (CNDA)

• CompTIA Security+ (SEC+)

• CompTIA Linux+ (LINUX+)

• Information Technology Infrastructure Library Foundation (ITIL-F v3)

• Oracle Solaris (v10) Certified Associate (OSCA)

I know that I can be an added asset to your company as well as your company adding value to my personal and professional career. A personal interview would allow me to demonstrate my talents and to showcase one of my greatest assets, my people skills. I look forward to hearing from you so that we can schedule a meeting. Sincerely,

Lorenzo K. Mariner
