Dear Ms. Sprinkle,
Your recent ad on www.indeed.com seeking a Dental Technician is the cause for this cover letter. I know that I am the best candidate for this position, as you will see from this letter and attached resume.
I have been licensed as a Dental Technician, and have over 12 years working in this role. My present position is as a Dental Technician for Erie Family Health Center in which I work in a lab of only three Dental Technicians in a very high volume office. I ask that you take a look at my enclosed resume to learn more about how my experience and skills make me a well qualified applicant.
Thanks for your time. Please do not hesitate to call me at (555)-555-5555 with interest in scheduling a time to talk.
