#2 time I got my cards

Hi there. I am showing that your flashcards were sent to your email right after you placed your order. You ordered/ purchased the digital flashcards that you can print. If you need a new email sent, I would be happy to do so, just let me know.

(Updated) Since you submitted a second poor review I will remind you like I did in my multiple responses and emails that you need to check your junk folder in your email. It has been sent at least 5 times and was confirmed received by the gmail server.

It's About You!

Hi There, My name is Brandon, also known as "The Sterile Guy." Besides my over 20 years of experience in the fields of Sterile Processing, Surgical Technology, and Infection Prevention, my most important focus is advancing the career fields of Sterile Processing and Surgical Technicians. SPD techs & OR techs are vital to the success of any medical procedure whether in the Operating Room or outlying clinics.

My goal is to equip SPD techs & OR techs with the knowledge, experience, and certifications they need to acquire the pay, benefits, and recognition they deserve. I started off simply producing YouTube videos teaching different aspects of each career field. During that time I was repeatedly asked to create materials to help others learn and achieve certifications. So that is what I did, and that is what this entire website is dedicated to. Don't hesitate to ask any questions you may have by clicking the message button at the bottom right of the screen and I will get back to you ASAP. Thanks for checking out the website, and I wish you nothing but success! ~Brandon
