The sterile guy saved me!
Just passed my CRCST thanks to Sterile Guy! Super helpful questions and format were on point. Highly recommend for prep!
I bought the CER practice test the day before my exam. I didn’t know what to expect but surprisingly the practice test covered the same material that’s on the CER exam. Honestly if I didn’t buy the practice test I wouldn’t have passed. Thanks to The Sterile Guy I’m CER certified!
Such a great way to get yourself ready for the CIS exam. I used these practice test and was able to pass the exam on the first try. Thank you On to CHL next.
I am still studying to take the exam! So far I love the materials. I am taking my time studying but I can’t wait to take it soon just so I can see if the study guide here are helpful for the exam. I will leave another review after I take the exam soon.
This bundle I bought is very helpful and is definitely helping me prepare for the test. I just keep retake the practice exam until I know I’m ready but definitely one of the best practices test and bundle out here.
Passed the exam and got certified as CHL after reviewing your course for a week ... I got some 20 to 22 questions from your content in the exam out of 150 questions... not bad ...
I literally took my test twice and wasn’t able to pass I almost gave up but I said let me try out this guy that all
The techs been telling me course , and I passed finally !! I would definitely recommend this course.
I really enjoy studying on the Sterile Guy page, all the information that is available on here is Fantastic! Waiting to get my test date and when I do I’ll be back to let you know how well this site is!! Thanks
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
