Mission Statement

Saving kids’ lives by making critical dosing errors a thing of the past.

About Us

CertaDoseTM offers a unique measuring system that helps eliminate dosing errors in kids by using any of the industry standard methods of estimating a patient’s weight, including length and age, and automatically converts that weight to the appropriate dosage on our color-coded syringe.

Dr. Caleb Hernandez is the creator of the CertaDoseTM syringe and the company’s Chief Medical Officer. He is an attending physician in the Emergency Department for University of Colorado Health, is Board Certified in Emergency Medicine by the American Board of Emergency Medicine, and a Fellow for the American College of Emergency Physicians.

Dr. Hernandez’s personal experience with saving a child’s life by preventing an accidental overdose of 10-times the correct amount inspired him to invent a solution for such medical errors and adverse drug events. This is how CertaDoseTM was born. Dr. Hernandez has published multiple articles in peer-reviewed journals on these subjects and regularly speaks at emergency medicine conferences.
