Mission & Vision

At Doser, our primary goal is to enhance the quality of care that patients receive. We do this by developing advanced technological tools that enable pharmacists to deliver personalized therapy to patients. By helping pharmacists we also help doctors and therefore patients as well. By leveraging our cutting-edge technology and harnessing the expertise of pharmacists, we aim to empower healthcare providers with the tools they need to deliver exceptional patient care. 

“Every patient deserves medication with optimal results and minimal side effects”

Our story:

Doser was formed from a shared vision between our founders and a desire to fill healthcare industry needs. This was a desire to help those patients that no sees. These patients were not getting the optimal care. This realization inspired our founders to start Doser and embark on a mission to revolutionize how medicine is delivered. Our founders brought together a decade of expertise in 3D printing and the pharmaceutical industry to form Doser. Since then, they have been on an adventure to improve the care provided by pharmacists to patients.
