About Us

Patients. Precision. Persistence.

Driving innovation of treatment care plans.

We exist to alleviate patient burden and give patients their lives back through full-service, digitized therapy platforms.

As the creator and developer of ReX, the only all-in-one oral dispensing medication wrapped in a customized digital therapy program and remote care management system, we empower healthcare organizations to engage patients while they are active in their treatment. The centralized system supports everyone in the care team, making patients’ lives easier by increasing adherence, delivering insights and facilitating intervention in real time, enabling communication and support between patients and their care team and improving trust and outcomes for all.

This is the future of Remote Specialty Pharmaceutical Care.

Our Story

Dosentrx was born out of a commitment to easing the burden and stress faced by chronic disease patients through state of the art, innovative treatment plans. With our 30-plus years of combined experience in healthcare and technology, we’re here to improve quality of life, trust and outcomes.

It all started with Mark and Natan, founders of ThreeWire, a twice-sold company that helped pharmaceutical companies expedite their specialty drugs through clinical trials with more efficient operations. Over 12 years, they saw the same patients, using the same medications and they saw first hand that there were real gaps in support and communication between patients and the care team.

Too much of the care plan rests on the shoulders of patients, who are already overwhelmed, who have little interaction with and exposure to their team between visits and little ownership over their care. Disparate sources meant to help patients, like reminder apps only solve part of the issue and tend to only add more layers of more things to remember further complicating lives. How can patients consistently stick to the plan? How can they be on top of their health and feel seen? How can they readily and reliably have access to their doctors? How can their team intervene at a moment's notice if something goes wrong?

On the care team side, it was evident that once patients leave the controlled trial and go out into the real world, no one had any clue if patients were taking their drugs as prescribed and at what level the care plan was adhered to. Natan and Mark knew this disconnect also had huge economic and clinical costs. This led to an epiphany - develop a device that reported in real time, how patients took their medication but also precisely dispensed the very same drug, and allowed for communication and immediate intervention of the care plan, if necessary.

As luck would have it, Natan’s father, Alan is an electrical engineer and he built a prototype that now has 5 patents. Mark and Natan sell ThreeWire, and with Alan start Dosentrx, bringing this all-in-one device, the ReX to light.  

Dosentrx is much more than the ReX, it is an extension of Mark and Natan’s commitment to making patient’s lives better and delivering solutions that drive innovation in remote specialty pharmaceutical care.

Vice President Product Management & Experience Design

Marcelle believes that the nexus point of highly analytical thinking and human-centered design, is the secret sauce to innovation. Marcelle has worked in high-tech since 2006, focusing the last 10-years on product design and leadership of complex systems in the MedTech and DevTech space.

“Patient-centric design must play a crucial role in the digitization of healthcare. No one wants to be sick, but if they are, navigating their therapies shouldn’t be an additional burden. Design and technology can make it happen.”
