About Us

Better health management begins at home
DxTerity is bringing the power of precision medicine to autoimmune disease.
We are pioneering the use of RNA-based immune system profiling to better understand the root causes of immune mediated conditions. Our goal is to provide more personalized care for autoimmune sufferers and empower patients with more detailed information about their condition so they can better navigate their complex health journey.
RNA testing is very different than DNA testing
RNA changes constantly based on environment, stress, nutrition, and illness, providing a more complete, dynamic picture of disease status. Our patented and proprietary innovations are bringing low-cost, precision testing to an underserved community.
Improving access to care, increasing healthcare equity and, saving patients time and effort is key to helping patients live their best lives possible. DxTerity’s at-home sample collection minimizes trips to labs and physician clinics, making disease monitoring significantly more convenient.

DxTerity is dedicated to partnering with stakeholders across the doctor-patient-testing process to improve health outcomes.

Leadership
Experience and vision
DxTerity’s leadership has extensive experience in advancing cutting-edge technology that redefines healthcare.
Robert Terbrueggen
CEO and Founder
Bob Terbrueggen, PhD, has more than 20 years of experience in the genomics industry. He started his career at Clinical Micro Sensors where he was Director of R&D and oversaw the development of the world’s first bio-electronic DNA detection platform, the e-Sensor. Following the company’s acquisition by Motorola, he became the Director of Research for Motorola Life Sciences.
In 2005, he helped start NanoBiomics, which was named best start-up of the year by the Arizona Biotech Association and was subsequently acquired by the Molecular Profiling Institute 9 months after founding. Bob is the inventor of DxTerity’s DxDirect Technology.
Bob double majored in Chemistry along with Cellular and Molecular Biology at University of Michigan and he received a PhD in Chemistry from the California Institute of Technology (Caltech).
He is an inventor on 26 issued US patents and more than 100 associated international patents.
James Healy
CFO and SVP Business Development, Co-Founder
Jim Healy, MS, has led operations, business development and finance for DxTerity since 2010. Prior to DxTerity, Jim had 25 years of operations and financial leadership in high technology, software and semiconductor companies. He started his career at Hughes and rose to be CFO and Director of Operations at Hughes Communication Products.
His leadership in the advanced technology group led to over $250M of new business, including the acquisition of Magnavox Radio division. Jim then cofounded JTA Research, a high speed semiconductor company, leading to a successful exit to Cadence Design Systems. After acquisition by Cadence and as VP of Business Development, he led new product introduction, M&A and supply chain initiatives expanding the Electric Design Automation Tools and Test Suite. Jim then took the role of CFO and SVP Business Development for Magnify360, an internet advertising start-up, where he raised capital and led business development activities for onsite behavioral targeting for Intuit, Seagate, ServiceMagic and Autobytel. These efforts led to a Top 10 List rating from Frost and Sullivan for marketing automation.
