Executive Team

Cristy Reiter


Cristy’s 25 years in the laboratory industry have been focused in laboratory sales management and operations. Before joining U.S. HealthTek, she served as Vice President of Sales at Spectrum Laboratory Network, Director of Business Development of Specialty Laboratories, Vice President of Operations at Clinical Pathology Laboratories (Virginia) and Senior Vice President of Sales at American Medical Laboratories.  Throughout her career she has overseen a variety of laboratory service components including Physician and Hospital Sales, Field Client Services, Client Service, Accessioning, Courier/Logistics and Phlebotomy.

As Chief Executive Officer, Cristy’s focus is on managing a financially lean, virtual company while reinvesting in product development.  She believes that hiring expert IT support should not be cost-prohibitive to our industry, and should instead allow clients a higher level productivity at a better ROI than by hiring full-time employees.

Robert Negosian

President & CTO

Robert considers himself lucky to have worked for over 25 years in the healthcare industry, because it’s one of the few industries that can have a direct impact on people’s lives. He’s worked in both Information Technology and Operations sectors and prides himself on his efforts to improve overall clinical outcomes not just for his clients, but for the patients they serve.

Robert’s work philosophy is that there is always room for an organization to improve its operations, and that the key to success is dependent on both technology and the right people. His work over the years with prominent world-leading laboratories, hospitals, physician offices and revenue cycle organizations has given him the opportunity to view all sides of the healthcare equation, so he knows that there is no single solution that works for everyone. He has a talent for quickly assessing problems and providing effective solutions, and always keeps a keen focus on ensuring a successful and reliable outcome for all parties.
