PRESS RELEASE
SAN DIEGO, CA – March 10, 2026—AristaMD, a technology-enabled clinical services organization committed to solving the specialty care challenges faced by risk-bearing primary care organizations, today announced the appointment of Ken Chatfield as Chief Information and Technology Officer.
Chatfield brings over 30 years of experience in healthcare technology leadership, with a proven track record of leveraging advanced analytics to drive operational efficiency and clinical excellence, and is an early practitioner of Artificial Intelligence (AI).
“With experience implementing technical and analytics solutions in specialty care, primary care within at-risk practices and integrated delivery networks (IDNs), Ken brings unique deep experience to our team,” said Keith Pinter, CEO of AristaMD. “The use of technology in healthcare is 10 to 15 years behind mainstream business. As an experienced AI and machine learning practitioner, Ken will drive technology transformation, clinical change management and data insights that advance efficiency and quality of care. These improvements will accelerate our ability to improve access to a comprehensive specialty care management solution.”
The appointment comes as AristaMD accelerates the technical evolution of SpecialtyCare360, a suite of services designed for risk-bearing primary care organizations, wherein it is flipping the script, moving from a reactive approach to patient care to proactive (identifying at-risk patients early & ensuring they receive the appropriate preventative care essential to effective chronic disease management). Chatfield will oversee technical strategy and performance oversight.
“I am excited to join AristaMD at a moment when information and technology are the primary catalyst for improving specialty care access,” said Ken Chatfield, CIO and CTO of AristaMD. “I am committed to ensuring our primary care partners have the predictive analytics and real-time informatics they need to manage patient populations effectively while reducing the medical loss ratio.”
Rather than immediately referring patients to specialists, primary care providers leverage AristaMD to access timely specialist advice—using eConsults and telehealth when appropriate. The comprehensive specialty care services also include evidence-based care design as well as care navigation, support and coaching. These services rely on both technology and analytics to ensure appropriate intervention occurs before the patient’s symptoms escalate or chronic diseases become unmanaged.
AristaMD leverages advanced analytics to predict care needs, optimize resources, and identify the best care pathways to deliver higher-quality, more cost-effective care. The model keeps the primary care provider at the center of care and deploys human connections, including specialists and care coordinators, to ensure technology and predictive analytics deliver smarter, more efficient, and more cost-effective patient care.
“By integrating technical efficiency into our core delivery model, we are empowering primary care providers to manage the specialty care journey with unprecedented precision,” added Chatfield. “I look forward to helping AristaMD lead the industry in data-informed specialty care orchestration.”
Chatfield’s career is defined by his ability to bridge the gap between innovative technology and complex clinical operations. Most recently, as CIO and Investor at Options Medical Weight Loss, he deployed proprietary predictive analytics models that optimized care delivery across dozens of locations. As CIO of US Acute Care Solutions, Chatfield led enterprise-wide data initiatives and telemedicine deployments. Previously, as CIO of Envision Physician Services, he was a key leader in scaling the organization into a $6.5 billion unified multi-specialty medical group.
Chatfield holds multiple patents, including innovations in natural language processing for electronic medical record systems. He holds a Bachelor of Science in Information Management from Brigham Young University.
