Adventist Midwest Health appoints chief information officer

Hinsdale – Adventist Midwest Health has appointed Joseph C. Granneman as chief information officer. As chief information officer (CIO), a new position at Adventist Midwest Health, Granneman will direct and manage computing and information technology strategic plans, policies, programs and schedules for business and finance data processing, computer services, network communications, and management information services to accomplish corporate goals and objectives for the region. He is based at the Adventist Hinsdale Hospital campus.


Granneman, 40, of Cherry Valley, comes to the organization from Calamos Investments in Naperville, where he was manager of information security. Chief information officer (CIO) is a new position at Adventist Midwest Health.


Granneman earned a bachelor’s degree from Millikin University a master’s of business administration (MBA) from Northern Illinois University. He has more than 20 years of technology experience, primarily focused in healthcare information technology.


One of his biggest and most challenging projects will be the hospital system’s transition from a handwritten to computerized provider order entry process. The project involves more than 1,200 physicians and staff from numerous departments across all the hospitals, including information services, nursing and support staff.


“Computerized provider order entry is not a new system or application but rather a total process change that complements our existing electronic medical record system,” Granneman said. “I’m fortunate to be surrounded by a lot of great people who already have done a huge amount of work to ensure this project’s success.”


Granneman was hired following a nationwide search. He stood out among the many qualified job candidates because of his experience and enthusiasm.


“Joe is joining our team at a time when healthcare information services and technology is rapidly changing,” said Ron Wehtje, senior vice president and chief financial officer,
Adventist Midwest Health. “We’re confident he will be an asset to our organization.”


Prior to working at Calamos Investments, Granneman was chief technology officer and chief security officer for Rockford Health System, which was listed on Hospital and Health Network’s Top 100 Most Wired seven times. 


He is an active author and presenter in the health care IT and information security fields and has written articles for Information Security Magazine, CIO/CSO magazine, and Advance for Health Information Executives. He has also been interviewed by InfoWorld, Enterprise Systems, and Network World on various health care information technology and information security topics. He has presented around the country for the Healthcare Information and Management Systems Society (HIMSS) and International Data Group (IDG) on topics ranging from electronic medical records to risk management.


He has been active in many standards groups including the Health Information Security and Privacy Security Working Group for Illinois which developed an early framework for Health Information Exchange.  He was also a volunteer for Certification Commission for Health Information Technology (CCHIT) Security Working Group developing standards for the certification of electronic medical records. 


He joined the Adventist Midwest Health team March 7.
