Mr. Grennan was recently nominated for the 2022 CIO of the Year Award by the Society of Information Management (SIM) Chicago chapter and The Executives’ Club of Chicago.

Mr. Grennan’s previous role was serving as Chief Information Officer of Management Partners, Inc. (MPI), the parent company of two national Executive Search firms (Furst Group and Salveson Stetson Group) and a Leadership Development and talent management firm (NuBrick Partners). During his time there, he reworked the organization’s IT landscape, and during the onset of the Covid-19 pandemic, helped shift the company into a 100% work-from-home business model. He established an IT governance model, authoring and publishing both the IT Security and Risk Mitigation Policy and the Backup and Disaster Recovery Plan for each company, as well as created an IT Roadmap for long-term organizational outlook. Aging infrastructure was replaced and moved to the cloud, increasing efficiencies across the board. Increased IT security protocols were implemented to ensure safe storage of company data, and data safety awareness training was deployed for all employees throughout the company.

In previous roles, Mr. Grennan has served as a hospital system’s IT Project Manager, a Senior Technical Consultant (again with Wipfli), and a variety of technical roles within higher education.

Mr. Grennan earned his Master’s degree in Management Information Systems (MIS) in 2013 and his Bachelor’s degree in Computer Science in 2001, both from the University of Illinois. He also earned certifications in IT Project Management and Business Process Management.
