The American Concrete Institute (ACI) has promoted key staff members to increase alignment and flow from ACI’s technical documents to educational products.

Michael Tholen has been named managing director of engineering and professional development, Claire Hiltz has been named manager of professional development and Matthew Senecal has been named as manager, engineering. 

Tholen will coordinate the efforts and resources of both the engineering and professional development departments. He will continue the supervisory and coordination aspects of his previous position in the professional development department and act in a similar role for the engineering department. He will oversee the engineering staff in both departments to allow better interdepartmental coordination and align staffs' strengths with project requirements.

ACI’s engineering department will be under the direction of Senecal. He worked as a civil and structural engineer for 14 years before joining the ACI Engineering department in 2004, where he most recently served as senior engineer.

Hiltz will coordinate and implement programs necessary to increase the effectiveness and productivity of ACI professional development. Hiltz was previously course developer, professional development.
