Welcome to Dr. E. J. And Margaret O’Brien Hall

Marquette Business has a new home

Opened in 2023, O’Brien Hall is the new home for the College of Business Administration, Graduate School of Management, and the university’s innovation leadership programs.

This 109,000 square-foot four-story building features collaborative classroom, lab and study spaces, as well as an event space, café, faculty offices and dedicated areas for our nationally recognized Centers of Excellence. The first floor is designed to provide wraparound student support through centralized advising, a Student Success Center and a Business Career Center.

Since business isn’t done in a silo, this new facility emphasizes innovative, collaborative spaces where students are immersed in experiential learning and creative solutions. Here, future accountants team with aspiring marketers, and next-generation bankers map balance sheets with up-and-coming developers.

Movable wall partitions in rooms 150, 226, 436

Event / meeting organizers are responsible for positioning the wall as needed before their event, and returning the wall to the state shown below so it is ready for classes.

Spring 2024:

OB226: Partition wall will be closed/down at all times.  Please be prepared to open the wall if your event requires the entire space, and close it again when finished.

OB150 and OB436: There are various classrooms throughout the week requiring the electronic room dividers to be moved.  Please be prepared to open/close the wall as required.

  • OB150: Monday/Wednesday/Friday should start with divider UP and end with divider DOWN. Tuesday/Thursday should start with divider DOWN and end with divider UP.
  • OB436: Monday/Wednesday/Friday should start with divider UP and end with divider DOWN. Tuesday/Thursday should start with divider DOWN and end with divider UP.

See 3:12 for opening the wall

Important: When the wall is open, panels must be "stored" only against the exterior (west) wall of the room.  Only that side has the proper structural supports for the weight of the wall when opened.

Huddle areas

On the far end of most floors and in the cafe, there are huddle areas with display screens.
The display screens allow students or staff to connect a laptop either via the HDMI cable or via Crestron AirMedia.  Follow the instructions on the screen to use AirMedia to wirelessly share your screen from your laptop.  You may need to use the small Crestron control panel to switch between AirMedia and HDMI.  Huddle areas play digital signage messages when not in use, and will reset to digital signage each morning.
