Cal State San Marcos is home of the region’s premier event and conference center.  Consistent with the inspiration for the University – a quaint Italian town built into the hillside – The McMahan House incorporates separate buildings connected by pedestrian walkways and a central courtyard. The beautiful, rustic facility provides a peaceful and comfortable retreat from daily life while offering all the convenient amenities that ensure a successful event.  From intimate retreats to events for up to 150 individuals, The McMahan House is quickly becoming the region’s venue of choice.

A Brief History

In 2005, Richard and JoAn McMahan’s generous donation afforded the opportunity to create a complex of master planned buildings for Cal State San Marcos designed for entertaining and hosting special events for the community and the campus. The McMahans agreed that such a private and elegant venue would enhance Cal State San Marcos and the region. Thus, the idea for The McMahan House was born.

Located on the same knoll where the Prohoroff family lived (the owners of the poultry farm that once occupied the land where CSUSM is now located), The McMahan House occupies 3,200 square feet in four separate buildings that can host a variety of groups ranging from 16 to 150 guests. The existing cactus surrounding The McMahan House were part of the Prohoroff’s personal gardens and were preserved during the construction of the property to honor the history of the land.

During the ribbon cutting ceremony on July 15, 2009, President Karen Haynes said, “The edges of our campus are becoming blurred as we reach out to our neighbors and work together with them to create a better quality of life for all of us.”  As a premier event and conference venue, The McMahan House is specifically designed for external events, community outreach, presidential affairs, and special campus activities.
