In this pristine, tranquil setting, we specialize in inspiring attendees in meetings, conferences and retreats to think most creatively, learn most efficiently and perform most effectively. Allerton Retreat Center is treasured by corporate executives and conference planners nationwide who have sampled the character and atmosphere at this turn-of-the-twentieth-century mansion, and capitalized on the opportunity it affords for quiet reflection and truly creative thinking.

Away from the distractions and noise of city life, conference guests enjoy luxurious surroundings in a Georgian-style mansion with exquisite wood floors, marble fireplaces, elegant furnishing, and breathtaking views of the surrounding meadow, reflecting pond, and woodlands which are teeming with birds and wildlife.

Allerton has four meeting spaces available within the main house: 

THE LIBRARY: The two-story Library with doors to the adjoining terrace, seats 120 persons, theater-style, or up to 50 at classroom style tables.
