new chapters during the decade. In 1984 Sigma Pi became an international organization upon the chartering of the first Canadian chapter (Zeta-Iota at Western Ontario), ushering the fraternity to change its name to the current title, Sigma Pi Fraternity International. In 1988, the fraternity was bequeathed the Rose Hill Farmstead by the family of founder George Martin Patterson. The property was visible from the Shadowwood headquarters. The fraternity sold the property to the Sigma Pi Educational Foundation in 1992. In 2003, the fraternity moved its international offices to Brentwood, TN as it was not as isolated as Vincennes. Being closer to a major city allowed for better access to airports and computer network infrastructure. The fraternity rented offices in the Gallatin Building until a property could be purchased. The fraternity sold the Shadowwood Estate in 2005 to a private individual. An office was found on Wilson Pike Circle and the fraternity's offices moved there in 2007. In 2013, the fraternity sold the property on Wilson Pike Circle and purchased the Mitchell House in Lebanon, Tennessee from Cracker Barrel Old Country Store for use as its headquarters. It held the grand opening of the building on March 29, 2014. After more than five years at the Mitchell House, the Executive Office moved to a new location near downtown Nashville and the Nashville International Airport. Alpha chapter at Vincennes University: preserving Sigma Pi's history After its founding in 1897, the Alpha chapter at Vincennes University closed in 1910. It remained dormant for 55 years until 1965 when the Alpha chapter was re-activated. Grand Sage Frank C. Fryburg worked with the students and administration at Vincennes to re-activate the chapter. However, the North American Interfraternity Conference prevented its members from opening chapters at 2 year Junior colleges. Honorary Grand Sage Curtis G. Shake was tasked with creating a formal petition to the NIC, which requested special dispensation be granted to Sigma Pi to reopen the chapter. The petition passed and on February 26, 1965, Alpha chapter was re-charted. In December 1970, the success of the Alpha chapter convinced the NIC to allow chapters at all junior colleges. A clock tower on the campus of Vincennes University commemorates the foundation of Sigma Pi. Despite Sigma Pi's diminished presence in the area after the move of its headquarters, the fraternity still recognizes and celebrates the university as its birthplace. The Alpha chapter is still active
