Mission Statement

For over 40 years, the Institute has met the evolving needs of Long Island real estate professionals and of the industry they serve.  Capitalizing on its affiliation with the School of Business at Stony Brook University and on the experience of its board of directors, the Institute serves as a respected spokes person on contemporary issues and as a resource for professional career development through symposia, white papers, luncheons, course work and social media. Equally important is its commitment to meeting the needs of entrants into the real estate community by providing hands-on training, meaningful internships, networking opportunities, scholarships and future graduate programs.

It is with great sadness that we mourn the loss of John J. Gutleber. We extend our condolences to his wife Fran, his daughters Stephanie, Jacklyn, and Megan, his step daughter Lauren and stepson Cory his brother Ed and sisters Irene, Therese, Kelly and Ann. Condolences also extend to his colleagues and working family including Frank and Rita Castagna and the entire staff at Castagna Realty Co., Inc. John was a true mentor and friend to many and we are blessed to have known him. His work ethic, intelligence, compassion and quick wit are just some of the great qualities he possessed, but first and foremost was his love of family. John will be missed dearly but not forgotten. Thank you “Tex”!
