Teachers Federal Credit Union has sold its five-story 47,000 s/f corporate headquarters building located at 2410 North Ocean Ave. to Medford-based Soundview Realty Group. Leo Farrell and John O'Hara of the Hauppauge-based Corporate Realty Services, LLC brokered the sale. TFCU outgrew its facility, where it has been located for the past 30 years, and has decided to maintain a presence there by renovating and expanding the first floor where they will continue to operate their credit union branch. Paul Elliott, principal of Soundview Realty Group plans to renovate the remainder of the building including extensive interior and exterior upgrades. Meanwhile, TFCU has built-out new offices and has moved into their new corporate headquarters at 102 Motor Parkway in Hauppauge, which is a five-story, 200,000 s/f, class A, office building that they purchased last year. TFCU president/CEO, Robert Allen, says that they will relocate offices from Farmingville, Smithtown and Holbrook into the new building.
