Streamline USA, LLC is a New York City-based General Contractor and Construction Management Company founded by three partners who have known each other for many years and finally decided to work together as a team. Eric Ortense, Liam Treanor, and Orin Zelenak collectively possess over fifty years of diverse construction experience and this enables them to engage in commercial, hospitality, and high-end residential projects.

This team came together with a vision that each member would bring his own unique talents and problem-solving abilities to bear. By combining a passion for construction and the synergy of a partnership, Streamline has continued to grow stronger while remaining agile and dynamic.
