The Birch Group, a privately-held commercial real estate investor, owner and operator based in Nanuet, recently announced the hire of Mike Lyberatos as vice president of property management and construction. Lyberatos joins the firm at a period of immense growth and activity, as The Birch Group leased almost 200,000 square-feet to tenants across its portfolio throughout 2021. The announcement follows the company’s major portfolio purchases in Jericho, NY and Short Hills, N.J, and its strategic focus to acquire prime office assets across the tri-state area.
