Virginia Business //September 2, 2025//
After joining Monday Properties in 2005, Helmig has led the company to capital investments of more than $16 billion, expanded its multifamily portfolio to 6,500 units, and executed transactions totaling more than 36 million square feet.
Monday Properties has expanded its footprint into high-growth markets along the East Coast, from the greater New York City metro area into the Southeast. The company owns Nestlé’s U.S. headquarters in Arlington, as well as additional residential and commercial buildings.
Anthony Westreich, Helmig’s brother-in-law, founded Monday Properties and, in 2007, acquired a 2.5-million-square-foot Rosslyn portfolio two years after his father, the late Stanley Westreich, had sold the properties to Beacon Capital Partners for $960 million. In January, news broke that Monday lost the seven-building portfolio after defaulting on loans, and Beacon became the new owner.
Before joining Monday Properties, Helmig was a partner at Westfield Realty, co-founded by Stanley Westreich, where he oversaw approximately $5 billion in transactions. Helmig, a graduate of American University, is vice chair of the Rosslyn Business Improvement District board.
