She served as controller for these two firms, managing the financial reporting, loan servicing, investor reporting, and communications, as well as the quarterly valuation processes. In 2011, she was promoted to the Director of Asset Management at LEM Capital, where she oversaw the entire real estate investment portfolio that was ~10,000 units by the time of her departure in late 2015.
