Prominent Cincinnati real estate pro leaves longtime firm to join Colliers

May 25, 2026 - 23:34

A well-known figure in Cincinnati's commercial real estate scene has made a significant career move. Josh Rothstein, a veteran broker with a strong track record in retail property, left OnSite Retail Group in mid-May to join the global firm Colliers. Rothstein had been with OnSite for many years, building a reputation for handling complex leasing and investment sales in the region.

His transition to Colliers marks a strategic shift for the company, which has been expanding its local retail advisory practice. Rothstein will serve as a senior vice president, focusing on tenant representation and landlord services. He brings with him a portfolio of high-profile clients and a deep understanding of the Cincinnati market, from urban core developments to suburban shopping centers.

Industry observers note that Rothstein's move reflects a broader trend of top talent gravitating toward larger, full-service platforms. Colliers, with its international reach and data-driven resources, offers a different scale of support compared to the boutique environment of OnSite. For Rothstein, the decision was about access to a wider network and the ability to offer clients more comprehensive solutions.

OnSite Retail Group has not announced a replacement for Rothstein, but the firm remains active in the local market. Rothstein's departure is seen as a notable loss for the company, though his new role is expected to keep him closely tied to the same Cincinnati properties and relationships he has cultivated over his career.
