Denholtz, the Red Bank-based investment management firm, officially solidified its status as a national powerhouse in one of real estate’s hottest sectors. According to the newly released Small Bay List’s Top Small Bay Owners of 2025, Denholtz ranked 10th in the United States, boasting a massive 5.3-million-square-foot portfolio as of year-end 2025.
Small Bay List, a premier data and market insights platform for the specialized industrial sector, ranks companies based on total square footage owned. For Denholtz, the top-ten ranking is the culmination of a multi-year strategy to dominate the “small bay” niche—industrial spaces typically used by local businesses, light manufacturers, and last-mile distributors.
While massive “big box” warehouses often make headlines, the small bay subsector has become a darling for investors due to a unique market imbalance: skyrocketing demand from local service providers paired with a severe lack of new construction.
“Small bay industrial is one of the fastest-growing subsectors… driven by strong tenant demand, limited supply, and its critical role in supporting last-mile logistics,” Mark Mahasky, senior vice president and head of acquisitions at Denholtz said. “Our approach is rooted in acquiring high-quality assets in infill markets where we can generate long-term value.”
The firm’s rise to the Top 10 follows a string of high-profile acquisitions across the Eastern United States. Denholtz has been particularly active in the Southeast and Midwest, recently closing on several multi-building portfolios:
- Florida: The five-building Anchor Industrial Portfolio in Casselberry (117,635 SF).
- Indiana: The four-building Park Elmwood Industrial Park in Indianapolis (133,200 SF).
- South Carolina: The four-building One Marcus Drive park in Greenville (103,647 SF).
These acquisitions complement Denholtz’s deep roots in the New Jersey and New York markets, bringing their total managed assets to over $2 billion across nearly eight million square feet of diversified real estate.
Founded in 1953, Denholtz has evolved from a local developer into a sophisticated, vertically integrated investment manager. By handling everything from acquisition and financing to day-to-day property management in-house, the firm has been able to maintain high performance across its industrial, residential, and mixed-use holdings.
With a staff of over 100 employees and a footprint stretching across the North and Southeastern U.S., Denholtz’s presence in the national Top 10 signals that the Red Bank firm is no longer just a regional player, but a major architect of the American industrial landscape.
