Bridge Engineering and New Bridge Design.
Bloom Companies, LLC is an engineering, architecture, and construction management practice founded in 1998 in Milwaukee, Wisconsin. Established by Mathew Tharaniyil, the organization initially focused on bridge and structural engineering, eventually expanding to cover transportation, architecture, electrical and controls, and design-build delivery. It has grown through key acquisitions, including Hay Dobbs in 2024 and Jendusa Design Build in 2025, and serves academic, municipal, transportation, industrial, and utility clients across multiple US offices and international locations.
