Firm Overview

Ross & Baruzzini provides consulting and design expertise for diverse industries. Our market groups are populated by talented professionals spanning the services offered for each of our markets. We serve a range of agency and institutional clients that own and operate their own facilities and require long-term, high-performance solutions that are cost effective, energy efficient, and easy to maintain. We design and plan the systems that enable buildings to perform, including mechanical, electrical, plumbing, fire protection, communications, and more. By ensuring that these systems are fully integrated with each other and with the building structure, we help people, equipment, and processes operate with maximum efficiency and value.

An important distinction in Ross & Baruzzini’s integrated approach is the emphasis we place on both design and consulting. While each practice functions independently, they work together as a cohesive unit to create exceptional client experiences. Our consultants reference the past, imagine the future, and collaborate with our clients to shape their dreams. And our designers transform those dreams into inspiring, functional spaces that bring the vision to life.


Founded in 1953 by Donald Ross, an electrical engineer from MIT who also received his doctorate in industrial engineering, the firm welcomed Joseph Baruzzini as the mechanical principal in 1961. Together, they provided high quality, non-commodity engineering to a small group of blue-chip clients that valued the smart design and personal service that they delivered. In the late 1960s, Dr. Ross gained national attention with several patents in energy-efficient lighting design that helped secure research grants from Battelle Labs and the Electric Power and Research Institute to study the impact that lighting loads have on HVAC systems. The outcome of these studies led the US General Services Administration to adopt new lighting standards for all federal buildings in the early 1970s. Energy-efficient design is still the foundation of every building and infrastructure project the firm manages. In the 1980s, Ross & Baruzzini began to export specialized services outside our home base in St. Louis, Missouri, propelling an expansion that has led to new office locations in Miami, Indianapolis, New York, Los Angeles, Hamden (CT), Philadelphia, and Columbia (IL). Today, Ross & Baruzzini is a fully integrated design and consulting firm that serves clients directly or in collaboration with other architectural, engineering, program management or design/build teams for large building and enterprise infrastructure projects that require specialized design and consulting.
