Montgomery & Associates (M&A) has a history of partnering with clients to address their evolving challenges. Our loyal base of clients includes municipalities, private water companies, government agencies, mining companies, industrial entities, and tribal groups who have come to expect state-of-the-art technical innovation combined with a strong, practical understanding of groundwater science. We employ a talented group of professionals in our U.S. and South American offices who specialize in hydrology, geology, soil science, policy and regulatory affairs, groundwater modeling, GIS analyses and 3D visualization, database management, and instrumentation and monitoring. Most of our principals have more than 20 years of experience; nearly all have master’s or doctoral degrees, along with one or more professional registrations. M&A staff members frequently present at conferences, participate in professional organizations, and serve on advisory boards.
Although M&A was officially founded in 1984 by Dr. Errol “Monte” Montgomery, our roots date back to the 1960s. The company grew out of Monte’s long professional affiliation with Dr. John Harshbarger, founder of the renowned Department of Hydrology & Water Resources at the University of Arizona.
Our corporate office is located in Tucson, Arizona. We also have U.S. branch offices in Phoenix, Arizona; Denver, Colorado; Salt Lake City, Utah; and Sacramento, California. Our South American offices are located in Santiago, Chile and Lima, Perú.
