Over our three-decade history, PSARA has crafted a unique, tight-knit culture centered around integrity, commitment, collaboration, positive energy, and innovation.
Over 90% of our business comes from loyal clients.
PSARA was founded in 1986 with the mission of bringing a higher level of engineering and industrial hygiene to an emerging environmental remediation market. While we remain firmly rooted in the environmental remediation and restoration market, PSARA’s services have adapted over the years to meet client needs and changes in the environmental, health, and safety regulations. Over that time, PSARA has been fortunate to have contributed to some of the most significant environmental projects in the country.
