Our Engineered Solutions Group can design cost and time-saving solutions that include vapor control, chemical cleaning, tank cleaning, water treatment, hydroexcavation, explosive deslagging, abrasive blasting, boiler cleaning, hydrocutting, vacuum services, and hydroblasting to support turnarounds and daily work as a standalone or fully integrated solution.


With over 30 locations, evergreen North America was formed in June 2016 when The Sterling Group purchased Evergreen Industrial Serices (EIS) and North American Industrial Services (NAIS) to create a national footprint capable of supporting its customers throughout the U.S.

NorthAmerican Services Group

NAIS was founding in 1994 by Frank and Tim Ziilka. Like EIS, NAIS grew from a startup to a large regional provider servicing power generation, paper, mining, refinery, petrochemical, and industrial clients in the Northeast, Midwest, Southeast, and Western regions of the U.S.


EIS was founded in 2000 by Jon Hodges and grew from a startup to a large, regional provider. EIS services many of the largest refineries, petrochemical facilities, and power generation plants along the Gulf Coast.


In January 2015, EIS acquired GEM Mobile Treament Services to expand its services to include vapor combustion, vapor scrubbing, thermal oxidation, water treatment, and custom engineered customer solutions.


After achieving success as regional industrial services entrepreneurs, Jon Hodges (EIS) along with Frank and Tim Zilka (NAIS), realized they could better serve their clients by combining their businesses to provide the scale and industrial service capabilities their growing customer base was demanding.

Many discerning customers are seeking a national partner with superior engineering expertise that can minimize downtime and reduce costs during planned outages and when providing daily industrial services support.


By combining the capabilities of EIS, GEM, and NAIS, Evergreen North America provides its customers with state-of-the-art engineered solutions and best-in-class automated industrial services.
