Grace Consulting

What Grace Consulting does

Grace Consulting, Inc. (GCI) is a US-based air emissions stack testing firm founded in 2000 and headquartered in Wellington, Ohio, with additional field offices in North Carolina, Indiana, and Texas (opened January 2025). The company is self-described as the nation's largest privately-held stack testing company and was acquired by Alliance Technical Group in August 2025, now operating as 'An Alliance Technical Group Company.' GCI performs industrial air emissions direct source sampling and analytical services using USEPA, ASTM, CTM/OTM, NIOSH, and NCASI methodologies, delivered through a fleet of 18 mobile monitoring laboratory trailers that mobilize to client sites across all 50 states and select international locations.

GCI's core technology stack centers on physical instrumentation rather than software: its patented Precision Flow© multi-probe electronic flow measurement system (Methods 2G and 2H) reduces high bias by up to 10% and pollutant measurements by up to 8% compared to manual methods, FTIR spectroscopy enables real-time detection of target compounds (HCl, CH2O, NH3), and specialized mercury testing capabilities (Methods 29, 30B, 101A, Ontario Hydro) are supported by three mobile labs with on-site sorbent trap analysis. The company maintains NELAP accreditation for both brick-and-mortar and mobile laboratories, STAC/A2LA AETB accreditation, and ASTM D7036-04 compliance, making it one of the few firms in the nation with this regulatory stack. Over 50 test technicians led by certified crew chiefs with 15-20 years of minimum experience deliver the work.

GCI generates revenue through project-based professional services contracts (quote-based, multi-year) with no public pricing, primarily serving utilities and power generation, industrial manufacturing (chemical, cement, steel, glass, pharmaceutical, pulp & paper), oil/gas/refining, and a smaller share of municipalities and food/ethanol facilities. Customer acquisition runs through direct B2B enterprise field sales via phone (1-877-GCI-TEST), email, and website proposal requests, with a deliberately limited digital marketing presence. Quantified customer outcomes include a documented $5M annual savings case for a Midwest utility via Precision Flow© CEMS curve adjustments, zero accidents over the past five years, and draft report turnaround of 1-3 weeks.
