Industrial Service Group

What Industrial Service Group does

Industrial Service Group (ISG) is a privately held industrial services firm headquartered in Indianapolis, Indiana, with field operations in the Tampa/Hillsborough, Florida area. Founded in 1999, the company specializes in field remediation services and plant environmental services for industrial facilities, manufacturing plants, and contaminated sites. Its service portfolio spans 24-hour emergency spill response, field remediation (including lagoon closures, sludge stabilization, in-place sediment capping, AS/SVE remediation system installation and operation, and impacted soil excavation and removal), plant environmental services (tank cleaning, hydro-excavation, fluid and sludge pumping, industrial vacuum, hydroblasting, and regulated waste disposal), hazardous waste disposal, and site development work including grading and sewer installation.

ISG's underlying capability rests on specialized industrial remediation equipment — notably Air Sparging/Soil Vapor Extraction (AS/SVE) systems used for soil and groundwater treatment — combined with field crews trained for confined-space entry and emergency response. The business operates a direct enterprise sales model with no digital self-serve motion; customers contact the firm by phone (317-334-0921) for project quotes, and acquisition appears relationship-driven and supported by regulatory coordination with local, state, and federal agencies. Revenue is generated on a project-based professional services basis, with pricing quote-based and not publicly disclosed.

The company is independently operated with key leadership held by David Nirschl (Vice President) and Patrick Nirschl (Director of Operations), both based at the Indianapolis headquarters. No venture capital, private equity, or parent-company affiliations are evident in the available data, and headcount sits in the 11-50 range across the Midwest and Southeast US footprint.
