May 12, 2025

Green Companies, Inc. (parent company of the HR Green family of engineering firms) has acquired Infrastructure Solution Services (ISS), a Florida-based civil engineering firm with offices in Melbourne and Sarasota and staff located in the Panama City area.

ISS, led by Brian Stahl and co-founded by Kiran Kulkarni in 2012, has extensive experience in water supply and treatment, stormwater management, civil site design, disaster recovery, surveying, and grant writing, providing services to government entities and private organizations. ISS is a strong local brand in the Florida market and is recognized for consistently exceeding client expectations.

“We’re proud to welcome the ISS team to HR Green,” said Jason Poppen, CEO of HR Green. “They’ve built a strong reputation through trusted relationships and quality engineering in Florida—exactly the kind of foundation we value. This partnership not only strengthens our water, municipal, and land development practices, but also deepens our commitment to growing in key regions with teams who share our values.”

Brian Stahl will continue to lead the Florida market as a Regional Director for HR Green, providing his local knowledge and leading the team in Florida.

“This strategic partnership provides a tremendous opportunity for our team and our clients. HR Green shares our commitment to quality and strong client relationships. This move lets us grow while continuing to support our communities—now with even more resources,” said Brian Stahl, Co-owner of ISS.

Florida is a strategic growth region for HR Green, and this merger of talent and resources allows the company to expand its geographic footprint and provide a broader range of services to Florida clients while maintaining the same level of service.
