About Us

Shamrock Environmental Corporation (Shamrock) was founded in July 1994 by the McGroarty family as a grass roots industrial services and wastewater treatment company. Today, co-owners Gail McGroarty and Greg Kiser operate one of the premiere full-service environmental service companies in the southeastern and mid-atlantic region of the United States. Shamrock, headquartered in Browns Summit, NC, has 5 office locations, approximately 150 full-time employees and performed projects in 38 states in the USA.

Since its inception, Shamrock has remained committed to the business model of “self-perform” all core services. To support this philosophy, the company has invested significant capital in facilities, equipment, safety programs, training, regulatory compliance, new technology and the dedicated, talented employees of Shamrock. The Shamrock way, “self-perform”, has rewarded the company with a loyal customer base across all industry sectors, an excellent reputation in the marketplace, geographic expansion opportunities and stability.

While capital investment in facilities, equipment, regulatory compliance and new technology is a sign of long term commitment and reliable performance, the most compelling difference between Shamrock and all other environmental service providers is the expertise, dedication, talent and safety practices of the Shamrock employees. Shamrock’s strength is our people!
