At HRG, our staff is not focused solely on calculations and field data but on people - our clients; the men, women, and children they serve; our employees; and the citizens with whom we share the local community. That's why we strive - before any plans are prepared - to get to know the needs of all stakeholders, so that we can design innovative solutions tailored to meet everyone's unique needs.

We are able to do this first and foremost because of the depth and variety of our experience. Founded in 1962 as a sanitary engineering firm formed under the name Herbert Associates, Inc., HRG has been serving the needs of Pennsylvanians and citizens of the surrounding states for fifty years.

Full Service Capabilities
In this time, we have developed into a full service firm offering expertise in the areas of transportation, environmental site assessments, civil and water resources, site design, surveying, and GIS in addition to our initial specialty in water and wastewater engineering. This broad range of capabilities further enhances our ability to serve you by enabling us to handle every project need in-house from the initial project concept to project delivery. Why manage relationships with 3, 4, or 5 other firms when you can have everything done under the management of one firm and one project manager you trust?

Dedication to Quality Service
It's especially desirable to hand over a project from start to finish to one firm when you know that firm possesses such strict standards for quality assurance and quality control as HRG does. In accordance with our quality control procedures, a project-specific QA/QC plan is developed for each undertaking that identifies project-specific communications procedures, schedule milestones, and checking milestones to be followed by all individuals. What's more, HRG is always striving to improve our services through regular solicitation of client feedback.

In June 1962
Harry Herbert, Robert Rowland and John Strangarity founded a new firm, stressing business sense and quality service. These principles and integrity have sustained this firm for years and continue to foster decades of loyalty from our clients.

1960s – 1970s
When Herbert Associates, Inc., opened its doors for the first time that long hot summer, our founders had a storefront office, a card table, four chairs, and two clients. 

Initially, the firm concentrated in the environmental field, providing consulting services for the design of sewer systems, sewage treatment plants, water systems, and related public works projects. In addition, the firm was active in civil engineering and construction administration, specifically related to the development of recreational facilities. Major projects included the Swatara Township Authority Water Pollution Control Plant, the Steelton Water Filtration Control Plant, and the water and sewage facilities for the 1973 and 1977 National Boy Scout Jamborees.

By the end of the 1960s, the company had grown to employ ten people. In the decade that followed, the firm expanded our focus to include municipal engineering, which continues to be one of the foundations of our client base. As a testament to the quality of our service, we continue to serve many of these municipal clients more than 30 years later.

In 1981, we changed our name to Herbert, Rowland & Grubic, Inc., and co-founder Robert Rowland became president. Over the next 10 years, HRG diversified into a full service firm offering expanded capabilities in highway and bridge design, land development, financial consulting, and surveying. In addition, we cultivated new
opportunities in the private sector, which helped to fuel tremendous growth. By decade’s end, we opened our first regional office: in Lancaster. In 1989, current president Robert Grubic became CEO.

Under Grubic’s leadership, the firm continued to expand into new geographic markets throughout the 1990s, adding offices in State College in 1991, Gettysburg in 1993, Pittsburgh in 1994, and the Pocono Region in 1997. We also continued to diversify our service offerings with the addition of Geographic Information System and electrical engineering capabilities. 

From humble beginnings in that first storefront office, HRG has grown to encompass eight regional offices with 200 employees, and we have consistently ranked among Engineering News-Record’s Top 500 Design Firms since the end of the 1990s. 

The early years of the 21st century have seen HRG acquire two firms (Hickory Engineering in 2004 and Alliance Environmental Services in 2008). With the acquisition of Alliance Environmental Services, HRG has significantly expanded its capabilities in environmental compliance and remediation. Additionally, HRG became an employee-owned firm. 

In 2011, HRG opened an office in Morgantown, West Virginia and in 2013 the company expanded its footprint into Ohio, opening an office in Columbiana, Ohio. In the years that come, we anticipate even greater growth, fueled by our continued commitment to superior client service.
