The Sebago Way – Since 1981

Sebago Technics was founded by Walter P. Stinson, P.E., in 1981.  Working from his kitchen table, he began with a commitment to serve customers with integrity, respect and responsive service. Early on, Walt foresaw the benefits of a multi-discipline engineering company. Accordingly, he earned licensure/certification as a professional engineer, professional land surveyor, certified soils scientist and licensed soil evaluator. Walt and Sebago quickly earned the respect and loyalty of residential and commercial developers, local officials and the contracting community.  These relationships continue today and are an important element of the company’s and its clients’ success.

1984 – Sebago Technics added surveying as a full-time discipline with the employment of Charles L. Brown, Jr. P.L.S. Charlie brought experienced and responsive survey services to Sebago’s clients. Sebago has always viewed survey services as the critical foundation for any successful design and engineering. Moreover, the ability to control the schedule of survey services has allowed Sebago to be more efficient in its project delivery than survey-only or engineering-only services firms.

1988 – Sebago began offering Landscape Architecture services to its clients. With the addition of William T. Conway, R.L.A and three other Landscape Architects, Sebago could seamlessly integrate landscape planning and design into its projects. This value-added capability quickly transformed projects from just being well-engineered to being well designed. Sebago’s Landscape Architects are accomplished, practical land planners who are able to conceive and conceptualize the optimal site layout and finished look of projects. In this manner, they are an invaluable resource to our engineers and clients alike.

1990 – Brought the addition of Environmental and Natural Resources Services to the Sebago lineup. Sebago was now able to offer environmental engineering, environmental site assessments (Phase 1, Phase 2, VRAPs), engineered septic systems, wetlands/vernal pool delineation, along with soil science and septic design. These services allowed Sebago to move into new markets of environmental remediation, sewer system design and state/federal environmental projects.

1998 – On December 31, 1998, the Employee Stock Ownership Plan (ESOP) was implemented.

1999 – Transportation and Traffic Engineering services further expanded the disciplines provided by Sebago. Stephen S. Sawyer, P.E. was hired to head up the sector with more than 25 years of transportation experience at a large national transportation firm. Over the years, this discipline has increased Sebago’s government sector work with projects for Departments of Transportation in ME, NH, and VT; municipalities; and regional transportation agencies. In addition, we are able to provide private sector clients with traffic studies, traffic movement permitting services and off-site highway improvement designs. In the past few years, Sebago’s transportation professionals have developed niche services in traffic signal operations using their in-house Traffic Management Center, and are actively involved in several Connected Vehicle projects in NH and ME.

2000 – 2003 – The early 2000’s marked an exciting time in the company’s history. Building on our early Total Quality efforts and subsequent reorganization in the mid-90s, the ESOP purchased its first batch of shares, which placed Sebago Technics on the path to becoming an employee-owned company. At the start of the new millennium, the Sebago Technics ESOP Trust owned nearly 10 percent of the company. In October of 2003, the Sebago ESOP reached another milestone when a major transaction took place which brought the Trust ownership to 62 percent achieving “majority ownership” of the company.

2006 – Sebago Technics acquires Technical Services Incorporated (TSI) out of Auburn, Maine.  TSI was a civil/survey engineering firm with a great reputation and market share in the greater Lewiston-Auburn area.
