In 1993, Mr. Stefan Stamoulis, Principal Hydrogeologist, had a vision- to create a company based upon superior work and attentive customer service. With over twenty years of experience in groundwater and contaminant mobilization and delineation, Mr. Stamoulis firmly believes that customer service, top-quality product, and a positive and efficient work ethic ensure success. Hydrogeologic/Environmental Testing (H/ET) was founded upon this belief. Through controlled growth, careful cultivation of staff, and a clearly defined company philosophy, H/ET has accomplished and maintained these goals for the past 18 years.

Currently, H/ET enjoys a major market share within the solid waste industry in the Houston and extended Gulf Coast Region, and performs Phase ll Environmental Site Assessments (ESAs) in the Gulf Coast and Four Corners Regions, with offices in Alvin, Texas and in Mancos, Colorado. As H/ET ventures into other market segments, our goal remains the same: a dedicated team of professional geologists, hydrogeologists, field technicians, and administrative staff who are synchronized to perform and generate top-quality products and services within a timely manner to ensure total customer satisfaction.

Mr. Stamoulis and his staff also share in a belief that it is important to give back to the community. Employees at H/ET are encouraged to pursue various altruistic activities and ventures. Some of those ventures include volunteering with the Susan G. Komen Breast Cancer Foundation, the National Humane Society, and the Animal Shelter and Adoption of Galveston Island, Texas.

Mr. Stamoulis' personal activities include membership of the Board of the Moody Endowment, the Board of the Transitional Learning Center, the Board of Transitional Learning Center Institutional Review Board, and lastly, a community Board member of the Institutional Review Board Office of Research Services at the University of Texas Medical Branch, all of which are located on Galveston Island, Texas.
