Suzi Rosen, PG, CHg, Principal and Managing Director for Environmental Solutions at Partner, expressed her enthusiasm for the new appointments: “We are thrilled to welcome Eric Smith to Partner and to see Gwen Tellegen take on her new role. Eric’s extensive experience in managing significant remediation projects and his deep understanding of the technical and regulatory aspects of environmental consulting make him a perfect fit for our team. Gwen’s proven leadership in developing niche market sectors will be instrumental as we continue to expand our services and support our clients’ needs.”

Smith’s career is marked by notable achievements, including managing the remediation of a former 56-acre oil refinery with 20 abandoned oil wells, which required the removal of 20 million pounds of deep soil hydrocarbon contamination. Smith’s expertise in hydrogeologic and geochemical conditions and remediation will be particularly beneficial as he joins Partner’s thought leadership team, addressing critical environmental issues today. Furthermore, his experience will help support the PFAS team with thought leadership as PFAS is a concern relating to groundwater and drinking water. “I am excited to join Partner and contribute to its growth and success. I look forward to working collaboratively with Suzi, Gwen, and the entire team to tackle challenging projects and mentor junior staff,” said Smith.

Gwen Tellegen, recognized for her success in developing niche markets within the environmental remediation sector, will lead a dedicated practice focused on the unique needs of the oil and gas industry and redevelopment of industrial properties. Tellegen’s transition to Senior Program Manager for Oil & Gas/Methane reflects the practice’s growth and Partner’s commitment to enhancing its capabilities. “I am honored to take on this new role and excited about the opportunity to further develop this niche technical sector,” said Tellegen. “Having Eric join our team is a tremendous advantage, and his expertise will greatly enhance our ability to support clients in this specialized sector.” Her leadership, combined with Smith’s technical expertise, will strengthen Partner’s service offerings and support clients in achieving their environmental goals. “Eric’s technical knowledge and leadership skills will be a tremendous asset as we continue to grow our practice and support our clients in achieving their environmental goals,” added Rosen.
