Bill Nicholas
Former City Manager at City of Sycamore

“I knew Tom Mangan and his excellent work before we worked with Geothink. Tom began work on a brownfield project the City of Sycamore tackled in about 2001. His role was to assist the city government in creating plans and specifications to meet EPA expectations and regulations relating to the site. The work took nearly a decade, and eventually Tom took his talents to Geothink which helped us complete the job. Tom is technically proficient, very knowledgeable about pertinent public regulations, well-known and respected in the Illinois state regulatory ranks, and very dedicated to the interests of his clients. His easy manner is particularly welcome as entangled regulatory and fiscal issues need sorting. I would strongly recommend his services in the future.”

“In July 2015 Charles Vincent George Architects (CVG) embarked on a development project with Packey Webb Ford on a 10 acre site along Ogden Avenue in Downers Grove IL. The site was previously a vehicle salvage yard from the 1930’s until the early 1980’s. Sitting vacant for over 30 years and after reviewing numerous failed development attempts from prior owners it became apparent this site was going to be difficult due to the many environmental contaminates and wetland areas. CVG began to interview environmental consultants and was given GeoThink’s (Tom Mangan) information from our Civil consultant, RASmith National. Tom Mangan provided an easy to follow, detailed proposed describing each task required for jurisdictional approval. After being awarded, Tom Mangan jumped both feet in to ensure wetland delineation occurred before close of season and scheduled site contamination investigations. In the end it took GeoThink 8 short months to provide any and all documentation, while working side-by-side with our Civil engineer, to secure State and local jurisdictional approval for construction to commence. GeoThink continues to monitor construction until the ultimate goal of securing a “No Further Remediation” (NFR) letter can be provides by State environmental officials. Tom’s attitude toward service to his client continues without question. That, coupled with his knowledge and experience, makes for an efficiently run approval process for the most complicated of projects. I look forward to future opportunities to work with Tom and GeoThink.”
