We, the principals of Idyllink, Robert Cashier and Shelley Bookspan, were the founders of PHR Environmental Consultants, Inc., a pioneer in the United States during the 1980s in advancing the goals of environmental site assessment, remedial investigation, pollution liability investigation, soil and groundwater cleanup, and resources analysis, preparatory to site restoration. As PHR, and in teams, we successfully completed environmental projects across the United States, including numerous Superfund projects. Idyllink reflects a continuation and refinement of our environmental cleanup and consulting work. The operating tenets of Idyllink that differentiate us from our competitors are:

  • Engage only the highest quality professionals, selected for the specific needs of each project
  • Remain cost-effective by maintaining low overhead and efficiency
  • Be nimble and responsive
  • Usher the project through all stages of operation to completion
  • Stay abreast of, and open to, new and creative solutions
