Greg's experience has included technical and project management roles for a variety of environmental projects including sediment and upland site investigation and remediation efforts, water resources, wastewater treatment, and potable water treatment as well as technical support to litigation activities. Many of his projects have been conducted under strict legal and confidentiality requirements.
Greg has been actively involved in two sediment mega-site projects: the Onondaga Lake in New York and the Berry's Creek Study Area Superfund Sites in New Jersey. For the Onondaga Lake project, Greg headed up the assessment of dredging options including dredge spoil management for the feasibility study (FS). He is serving as deputy project manager for the Berry's Creek Study Area project FS effort.

Successful projects have included directing the design of upland site remediation measures to be implemented in conjunction with the clean-up of Onondaga Lake. He has also provided consulting or project management expertise to several U.S. EPA Superfund RI/FS projects for potentially responsible parties or under the direction of counsel, including the Riverfront NPL Site in New Haven, Missouri and the Onondaga Lake NPL Site in Syracuse, New York.
