Dan has also had significant experience in preparing and reviewing CEQA documents (EIR, IS/MND, Cat Ex, etc.) and permit applications for a variety of projects.


Prior to working at WWR, Dan studied aquatic ecosystem ecology and ecological engineering at The Ohio State University. As a research associate at Ohio State he contributed to river and wetland restoration projects throughout Ohio and worked on a team that developed and studied a pilot-scale wastewater treatment wetland system at the Ohio State dairy farm. As an intern with the Pennsylvania Department of Environmental Protection, Dan worked with engineers and geologists on abandoned coal mine reclamation projects in western and northern Pennsylvania.
