My ideal project allows me to apply new approaches to old problems. 
Josh has more than 11 years of experience in the environmental consulting industry. He has extensive groundwater monitoring knowledge, including monitoring well installation, destruction, development, and different sampling techniques. Additionally, Josh has performed numerous Phase I ESAs, Phase II geologic/hydrogeologic investigations, construction/remedial excavation oversight, in-situ remedial injection, and is familiar with many different subsurface drilling methods.
When Josh is not managing the groundwater monitoring program at The Presidio or other large-scale remediation and monitoring programs, he is actively involved in Treadwell & Rollo's sustainability efforts and giving back to the community. As a member of the firm's Green Committee, Josh helped the firm achieve its Green Business certification in 2007. He has also led the firm's participation in the Rebuilding Together organization since 2006.
"Reducing resource and energy usage is a great thing to do at home, and I want to apply it here too," he says.
