Walden welcomes Ashley Erdmann to its staff! Ashley joins us as a Project Engineer having recently moved to Long Island from Sebastopol, California. Don’t worry, we didn’t know where that was either and had to look it up. We are pleased to find out that our summer BBQ’s will be featuring fine California wines, as Sebastopol is located near Sonoma and Napa Valleys. Ashley brings her expertise in sustainable wastewater treatment facilities, water quality and groundwater treatment system design, and a passion for recycling to Walden. Please join us in welcoming her to our team!
