Keeping communities healthy and clients happy since 1995

Walden Environmental Engineering was founded with a focus on providing local environmental engineering services. Over the years we’ve maintained our priority to serve the communities in which we live and work, even as the company expands.

That commitment has not gone unnoticed. Walden retains clients from when it opened its doors in 1995, evidence of the company’s excellence in environmental consulting and professional engineering services. As the company grows into new regions and new services, we continue to prioritize technical innovation, a collaborative approach with the customer, and timely response in solving unique environmental challenges.
