Environmental and Municipal Law From our offices in Pennsylvania, California, and Oregon, we practice as one law firm, holding closely to core values that start with a deep commitment to our clients and to the quality of our work on their behalf. Our practice includes an emphasis on teamwork among our lawyers and with other professionals, and a belief in the application of common sense, uncommon resolve and deep and wide-ranging experience to handle our clients’ legal service needs. Our lawyers are recognized nationally for the depth of their expertise. The diversity of our lawyers strengthens both our ability to evaluate issues confronting our clients and our advocacy on their behalf in multiple settings across the United States. And because every client is a client of the law firm, not of any specific lawyer, every client has the ability to call on any of our lawyers as needed.
