William O'Donnell, Jr. (1914 - 1971), Alvin L. Weiss (1926 - ) and Emidio H. Mattei opened their doors as O'Donnell, Weiss & Mattei, P.C. in 1955. OWM Law continues to represent hundreds of clients throughout Southeastern Pennsylvania operating from our original location on 41 High Street in Pottstown, PA, and from our second office at 347 Bridge Street in Phoenixville, PA. From the original three lawyers, the firm has grown to thirteen attorneys and a dedicated staff of paralegals, legal assistants, and a legal administrator. O'Donnell, Weiss & Mattei, P.C. represents individuals and families, small businesses and corporations, municipalities, banks, and charitable organizations, and is committed to providing quality legal representation in the most expert and cost-effective manner. Our success comes from not losing that 'small town feeling' with our approach to clients, and offering skilled legal diversity, a broad range of experience, and over 55 years of successful representation.
