OWM Law became a Pottstown law firm in 1955 and was founded by William O’Donnell, Jr. (1914 – 1971), Alvin L. Weiss (1926 – ) and Emidio H. Mattei. OWM Law continues to represent hundreds of clients throughout Montgomery County, Chester County and Berks County, operating from our original location at 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 fourteen 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.
