Paul concentrates his practice in the mergers and acquisitions, securities, banking and corporate areas. Paul's practice includes complex and sophisticated transactions and counseling clients on a variety of business matters. While Paul has a significant amount of specialized experience, he has maintained the breadth of practice necessary to effectively lead transactions and client relationships and function as outside general counsel for clients without inside counsel. During his career, Paul’s client base has consisted largely of public companies and large to medium privately-held businesses.

Paul's philosophy is to take a practical, hands on and results-oriented approach to his practice. In addition to paying attention to the details necessary to properly represent his clients, Paul maintains the ability to see the big picture by focusing on the outcome, rather than just the process. While he acts as an effective advocate for his clients' interests, Paul recognizes that the best results often are achieved by taking a collaborative and reasonable, rather than adversarial, approach with other parties and their advisors.

Several years ago, Paul helped develop the firm's guidelines that focus on client service as a leading firm core value and, more recently, he led the firm's Practice Excellence initiative - an ongoing firm-wide effort to constantly increase its capacity to provide excellent service, professional quality and outstanding value to its clients. Paul’s firm responsibilities during his career have included participation and leadership in almost every area of firm management, including management, compensation, opinion, marketing, hiring, practice group and associate review and training.

Paul earned his undergraduate degree from Saint Anselm College (B.A. Business and Economics, summa cum laude, valedictorian) and his law degree from the University of Notre Dame (magna cum laude). He was a partner at Devine, Millimet & Branch in Manchester, New Hampshire prior to joining Barley Snyder as a partner. During his career, Paul has developed a reputation among, and earned the recognition of, his peers as comparing favorably with business attorneys from larger firms. Paul maintains an "AV" Martindale Hubbell rating and has been listed in The Best Lawyers in America (Securities, Corporate and Banking & Finance areas) and in Pennsylvania Super Lawyers (Mergers and Acquisitions).

Paul's experience includes:

  • Mergers and AcquisitionsPaul's experience in the mergers and acquisitions area initially was developed primarily in transactions in the banking industry. During his career, Paul has branched out into other industries in dozens of public and private transactions, many of which have been multi-million dollar, multi-state transactions. These transactions often require coordination of a number of different "moving parts" and various levels of financing.
  • Securities - In the securities area, Paul has built a solid base of knowledge over the years with respect to public company disclosure requirements, including a working knowledge of accounting aspects of securities filings. This knowledge base is valuable to the firm's public clients in both their periodic SEC reports and their capital raising activities.
  • Financing - Paul has established expertise in financings, ranging from conventional bank borrowings to venture capital, private equity and mezzanine financings. In the financing area, Paul's experience representing both lenders and borrowers is valuable in closing transactions.
  • Bank RegulatoryPaul represents large, regional financial institutions and community banks. Paul's knowledge of the financial services industry and his bank regulatory experience allow him to "add value" in his work for institutions in the industry.
  • Business - Paul strives to understand the businesses of his clients and, as a result, often becomes a counselor to, and an adjunct member of, his clients' management team.
