Of Counsel

Based on his 50-year membership in the Bar, most of which was spent representing hospitals and large physician group practices, Neil shares his experience and thoughts on strategy with other lawyers in the firm. He served on the Management Committee of three law firms each of which had a regional practice. This business experience has enriched Neil’s advice to colleagues and clients in terms of finding practical solutions to their problems.

While representing more than 15 of NH’s 24 hospitals, Neil advised on mergers, affiliations, compliance matters, professional staff relations, Certificate of Need projects, governance issues, regulatory issues and advice to the Senior Executives and Board Officers. Notable cases include:

Personal Qualities

“As a lawyer, I believe the most valuable service I can render to a client is to simplify extremely complicated problems, present a variety of strategic solutions which can be implemented quickly and effectively, and then assist the client in the decision making process. Sifting out what’s important from what isn’t is a joy for me and a benefit to my clients.”
