Arnie’s clientele spans both for-profit and nonprofit sectors, with significant experience in low-income housing development, complex financing, and private stock placements. His hands-on experience extends to construction law, having worked as a laborer for Bob Vila of This Old House during college, and advising clients on construction contracts, insurance, and dispute avoidance and resolution throughout his career.
I like to get to know my clients well so that I understand not only the opportunities and pressures facing the business, but also what motivates them personally so that I understand and can focus on long term goals. While I have enjoyed all aspects of my work, my greatest pleasure has been to watch and help businesses grow, and then help the owners transition out, whether by a transfer to the family’s next generation, sale to a third party, or sale to employees and management.
