Nathan Viehl advises both buyers and sellers in a wide range of sophisticated M&A transactions, including acquisitions, divestitures, financings and leveraged buyouts.

Nathan has extensive experience assisting middle-market startups, private equity-backed portfolio companies and other high-growth companies throughout their life cycle. He brings parties together, develops financing strategies and closes deals. Clients know that Nathan will advise them based on a deep understanding of capital markets, their best options and their industry. He also represents both public and private companies as outside general counsel in a variety of matters.

With a national practice encompassing a wide variety of M&A-related transactions, Nathan counsels clients in diverse industries such as emerging technology, software, health care, higher education and others. While highly adept at assisting with traditional transaction financings—including private equity, venture capital and other traditional sources—Nathan also enjoys the creativity required by less traditional “direct” or “independent sponsor led” transactions. Advising in this market requires flexibility and creativity, traits integral to Nathan’s style of practice.

Nathan’s clients also rely on his deep M&A and financial market knowledge to guide them through changing economic times, such as interest rate fluctuations, which often require out-of-the-box thinking on deal structures. Nathan writes and speaks extensively on these topics including a feature in the American Bar Association’s Deal Points newsletter on the evolving landscape of private equity.
