Mark Heimlich provides clients with hands-on advice in key transactions. He has closed more than 100 mergers and acquisitions, 300 venture capital financings, 30 private equity fund formations, and many joint ventures.

Noted for his negotiating skills, Mark takes a leading, active role in virtually all aspects of every transaction. Prior to law school, Mark worked as a CPA in Deloitte Haskins & Sells' New York office. Applying his experience with Deloitte, Mark resolves road blocks while providing practical legal and business solutions.

Mark takes the initiative in learning his clients' strategies and business in order to customize a deal structure, identify key deal points, and detect and break down complex legal and deal issues. Mark increased the net sales price for a few of his clients by millions of dollars by simply structuring the working capital adjustment at the term sheet stage to exclude deferred revenue.

Mark represents companies across many different industries, with an emphasis on technology, energy, engineering, healthcare, and life sciences. His clients range from technology startups to Fortune 500 companies, as well as private equity and venture capital firms and family offices.

In addition to leading legal teams for issuers in several initial and follow-on public offerings, Mark assists publicly and privately held clients in formation and capitalization, executive compensation and employment agreements, equity incentive plans, joint ventures, and other corporate work.

Mark writes and lectures on current topics regarding fund formation, M&A, securities law, and venture capital. He has spoken in many distinguished forums, including the 3rd Annual Private Equity Conference, where he gave a CLE presentation on fund formations; lectures on M&A and Sarbanes-Oxley at the National Business Institute; and appearances at the Colorado Venture Forum and CFO Forum, where he discussed private equity developments.

"He is absolutely outstanding, and by far our number one choice for a corporate attorney. He devotes complete focus and attention to the transactions that he is working on, and is very experienced and extremely diligent in high pressure situations — as a result, I have more confidence in the quality and completeness of his advice than I do in that of any other senior attorney. He uses more junior resources as appropriate, but it is truly impressive how much he's always on top of the issues, and able to jump in with top notch advice and analysis when needed. His thoughtfulness and focus make a truly important difference in the outcome of deals — other senior attorneys might have under-analyzed similar situations."
