Corporate counsel informed by M&A know-how

Mark’s M&A experience is especially valuable to clients in healthcare and other industries experiencing consolidation. His hands-on understanding of the business combination process helps him advise clients on corporate governance and other structures that will best support their long-term objectives. Mark served as the firm’s Managing Partner from 2001 to 2017, an experience that has served him well as an advisor to C-suites and boards of numerous client organizations.

Reading the healthcare tea leaves

In an era of unknowns about the future of the healthcare industry, Mark’s legislative background enables him to provide particular insight. Before joining Schwabe, he was a legislative assistant to Oregon Senator Bob Packwood and a principal of a Washington, D.C.-based federal affairs and governmental relations consulting firm. He continues to monitor and influence public policy in the health care arena through his work on behalf of the Oregon Business Association’s Health Policy Committee.
