Matthew McNerney joined the Regulatory practice group based out of the Denver office. McNerney specializes in helping clients navigate complex environmental and energy challenges. Drawing on experience in both federal government and private practice, he helps clients navigate regulatory compliance, enforcement matters, and administrative rulemakings by cutting through complexity to find workable, common-sense solutions that balance legal requirements with operational realities. He guides clients through investigations, enforcement proceedings, litigation strategy, settlement negotiations, and rulemaking processes, leveraging deep experience with the Clean Air Act and federal environmental law.

McNerney holds a J.D. from the University of Virginia School of Law and a B.A. in Economics and Business from Colorado College.

Seamus Appel joined the Litigation practice group. Located in the firm’s Salt Lake City office, Appel handles complex commercial litigation, real estate disputes, claims against governmental entities, legal malpractice, and intellectual property matters. He guides clients through every phase of litigation in both state and federal courts and leverages deep mediation and arbitration experience to drive efficient, favorable resolutions. Before joining Michael Best, Appel was an associate at a litigation-focused firm, where he managed all aspects of a variety of commercial litigation matters from the commencement of actions through to trial and appeals. He received his J.D. from Indiana University Maurer School of Law and B.A. in Philosophy, Politics, &amp; Economics from Denison University.
