A Team Defined by Excellence


Gerard V. Mantese, the firm’s CEO, has spent over a decade leading teams of highly skilled attorneys to victory in complex litigation matters. In September 2017, the State Bar of Michigan awarded Mantese its top honor – the Roberts P. Hudson Award – for service to the profession and for his effective legal work. Since 1979, only 42 attorneys in Michigan have received this honor.

David Honigman, a former Michigan State Senator and Representative, spent over a decade in the Michigan Legislature developing a reputation as a popular and highly effective advocate and coalition-builder. Honigman authored more legislation than any other legislator during his tenure, and has been recognized as a Leader in the Law for his tenacity and brilliant advocacy.

MH's other partners bring critical legal experience, scholarship and courtroom wins to the table.

Douglas Toering, the immediate past Chair of the Business Law Section of the State Bar of Michigan, has been a go-to business law attorney for over 30 years and was instrumental in the creation and development of Michigan’s Business Courts. Widely recognized and respected by his peers, Toering has agreed to author a regular column in the Michigan Business Law Journal, "Touring the Business Courts."

Theresamarie Mantese is Chair of the firm’s Health Law department, and is a recognized expert with a broad array of publications on critical issues facing health care professionals. Ian Williamson, one of the firm’s primary business litigators, serves on the Council for the State Bar of Michigan’s Business Law Section, and with Gerard Mantese secured a $30 Million trial win in 2017 in a shareholder oppression case.

MH’s associates and senior attorneys, carefully chosen for their scholastic excellence and dedication, are rising stars and respected practitioners in the legal community. Equally at home in the courtroom or drafting incisive and complex legal briefs, MH attorneys publish scholarly business law articles at a rate unsurpassed by any other firm in Michigan.

Super Lawyers, Martindale Hubbell and Best Lawyers have repeatedly recognized MH’s superb team; and Super Lawyers routinely names Mr. Mantese as one of the Top 100 Lawyers in Michigan.

MH handled the only two shareholder and member oppression cases that have been decided by the Michigan Supreme Court, and the firm succeeded in establishing important rulings cited in hundreds of publications and other cases. See Madugula v Taub, 496 Mich. 685 (2014), (oppression action is equitable, empowering the trial court with wide latitude in resolving shareholder disputes); and Frank v Linkner, 894 N.W.2d 574 (2017) (MCL 450.4515 is a statute of limitations, not of repose; oppressed LLC members may be able to sue even before incurring financial harm; members may toll the statute if there is fraudulent concealment of relevant facts).
