Diversity

Marshall Dennehey has long been committed to diversity and inclusion with a commitment that starts at the top. Our current Executive Committee members, G. Mark Thompson, Howard P. Dwoskin and Craig S. Hudson, as well as our past leadership, have set the tone on this issue by clearly and consistently emphasizing that a diverse and inclusive environment is intertwined with the success of the firm.

Diversity means more to us than ethnic diversity, and we strive to make our firm a place where ethnic minorities, women, LGBTQ+ individuals, neurodiverse people and those with physical disabilities can succeed. We have long supported the Legal Clinic for the Disabled in Philadelphia, with two of our attorneys serving on its Board of Directors over the last few years. We are constant in our efforts to retain and grow our diverse population as that strengthens our organization. In 2019 we received a Diversity & Inclusion Award from Liberty Mutual Insurance in recognition of these efforts.

Our history of promoting minority attorneys goes back a generation to when Hiliary Holloway became the firm’s first African-American shareholder in 1990. Presently, we have several minority attorneys who hold positions of senior leadership at the firm, including Michael Turner and Kevin Hexstall who are members of our Board of Directors. We actively seek to hire or promote minorities across professional and support staff as well. The directors of our IT and HR Departments are African-American women, and professionals of other ethnic backgrounds serve as managers and supervisors across many administrative departments of the firm.

We have a 10-person Diversity, Equity & Inclusion Committee that has set into place a number of initiatives that assist in both hiring and retaining attorneys of color. We have a mentoring system in place where our minority shareholders reach out to our younger minority associates to provide them with support, counsel and encouragement, that can make a significant difference in their professional progression.

In addition to mentorship, we hold an annual meeting and dinner in our Philadelphia headquarters office for attorneys of color. Attorneys from all of our 20 offices attend this event (virtually during this pandemic) where educational seminars, specifically designed to assist those of color to thrive in a majority environment, are given. These seminars are led by internal and external speakers. The event concludes with a dinner that focuses on camaraderie and making horizontal connections within the greater firm for an added layer of encouragement and support.

Throughout the year there are opportunities for smaller groupings of minority attorneys, based on geography, to get together and meet with each other. Some of these events are attended by the firm’s Executive Committee, which recognizes how important it is for these groups to be able to spend time with firm leadership. The firm also participates in minority job fairs and strives to identify minority attorneys and law students who are interested in litigation careers.

We are proud to support our attorneys’ participation in affinity groups that will further their professional development and growth. Minority attorneys at Marshall Dennehey are members of, and participate in, numerous minority organizations, including the National Bar Association (African-American attorneys), the National Asian Pacific American Bar Association, the National Hispanic Bar Association, the Barristers' Association of Philadelphia (membership primarily made up of African-American attorneys practicing in the Philadelphia region), the South Asian Bar Association of Philadelphia, the Asian American Bar Association of the Delaware Valley (membership is primarily made up of Asian American attorneys practicing in the Philadelphia region), the Hispanic Bar Association of Pennsylvania and the Tampa Bay Hispanic Bar Association. Additionally, minority attorneys serve on minority and diversity committees and subcommittees of various national and local professional organizations.
