Our Inclusive Community

McGuireWoods has a history of hiring, developing, promoting and retaining lawyers of color, women and LGBTQ lawyers, and veterans. Continually establishing new initiatives and enhancing existing efforts, we focus on meaningful support for our diverse lawyers in their careers. The firm’s lawyer networks are an example of how we support our attorneys in building communities within the firm.

Leading the Way

Two very active groups are charged with focusing on diversity and inclusion: the Diversity & Inclusion Committee and the Diversity Action Council.

Established in 2006, the Diversity & Inclusion Committee — chaired by Baltimore partner and accomplished trial lawyer Ava Lias-Booker — focuses on identifying, attracting, and retaining diverse talent. The D&I Committee also helps incorporate inclusiveness in our professional development, supports retention through lawyer networks, strengthens our marketing and business development opportunities, mentors diverse lawyers, and ensures the firm is well represented at elite events and conferences.

Our Diversity Action Council, led by Managing Partner J. Tracy Walker IV, is the second leadership committee dedicated to advancing the firm’s strategic D&I goals. Formed in 2013, the DAC holds firm leadership accountable for promotion and development of our diverse attorneys by ensuring all firm resources are effectively deployed to further their careers. Every month, DAC members get together for a rigorous assessment of each department’s progress in advancing the firm’s diversity goals.

Such engagement and accountability, buttressed by tailored programs and training, has resulted in steady progress.

D&I Advances

A key focus of the firm’s strategic plan, diversity and inclusion are essential to how we do business, informing how we recruit, retain, and promote lawyers to serve our clients. Our efforts are also supported by partnerships with clients and community members committed to advancing diversity in the legal profession. Working together, we can build a synergistic whole greater than the sum of its parts. That’s diversity in action.
