Patterson + Sheridan, LLP Receives 2022 Mansfield Rule Certification

Patterson & Sheridan, LLP is proud to announce that on Thursday, May 5, 2022, Diversity Lab named Patterson & Sheridan, along with 25 midsize law firms as recipients of the inaugural Midsize Mansfield Rule Certification. This certification is a result of Patterson & Sheridan completing a rigorous 18-month collaboration with Diversity Lab since September 2020 to track, consider, and measure a minimum of 30% diverse candidates for roles and opportunities.

“We are incredibly proud of – and grateful to – the firms that stepped up to try this new version and partner with us to create more diverse and inclusive workplaces in the midsize sector,” said Kate Johnston Ryan, Chief Administrative Officer at Diversity Lab. “Despite launching the midsize iteration of the Mansfield Rule in the midst of a global pandemic, these firms were not deterred from taking on challenging system changes to increase diversity in their firms and the profession. We thank and congratulate this truly committed group of firms and leaders.”

The overall goal of the Midsize Mansfield Rule is to increase diversity in leadership pipelines within midsize law firms by broadening the pool of women lawyers, LGBTQ+ lawyers, lawyers with disability’s, and/or underrepresented racial and ethnic lawyers who are considered for entry-level and lateral attorney job openings, firm governance opportunities , equity partner promotions, and opportunities to connect with clients.

Congratulations to the P+S Diversity & Inclusion committee (Jessie Herrera & Puja Detjen) on their continuous efforts of creating a more diverse legal profession and obtaining this certification on behalf of our firm.
