Sullivan & Worcester Reaffirms its Commitment to Mansfield Certification for 2024-2025
Boston, MA – Sullivan is proud to announce that our firm is reaffirming its commitment to Mansfield Certification for 2024–2025. Ojen Sirin, the firm’s Chief Marketing & Talent Officer, who oversees the firm’s Mansfield commitment, reiterated the benefits the firm has seen in the past three years. “Since joining the Mansfield Certification process in 2021, we have been working hard to increase the transparency and accessibility of our advancement processes, and to open the door even wider to ensure that all talent at our firm has a transparent, fair and equal opportunity to be considered for leadership roles and activities. This is for the benefit of our talent and our clients.” Data shows that firms that remain committed and accountable to the Mansfield Certification process are making substantial progress in creating inclusive talent practices and diversifying their leadership ranks. “We have experienced positive progress at our firm since we joined Mansfield, and we remain committed to taking measurable actions to ensure that our processes are — and remain — inclusive,” said Sirin.  “We are excited to continue being a part of the Mansfield community, which is now 365+ firms strong — the largest cohort to date.

Sullivan Joins Greater Boston Legal Services Associates Fund Drive for 16th Year
Sullivan & Worcester is proud to announce its participation in the Greater Boston Legal Services (GBLS) Associates Fund Drive for the 16th year in a row. Sullivan associates and counsel have donated over $100,000 to GBLS since the firm began participating in 2008. What Is GBLS? GBLS provides free civil legal services to low-income individuals, families and community groups in the Greater Boston area who otherwise cannot afford to hire and retain an attorney. Last year, GBLS provided free legal assistance to over 11,000 clients, primarily in the areas of Family Law, Housing, Immigration, Employment and Health Law.  Although this number is impressive, GBLS is still regrettably forced to turn away more than 45% of meritorious cases because of staffing and financial constraints. On top of that, GBLS’ funding relies heavily on outside donations – last year more than 20% of GBLS’ funding came from the Boston legal community – including over $640,000 given by Associates and Counsel in the 2023 Associates Drive. Donations to GBLS can be made online here.
