Powerful corporations sometimes trample the rights of individuals and smaller businesses. Litigation is often the only avenue to compensate victims of corporate wrongdoing. For over 45 years, we have fought corporate abuse, pursuing litigation on behalf of affected individuals, whistleblowers, public entities and other institutions in cases that have raised challenging, significant and at times, novel issues.  We hold large corporations accountable for their actions even though they often have significantly more resources than those damaged by their misconduct. One way this is accomplished is by bringing large numbers of plaintiffs together in a single class to enhance their ability to litigate effectively.

One of the premier firms in the country handling major complex plaintiff-side litigation, Cohen Milstein has over 100 attorneys in offices in Washington, DC, New York, Philadelphia, Boston, Chicago, Minneapolis, Palm Beach Gardens, and Raleigh. We litigate primarily in these areas:

Our firm has earned its international reputation by winning complex cases that others did not want to handle. We have litigated numerous groundbreaking cases, resulting in landmark decisions on previously untried issues involving antitrust, securities, consumer rights, civil rights and other far-reaching matters.

Diversity & Inclusion

Return to Top

Cohen Milstein Sellers & Toll PLLC is committed to a diverse workplace. We view diversity as an inclusive concept that encompasses, without limitation, race, color, ethnicity, gender and gender identity, nationality, religion, age, disability, and sexual orientation. We believe that diversity enhances the quality of our work and the service we provide, and makes our firm a more vibrant and fulfilling place to work. Our commitment is to recruit, train, promote and retain talented attorneys and staff from a wide range of backgrounds.

We are proud that, over the past decade, our efforts in the community and inside the firm have been recognized by the National Bar Association and The National Law Journal. Similarly, the NAACP and Chambers & Partners, among others have recognized our attorneys with their respective “Foot Soldier in the Sand” and “Outstanding Contribution to the Community in Advancing Diversity” awards.

With a long history of advocating for gender equality in the workplace, Cohen Milstein is proud to be recognized for creating a culture of equality and diversity within the firm. In its 2022 Glass Ceiling ReportLaw360 ranked Cohen Milstein No. 8 in the nation (firms with 101-250 attorneys) for exceeding industry averages of female attorneys and No. 2 for the number of female equity partners. Law360 has also repeatedly recognized Cohen Milstein (2022, 2019, 2017, and 2015) as a “Ceiling Smasher” in the legal industry.

To ensure we maintain a diverse workplace, the firm is guided by its diversity policy and an active Hiring and Diversity Committee that reviews all aspects of our hiring, retention, and promotion practices. Kalpana Kotagal, chairs our Hiring and Diversity Committee and works closely with Human Resources staff and firm leadership to advance diversity and inclusion in the workplace.

We have developed multiple ways to advance our Diversity & Inclusion goals:

  • Recruiting: We post job announcements with organizations such as American Constitution Society, American Association for Justice, National Association for Law Placement, and others with diverse memberships and advertise such announcements at law schools with a high percentage of lawyers of color among their alumni. We specifically encourage applicants from diverse backgrounds to apply. Because of these and other efforts, we routinely fill 20 to 40 percent of our summer associate class with candidates of color.
  • Mentorship & Training:  We have a formal mentorship program, whereby one partner is assigned to one or more associates to provide career development guidance to help ensure that their mentees thrive, professionally. Similarly, our Summer Associate and Fellowship programs involve informal and formal mentoring initiatives. We also conduct internal, firm-wide diversity and awareness training to prevent unintentional situations that could cause discomfort to minorities and women.
  • Leadership: Eight of the firm’s 10 practice groups are led or co-led by female partners, including women of color. The firm’s Executive Committee, which consists of five partners, includes two female partners, one of whom is a woman of color. Furthermore, the firm has multiple internal management committees, including the Compensation Committee, Hiring and Diversity Committee, and others – all include female partners, LGBTQ partners, and partners of color – in order to best reflect the current makeup of the firm and its future growth and staffing objectives.
  • Thought Leadership: Our attorneys are nationally recognized thought-leaders in diversity, equity, and inclusion (DE&I) – across industry, including the law.

For example:

  • Kalpana Kotagal, chair of the firm’s Hiring and Diversity Committee, is one of the nation’s leading voices on how industry can implement DE&I initiatives. She is the co-author of the "Inclusion Rider," a ground-breaking hiring contract provision that facilitates diversity in hiring best-practices. Originally created to address the gap in diversity hiring in Hollywood, it can be used in most all industries. Oscar-winning actress Frances McDormand made the Inclusion Rider famous by referencing it in her 2018 Best Actress acceptance speech. It is now used by Warner Bros. and Hollywood luminaries such as Michael B. Jordan and others.
  • Betsy Miller, chair of the Public Client practice, speaks and publishes nationally on cultivating leadership and accelerating systemic change in the legal profession.  For more than a decade, Ms. Miller served as the chair of the firm’s Annual Evaluation Committee, where she reshaped the firm’s attorney review process and approach to bilateral feedback.  As a member of Georgetown Law’s adjunct faculty, she teaches courses on conflict resolution and effective communication.  Betsy is also a certified leadership coach and works with our attorneys on an individual basis to achieve their full potential.
  • Julie Goldsmith Reiser, co-chair of the Securities Litigation practice, is pioneering the use of shareholder derivative lawsuits to hold corporate boards accountable for failing to prevent systemic discrimination, harassment, and retaliation in the workplace. Two of these lawsuits alone have generated more than $400 million in financial relief and have established groundbreaking corporate governance reforms to improve board oversight in addressing these issues, while eliminating practices that have silenced victims, such as mandatory arbitration clauses, and instituting sweeping diversity, equity, and inclusion initiatives.
  • Sharon K. Robertson, a member of firm's Executive Committee, Professional Development and Mentoring Committee, and the Diversity Committee, is spearheading the firm’s legal efforts in cutting-edge and industry-defining pay-for-delay pharmaceutical antitrust lawsuits and generic price-fixing lawsuits. An accomplished trial lawyer, Ms. Robertson has been recognized as one of a few female litigators in the nation to secure court-appointed leadership roles in high-profile MDLs. She is leveraging her experiences in addressing issues of diversity in MDL leadership nationwide including by assisting the James F. Humphreys Complex Litigation Center of George Washington Law School develop "Guidelines and Best Practices for Judges Appointing Lawyers to Leadership Positions in MDL and Class Action Litigation."
