John Mutchler + Scott Garosshen Presented with Esteemed Diversity Awards

Intellectual Property + Technology group partner John Mutchler and Appellate group lawyer Scott Garosshen were presented with the Lawyers Collaborative for Diversity’s (LCD) highest honors at the organization’s annual “Edwin Archer Randolph Diversity Award Celebration” on May 26, 2026. John was awarded the 2026 Edwin Archer Randolph Award, which honors the legacy of Edwin Archer Randolph, the first lawyer of color admitted to the Connecticut Bar in 1880. The honor is in recognition of his sustained and deeply personal commitment to advancing diversity, equity, and inclusion within the legal profession. Through leadership roles with the Lawyers Collaborative for Diversity (LCD) and the South Asian Bar Association of Connecticut (SABAC), as well as national service with the South Asian Bar Association of North America (SABA NA), John has paired strategic governance with hands‑on mentorship that has directly shaped the careers of law students and attorneys of color. His consistent advocacy, financial and institutional support of affinity bar organizations, and willingness to use his influence to ensure diverse voices are not only present but empowered have resulted in measurable recruitment, retention, and advancement outcomes across Connecticut’s legal community. John has been a member of LCD since 2018 and served on its Board of Directors from 2021-2023, and as Treasurer from 2024-2026 and is LCD’s President-elect. He has also been a SABAC member since 2017 and has been a member of its Board of Directors since 2021 and has served as Treasurer since 2022. Lastly, John is also a Trustee of the SABA NA Foundation. Scott was recognized as the 2026 Carolyn Golden Hebsgaard Award recipient, which honors Carolyn Golden Hebsgaard, the founding executive director of LCD, who spearheaded initiatives designed to identify, recruit, advance, and retain young attorneys of color in the Connecticut legal profession. Scott’s recognition marks them as an individual who embodies the spirit of the award due to the early distinction they have attained within their first 10 years of legal practice and a demonstrated commitment to developing diverse young lawyers and law students in Connecticut’s legal community. They have sought to leverage their leadership roles in the Connecticut Bar Association (CBA) to nurture the professional growth of underrepresented attorneys and build spaces welcoming to new members from diverse backgrounds. Their leadership and service have been recognized through honors including selection as a Rising Star at the 2025 New England Legal Awards. They have been a member of the CBA since 2019, serving in leadership positions including Co-Chair of the Appellate Advocacy Section, Chair of the Litigation Section, Co-Director of Civics Education for the Young Lawyers Section, and Co-Director of the Civics Education Committee. They are also a former Vice President and Committee Chair of Civics First, and currently serve on the Connecticut Supreme Court Historical Society Board of Directors.
