Insights

Pro Bono Leadership Nossaman ranks highly in pro bono work and has recent top-20 recognition on Law360’s Pro Bono Leaders list, signaling a strong commitment to community service. This presents opportunities to offer collaborative programs or partnerships with public agencies and non-profits seeking pro bono support or policy advisory services aligned with their established culture.

Growth & Hiring Recent hires and expansion activity including adding partner Andrew Vogel and Michele Kirrane to the employment practice indicate ongoing growth in key practice areas and geographic presence. This suggests potential for cross-selling expanded services to existing client networks and targeted outreach to mid-market organizations undergoing expansion projects.

Policy & Lobby Regular recognition as a top lobbying firm by Bloomberg Government and sustained presence in policy-focused practice areas imply strength in government affairs and regulatory landscapes. This creates selling opportunities for clients needing regulatory strategic advisory, government relations, and infrastructure-related guidance.

Industry Focus Specialized practice groups in transportation, healthcare, financial services, real estate, water, and employment position Nossaman as a strategic partner for industry-specific challenges. Targeted outreach to corporations and agencies within these sectors could yield opportunities for bundled or retainer-based advisory across multiple disciplines.
