Alliant Insurance Services Appoints New Leadership Amid Growth Surge
Alliant Insurance Services has strengthened its team by appointing Brian Minkler as Senior Vice President in the Employee Benefits Group and Justin Sorensen as Executive Vice President of the Mergers and Acquisitions division. These strategic hires support Alliant's growth trajectory, highlighted by a reported brokerage revenue surge to $5.72 billion in 2025, a 14.4% increase from the previous year. This robust growth elevated Alliant to the position of sixth largest insurance broker by revenue in the U.S., as per Business Insurance's 2026 rankings, while maintaining its stance as the largest private equity-backed brokerage in the country.
Brian Minkler brings over a decade of experience in optimizing human capital and employee benefits strategies, especially for ventures in high-growth phases or backed by venture capital and private equity. His expertise spans compensation and benefits, retirement design, compliance, and workforce management. Minkler's role is crucial as employer health costs continue to climb, prompting businesses to seek refined benefits advisory services. Before joining Alliant, he served in leading roles at a prominent global HR services firm, focusing on benefits and compensation advisory.
Justin Sorensen, based in Chicago, is tasked with delivering strategic risk and insurance solutions within Alliant's M&A vertical. With over 20 years in risk management and insurance, his background encompasses work with Fortune 500 companies and startups alike. His role is vital, particularly for private equity-backed entities requiring comprehensive transactional risk coverage during ownership transitions. Notably, Sorensen's appointment coincides with a dynamic M&A landscape, as evidenced by the 695 U.S. insurance agency transactions recorded in 2025 by OPTIS Partners, predominantly influenced by private equity-backed and hybrid buyers. Headquartered in Newport Beach, California, Alliant continues to expand, with over 100 offices nationwide.
