Engage PEO Continues Growth in Missouri

Fort Lauderdale, Fla. – June 3, 2026 – Engage PEO, a leading professional employer organization providing HR outsourcing solutions to small and mid-sized businesses nationwide, today announced that Sean Sullivan has joined the company as vice president of sales, Missouri. Based in St. Louis, Sullivan will help expand Engage’s presence across Missouri and the broader Midwest, working with employers, referral partners and business advisors to bring the company’s PEO services to more organizations throughout the region. 

“Sean has spent his career helping companies grow in competitive markets,” said Jay Starkman, CEO of Engage PEO. “He understands that growth comes from staying responsive, building trust and helping employers solve real problems over time. Missouri continues to be an important market for Engage, and Sean adds another layer of experience to a sales team that is already building strong relationships across the Midwest.” 

“Sean brings a practical, field-tested approach to business development,” said Patrice Alvino, group vice president of sales, Northern Divisions. “He has worked with business owners, CPAs and other referral sources on decisions that take time and trust. That experience will serve him well as Engage continues building relationships across Missouri.” 

Sullivan has more than 17 years of experience across the PEO and technology sectors, with a background in enterprise sales, go-to-market strategy, sales operations and partner development. Throughout his career, he has worked with employers on workforce and operational challenges while building broker, CPA and advisor relationships across competitive markets. 

Prior to joining Engage, Sullivan held senior sales roles with both national and regional organizations, where he drove revenue growth, expanded market share and managed complex enterprise opportunities. His accomplishments include building referral networks, closing major deals in the Midwest PEO market and helping organizations strengthen sales infrastructure to support long-term growth. He was recently named one of the “Top 100 St. Louisans to Know” by St. Louis Business Monthly. 

“I’ve worked with a lot of employers who know they need stronger HR support, but they do not always know what the right structure should look like,” said Sullivan. “That is one of the reasons Engage stood out to me. The company’s high client satisfaction, strong retention and consistently high Net Promoter Scores show that the service commitment continues after the sale. That matters to business owners, and it matters to the referral partners who introduce them.”
