Steve Snow
Principal, Virtual Access Enroll
Steve is a Principal with Virtual Access, a local benefits enrollment firm dedicated to helping small businesses provide best-in-class employee benefits with guaranteed-issue solutions. We specialize in making high-quality supplemental benefits accessible—without the traditional underwriting barriers.
The guaranteed-issue offerings allow employees to access valuable protection regardless of health history, giving employers a powerful tool to enhance their overall benefits package while supporting employee financial wellness.
What sets Virtual Access apart is our hands-on, onsite education and enrollment approach. We meet directly with employees to clearly explain how each benefit works and how it integrates with their existing workplace coverage and personal insurance plans, empowering employees to make informed, confident decisions.
Our mission is simple: deliver comprehensive, easy-to-understand benefits solutions that strengthen businesses, protect employees, and create long-term value for both.
Steve has a BS from Springfield College in Interdisciplinary Studies with concentrations in business and psychology.
