About the Role

This is a unique role that sits at the intersection of HR operations and growth. As HR Acquisition Integration Analyst, you will be the primary HR lead for integrating newly acquired dental practices into the 123Dentist network, while also supporting employee lifecycle administration and leave management across the organization.

No two integrations are the same. You will review and assess payroll practices, benefit programs, retirement plans, HR policies, and employee data, then build transition plans that set new teams up for success from day one. You will work closely with Operations, Payroll, Mergers and Integrations, Benefits, and clinic leadership to coordinate activity and deliver a positive employee experience throughout the process.

If you are an organized, people-focused HR professional who thrives on complexity, enjoys variety in your day, and wants to play a hands-on role in a growing organization, this role is built for you.
