Why Choose Paychex?

Starting out as a small dental consulting firm didn’t stop Kerry and Olivia Straine from setting lofty goals. In fact, they brought on as many services and solutions Paychex offered and continued to add over the years. So, payroll led to HR and then to onboarding, time and attendance, and eventually retirement services. They said such growth and transition proved to be seamless with help from Paychex’s suite of flexible and scalable solutions.
