About Us

643 Insurance

What makes 643 Insurance unique in the industry? We’re glad you asked!

643 is a baseball/softball reference to a double play. 643 also refers to the fact that Jonathan and Jessica work together for a “double play” to protect the things that matter most to our clients. When Jonathan and Jessica were thinking about a name for their insurance agency, it was natural to combine their passion for softball and insurance for the agency’s name. 

We are glad that you found us, and we hope that you allow us the opportunity to show you how we help our clients with their insurance needs.

Experienced Independent Agents

Jonathan Gephart

Jonathan Gephart

Jonathan has a BA in Business Management from University of Phoenix. Jonathan started out in the insurance industry in 2012 as a captive insurance agent. He learned that to properly take care of clients, he needed options available when rates increase or if a client prefers to work with a different insurance carrier. He partnered with an existing agency and became an independent agency owner in 2016 and had success with helping his clients from then until 2021. In 2021, Jonathan and Jessica started 643 Insurance because they realized that in order to truly help our clients properly and to keep clients for life, things needed to be done better.

Jonathan has a passion for softball and for giving back to the community by not only teaching girls the fundamentals of softball, but also teaching the valuable life lessons that go along with playing competitive sports. Jonathan has been coaching for the last 6 years and has been successful in leading some of the best teams in their respective age divisions in the state of Arizona during that time. Jonathan coaches two teams (12u and 14u) for the Team Hustle Arizona Fastpitch club.
