Sanford Chandler

Founder and CEO

Hello, and thanks for visiting our website!

I founded Vertex for two reasons: I felt that we could reduce the workload of rehab professionals like you, and simultaneously help improve your organization’s ability to capture every reimbursement dollar available.

Our mission is to deliver easy-to-use, affordable software that can enable you more time to focus on those you serve. Working with organizations like yours is the only thing we do.

Since 1981, our software has evolved from a client payroll system to a robust collection of tools build on our legacy of helping our customers through increasing reimbursement and reducing administrative workload.

We are proud of what we have accomplished, and that our customers continue to reap the benefits. It would be my honor to give you a tour and to learn more about how we can help your organization. Click here to send a message directly to me.

Very best regards,

Sanford Chandler, Founder and CEO
