Here to protect what matters most

Inside RIS Rx HQ — Irvine, CA.

At our core, Stephen and I are still pharmacists. That means every conversation about leakage is really about patients. Every dollar saved is a dollar that can be redirected to someone who needs their therapy today, not tomorrow.

Gerard Rivera discusses patient financial barriers with two women in a pharmacy setting.

CEO Gerard Rivera as frontline pharmacist prior to RIS Rx's founding.

As frontline pharmacists, Gerard Rivera and Stephen Hom experienced a painful reality at the pharmacy counter every day.

All too often, patients fell victim to a “copay surprise,” learning only at the counter that the medication they thought was fully covered by their affordability program would cost them out-of-pocket. Coverage of a copay sometimes meant the difference between starting therapy or going home empty-handed.

Later, working with pharma executives who managed billion-dollar copay budgets, Gerard and Stephen realized something shocking: the disappointment and confusion they experienced with their patients wasn’t inevitable. Copay funds often vanished into a maze of copay program rules, accumulators, maximizers, and other systemic inefficiencies.

That’s when RIS Rx – and the idea of GTN Revenue Protection – was born.

By marrying the patient experience at the pharmacy counter with the executive view of how programs are designed, RIS Rx found a better way to make sure that every patient and every brand were well served.

Today, RIS Rx is committed to bringing integrity back to affordability by protecting every patient, every dollar, every time.

Affordability isn’t just a financial issue. It’s a clinical one. If a patient can’t afford to start therapy, the medicine never has a chance to help.
