IIS Provider Member Success Story

For over a decade, Infinity Infusion Solutions (IIS) has partnered with TwelveStone Health Partners to deliver best-in-class contracting, proactive advocacy, and consistent results in a highly competitive infusion marketplace.

The IIS Difference

Rather than a transactional approach, IIS provides proactive pursuit of optimal agreements, timely communication, and deep understanding of provider economics—ensuring members stay competitive and well-informed.

Results

Despite ongoing competitive pressure, TwelveStone Health Partners has remained a loyal IIS member, benefiting from sustained performance, transparency, and a partnership competitors have been unable to replicate.

"We truly value our relationship with IIS. Aside from the great customer service they provide, we are always impressed with their proactive and timely approach to pursuing the best possible agreements and sharing information with us. We have been working with IIS for over a decade, and during that time there has been a steady stream of competitors that have attempted to convert us unsuccessfully because there just hasn't been anyone in the marketplace that can match the IIS service and results."

Lee Golden, PharmD Chief Clinical Officer TwelveStone Health Partners
