Red Chip works in partnership with Hemophilia Treatment Centers to help build, maintain, and grow outpatient factor programs.

Management Team

We are more than a specialty pharmacy, and we never compete with your HTC.

Our team designs and operates outpatient programs for federally-designated HTCs that offer 340B products to their patients.

Red Chip Enterprises was conceived by Mary Ann Barth and Steve Yamaguchi with Michael Tront in 1993. Today, Mary Ann and Steve continue to apply their 50-plus years of combined expertise serving and supporting the hemophilia community.

After establishing and building a successful publicly-traded homecare company, (Quantum Health Resources) Mary Ann and Steve used their expertise to create a unique model to partner with HTCs and help them grow a profitable 340B program. Together they offer a wealth of experience and knowledge in the complex world of 340B Management.
