Home TPN Care and Support Centered Around the Patient

A nationwide infusion pharmacy and provider of home TPN, supplies and clinical care.

Devoted to Helping Home TPN Patients

Live Their Best Life

At Nutrishare, we know that TPN is not a choice – but who you choose as your provider is entirely up to you and your family.

 

When Nutrishare first started over 34 years ago, the idea was simple: create a home infusion pharmacy that meets the needs of the patient, not the other way around.

 

Since 1991, we’ve been doing just that. We are the only one in the nation specializing exclusively in home total parenteral nutrition (TPN), shipping life-sustaining formulations and supplies to 50 states nationwide out of our redundant California and Kentucky pharmacies. Beyond that, we’ve built a highly specialized team of board certified nutrition support pharmacists, clinicians, dietitians, and patient support professionals and a support network of patients available to you whenever you need them.

Serving TPN Consumers


For over 34 Years

1970s

The idea for Nutrishare was first born in the 70s when a young IV nutrition pharmacist, Rod Okamoto, was working in the basement of a California medical center. Okamoto noticed the great challenges that home TPN patients faced managing their IV prescriptions – supplies were limited and there were always inventory issues.

A newer therapy, home TPN allowed these patients to receive vital nutrition intravenously through their heart since they could not eat orally. Week after week, one by one, patients came to the pharmacy to pick-up their many bottles of nutrition and infusion supplies. The process was an exhausting, lonely one for home TPN patients. Wanting to help, Rod began personally delivering TPN orders after work. Pretty soon, he was doing it for other patients too.

1991

In 1991, Rod partnered with a fellow pharmacist, Tom Diamantidis, and took the idea full scale and created Nutrishare, the first and only home TPN pharmacy designed entirely around the needs of the patient — 1-to-1 care, choice of supplies and expert clinical care, education and support.

TODAY

We are the only one in the nation specializing exclusively in home total parenteral nutrition (TPN), shipping life-sustaining formulations and supplies to 50 states nationwide out of our redundant California and Kentucky pharmacies. Beyond that, we’ve built a highly specialized team of board certified nutrition support pharmacists, clinicians, dietitians, and patient support professionals and a support network of patients available to you whenever you need them.

As the President and Chief Operating Officer, Stephen leads Nutrishare’s clinical operations, patient experience, and sales and marketing initiatives.

 

With a long history in healthcare, born out of his passion for a purpose-driven career, Stephen was drawn to Nutrishare for the unique opportunity to lead a company that works so closely with patients on their healthcare journeys.

 

Before joining Nutrishare, Stephen was on the healthcare team for McKinsey & Company, a global management consulting firm. Prior to that, Stephen developed care and retention strategies for DaVita, a Fortune 500 provider of dialysis services.

A California native, Austin moved east to attend graduate school at Harvard Business School, where he met his business partner, Stephen. Outside of Nutrishare, Austin and his wife, Laura, stay busy with four kids, spending time outdoors, skiing, boating, hiking, and playing sports.
