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 30 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 48 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.

Home TPN is a journey - one you shouldn't have to go alone.

Our mission has always been a patient-centered one: provide home TPN patients, and their families, everything they need to thrive on home TPN - choice, generous supplies, convenient shipping nationwide, and expert personalized clinical care.

We believe that better clinical outcomes come from better clinical care.

Our History

A Pharmacy Designed Around the Needs of the Patient

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.
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.

Since then, Nutrishare has grown to not only become a leading home TPN pharmacy and supply provider, but also a trusted partner in clinical care and support. Through the company's Nutrishare Neighborhood, we unite fellow home TPN patients with world-renowned, clinical experts and fellow home TPN patients so they're never alone in the journey.

Our Leadership

Friends since they first met in college, Stephen Holbrook and Austin Pulsipher have always lived service-driven lives. Active in their communities since a very young age, Stephen and Austin served as volunteers abroad in college, and have worked in previous leadership roles in healthcare and impact-driven organizations. Today, Stephen and Austin carry on the legacy of Nutrishare as a patient-focused home TPN provider.

Stephen Holbrook


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.
"It's exciting to be a part of a company that builds deep relationships with patients, and helps them live better lives."
-Stephen Holbrook
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.
Like Nutrishare's patients, Stephen has lived all over the US, but now resides close to the company's headquarters in Sacramento, California, with his family.
When he's not taking care of his Nutrishare family, Stephen loves adventures with his wife and young children, and enjoys skiing, hiking, cooking, reading, and sports. Stephen is a graduate of Brigham Young University, and has an M.B.A. from Harvard Business School, where he first met Austin.

Austin Pulsipher


As the President and Chief Financial Officer, Austin oversees the logistics side of Nutrishare's operations — finance, nationwide shipping, human resources, and IT — making sure that the people and systems are in place to ensure the time sensitive delivery of home TPN to Nutrishare's patients.
"I have always wanted a career with purpose, to do good — with Nutrishare, ensuring that our patients get exactly what they need, wherever they are in the US is important to me so they can live a more fulfilled life."
-Austin Pulsipher
Originally a biomedical engineering major, with the plan of going to medical school to become a physician like his father, Austin's career took a different path when he discovered his love of business and finance at Yale where he played for the 2006 Ivy League championship football team.
After transitioning to business, Austin began his career working for mission-driven private investment firms — American Infrastructure Funds investing in transportation, healthcare, and agriculture sectors, and Sidewalk Infrastructure Partners, and Alphabet spinout building next generation infrastructure platforms.
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 their three children, spending time outdoors, skiing, boating, hiking, and playing sports.
