Pituitary Center

About Our Center

Being diagnosed with a pituitary tumor or pituitary disorder probably set many questions racing through your mind. Because pituitary tumors and the diseases they cause are rare, many people have no idea what to expect when they are diagnosed, and they often don’t know where to turn next.

If you’re reading this, you’ve turned to the right place. At the Pituitary Center at Barrow Neurological Institute, our specialists believe that patient education and involvement form a vital foundation for the successful treatment of pituitary tumors and disorders. And, because our doctors and nurses treat more people with pituitary disorders than any other team in the Southwest, you can rest assured that you will be in experienced hands once you decide on a course of treatment.

The Barrow Difference

Mastering the Master Gland: The Most Experienced Center in the Southwest

No other hospital in the Southwest performs more pituitary surgeries on a yearly basis than Barrow Neurological Institute. In fact, 2018 we performed six times as many pituitary procedures as any other hospital in the state. Patients travel from around the country to come to Barrow. Patients who have surgery by an experienced surgeon have better outcomes than patients who have surgery by a surgeon who only performs the surgery a few times a year.

This experience means that our doctors and nurses have seen nearly every kind of pituitary tumor and disorder imaginable. With this exposure, they have gained invaluable insight that helps them be efficient and effective in administering your care.

This graph shows that the pituitary center and barrow neurological institute performs more than twice as many pituitary surgeries than all other hospitals in Arizona combined.

Team Approach

Many pituitary disorders can cause problems in your body far beyond the pituitary gland. Our location at Dignity Health St. Joseph’s—the largest hospital in Arizona—means that Barrow patients also have access to a tremendous array of specialists.

Clinical Trials and Research

Not only is Barrow a place to receive the most advanced treatment and care for your pituitary tumor or disorder, we are also a place where you can help contribute to the scientific understanding and therapeutic research surrounding acromegaly, adenomas, gigantism, and other disorders that implicate the pituitary gland.

Certified Neuroscience Nurses

The experience of our staff doesn’t drop off outside of our neurosurgeons and neurologists. All of our nurses at the Barrow Pituitary Center are required to undergo additional rigorous training in the nuances and complexities of advanced neuroscience nursing practice. This guarantees that whenever you see a Barrow nurse at your bedside, you will know you are receiving expert care.

In fact, many of the surgical treatments and medical protocols used on patients here were researched and developed on site and have spread to many other top hospitals the world over.

All of Your Appointments in One Location

Because there is such a diversity of medical knowledge within minutes of our doors, odds are that you will be able to concentrate all of your necessary care under one roof. At Barrow, we refer to this as having a “medical home.” And, as you would expect with anyplace called home, with it comes convenience, comfort, and compassionate care.

Portrait of Patricia Buckley

Dr. Yuen was able to quickly assess the situation and, over time, has literally given me my life back. He gave me back things that I hadn’t even realized that I was missing out on.

When I went to Barrow and talked to Dr. Little, he made me feel at ease. He then explained the procedure to me which made me feel much better. It was going to be a less-invasive approach than I thought.

Dr. Barranco’s skill, I think, speaks for itself. But the unsung heroes here are the four nurses I had in intensive care. They did more than just follow the doctor’s instructions; they also anticipated what I needed at times when I didn’t even know I needed it.
