About Us

The work by scientists and physicians at Banner Sun Health Research Institute (BSHRI) has had a significant impact on generating groundbreaking research, developing effective treatments and devising strategies for prevention of many diseases.

BSHRI, together with its Arizona consortium partners, has been designated by the National Institutes of Health as one of just 31 Alzheimer’s Disease Centers in the nation. In addition, the first state-sponsored Arizona Parkinson’s Disease Center was established at Banner Sun Health Research Institute. We are also home to The Center for Healthy Aging, which explores the multiple factors contributing to healthy aging to enhance the quality of life for older adults.

Being diagnosed with a memory or movement disorder is difficult for both patients and their loved ones. The Cleo Roberts Memory and Movements Disorders Center, located on the campus of Banner Sun Health Research Institute, provides compassionate and state-of-the-art care. The clinic makes available, when possible, all ongoing studies and investigational medications in the field of Alzheimer's and Parkinson’s disease. In addition, we provide support for the community through our lectures and support groups.

We help train the next generation of researchers through our summer and school-year internships. Banner Sun Health Institute contributes to research around the nation through its Brain and Body Donation Program, in which local residents donate their tissue upon death to science. More than 1,600 local residents have donated their brain or tissue through the program.

Social Work

Social Worker, Banner Alzheimers Institute
I believe in individualized patient and family centered care. My approach to care is to offer an empathic care experience to equip people and their families living with a chronic, progressive neurodegenerative disease with critical, education, support, counseling and resources necessary to live a more satisfying and successful, quality of life.

Christine Belden, PsyD


Psychologist, Cleo Roberts Center
I am proud and fortunate to work in a setting that allows her to utilize clinical acumen to aid in diagnosis and optimize and extend independence, while also contributing to promising research to better detect and treat - and one day - cure Alzheimer's and Parkinson's disease.

Debra Witthar, DNP


Nurse Practitioner (NP), Cleo Roberts Center
I value my patient and their families input and strive to work as a team when creating the plan of care. As a daughter of a Parkinson’s patient, I often tell patients, “I intend to work hard and provide excellent care for you, just as I would for my own Father”. I feel that when patients understand the personal implications Parkinson’s has in my own life, they appreciate my honesty and commitment to their care. I feel it is important to utilize a team approach to movement disorders, thus ensuring the needs of the patient are met. My dedication to research fulfills my desire to bring about new and innovative treatments to improve the quality of life for my patients.
