Kerwin Medical Center was founded by Diana Kerwin, MD, as a clinical research site dedicated to improving treatment options for Alzheimer’s disease and other dementias until a cure is discovered.

We recognize the uncertainty and impact that neurological disorders can have on an individual and family, and from that recognition emerged a guiding principal – our patients are family. We view our ability to serve and care for patients as a privilege, and our goal is to be a resource to everyone involved in the life and support of those diagnosed with a dementia, movement disorder or other neurological disorder. Our staff is dedicated to patient and family education, community outreach, and delivering the best possible opportunity for treatment within clinical research.

“We work everyday to help patients with Alzheimer’s disease and other neurologic diseases of aging. Our Center is dedicated to bringing promising clinical trials to patients and families in the DFW Metroplex to participate in finding better therapies and treatments for neurodegenerative diseases. We will not stop until we help to find the cure.”
