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.”

Tish LoCascio Yoxall is a Registered Nurse and has worked with Dr. Kerwin as a Study Coordinator and Research Nurse since 2015. Prior to her career in research, Tish worked as an ICU Nurse for nearly 10 years at Zale-Lipshy Hospital in the Neuro ICU. While working at Zale-Lipshy, Tish and her husband became the proud parents of three incredible children, and she decided to retire from nursing to completely dedicate herself to her children and family.

During this time, Tish experienced the impact an Alzheimer’s diagnosis can have on a family as her sister-in-law, mother of three, suffers from early onset Alzheimer’s disease. Prompted by her love for her sister-in-law, an opportunity from Dr. Kerwin, and her strong desire to help find a cure for Alzheimer’s, Tish returned to nursing and joined Dr. Kerwin’s team in 2015.

Tish’s passion for the daily challenge of finding a cure arises directly from her love for her sister-in-law, and others in similar circumstance.  Thus, Tish brings her passion, her nursing skills, and her compassion for KMC’s patients to work every day with the sincere hope of beating Alzheimer’s.

Her sister-in-law is currently in her early 50’s and the final stages of this dreadful fight.
