Fourteen years of clinical practice, five specialties, three languages, and one conviction: people get better when someone takes the time to understand them.

A wider lens than most

Marianna Diloyan is a nurse practitioner with more than 14 years of clinical experience spanning primary care, psychiatry, neurology, cardiology, and gerontology. That breadth is deliberate, and it shapes everything about how she practices.

​

Psychiatric symptoms rarely stay in their lane. Depression can be the first visible sign of a thyroid disorder. Anxiety can trace back to blood sugar swings or perimenopausal hormone shifts. Cognitive complaints can point toward sleep, vascular health, or nutrient deficiency. A clinician who has worked across all of these systems recognizes the pattern faster — and knows what to rule out before settling on a diagnosis.

​

Grounded in research

Alongside her clinical work, Marianna has conducted and coordinated complex clinical trials, contributing to research in dementia and neurodegenerative disease. Working inside the research process leaves a mark on how a clinician reads the literature: with genuine interest in what emerging science offers, and a clear sense of the difference between a promising signal and a proven treatment.

​

That balance defines her practice. She’s willing to consider newer, evidence-informed options — and equally willing to say when the evidence isn’t there yet

Education and training

Marianna completed her Doctor of Nursing Practice at Duquesne University and holds a Psychiatric Mental Health Nurse Practitioner certification, integrating mental health care directly into a whole-person primary care framework.
