With over 30 years in nursing and dual board certification as both a Family Nurse Practitioner (FNP-BC) and a Psychiatric-Mental Health Nurse Practitioner (PMHNP-BC), Tammy Endicott brings a rare combination of whole-health expertise and specialized psychiatric training to her Vienna, VA practice. She has served patients across the full spectrum of life — children, adults, and seniors — and now focuses that depth of experience on the psychiatric and mental health needs of individuals throughout Fairfax County and Northern Virginia.
For 20 years as a family nurse practitioner, Tammy treated the physical and whole-health needs of patients across communities. Her transition into psychiatric-mental health practice built on that foundation — adding specialized expertise in medication management, mood disorders, ADHD, adolescent mental health, and the particular mental health challenges facing military-connected individuals in the Northern Virginia region.
Tammy’s connection to military life isn’t only clinical — it’s deeply personal. She spent 32 years as an active-duty military spouse and raised two military BRATs of her own. She has lived through deployments, reintegrations, frequent moves, and the emotional complexity that military life places on everyone in the household — not just the service member. That lived experience gives her a level of genuine understanding that no training program can replicate, and it is one of the defining strengths of her care for military-connected patients across Northern Virginia.
Today, through Strong Minds PLLC in Vienna, VA, Tammy provides evidencebased psychiatric care that sees patients as whole people — not just diagnoses. She believes in listening first, collaborating always, and building care plans that work within the reality of each patient’s life.
Every recommendation is grounded in current clinical research and psychiatric best practices for the conditions Tammy treats in Vienna and across Northern Virginia.
Strong Minds is a safe space for patients who have felt dismissed, misunderstood, or stigmatized — in other healthcare settings, in traditional psychiatry, or in military medical culture.
Tammy believes her patients are the experts on their own lives. Informed, collaborative care leads to measurably better outcomes.
