If you’re the one everyone depends on but you feel anxious, burned out, or emotionally drained, you don’t have to keep pushing through alone. I work with adults who are high-functioning on the outside but overwhelmed on the inside, especially women, professionals, parents, caregivers, and veterans navigating anxiety, depression, trauma, ADHD, burnout, and major life transitions.
I’m a board-certified Psychiatric Mental Health Nurse Practitioner with a Master of Science in Nursing (MSN) and over 20 years of experience across diverse healthcare settings. As a veteran, I bring personal understanding of military culture and chronic stress. My approach is collaborative, culturally responsive, and judgment-free, blending evidence-based medication management with supportive, real-world conversation.
If you’re looking for care that feels thoughtful, respectful, and tailored to your life, not rushed or one-size-fits-all, invite you to schedule a consultation and take the first step toward feeling more grounded and supported.
