Many of the people I work with come in feeling overwhelmed, stuck, or exhausted from carrying things on their own for too long. It is a true privilege to sit with individuals during some of the most difficult and painful seasons of life. My hope is to create a space where you feel genuinely seen, known, and valued. Through curiosity, compassion, and genuine connection, we can explore your story together, begin healing deep wounds, and move toward greater wholeness and freedom. I’m passionate about helping people make sense of their stories, heal from what has wounded them, and move toward a life that feels more whole and meaningful. Above all, I believe therapy works best when you feel safe, understood, and genuinely supported in the process.
I’m Dr. Sharline Mashack, a board-certified Psychiatric/Mental Health Nurse Practitioner, and I specialize in treating patients with conditions ranging from ADHD to schizophrenia. I use a holistic approach combined with evidence-based practices to develop treatment plans, prescribe medications, and provide psychotherapy.
As a military spouse, I’ve had the opportunity to work in several areas of the healthcare system, learning from experienced leaders along the way. I earned both my Master’s and Doctorate in Nursing.
Challenges shouldn’t just be endured—they should be the catalyst for your breakthrough. My goal is to help you transform life's toughest hurdles into a foundation for lasting resilience and self-discovery, giving you the tools to reclaim your strength and lead a more intentional life.
