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.

I am a board-certified Nurse Practitioner with training in both primary care and psychiatric mental health. I have extensive experience providing care in community, correctional, and integrated care settings, where I work with individuals managing anxiety, depression, mood disorders, trauma-related conditions, and other mental health concerns.

I strive to create a supportive, nonjudgmental space where clients feel heard and respected. I value thoughtful assessment, clear communication, and collaborative decision-making to help clients better understand their symptoms and treatment options. My goal is to partner with each client to develop a personalized care plan that supports both mental and overall well-being.

I help to create a safe, collaborative space where you will feel seen, not judged. Our relationship is one where you can let your guard down and show up as your full self. It is my goal to use a warm and compassionate relationship to walk alongside you, offering reflection, compassion, and challenge when needed to help you reach your goals.

As a Doctor of Nursing Practice (DNP) and a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP), I am passionate about providing compassionate, evidence-based care tailored to each individual’s unique needs. I work with children, adolescents, and adults navigating challenges such as anxiety, depression, bipolar disorder, ADHD, autism spectrum disorders, and other mood or stress-related conditions. In addition to these focus areas, I also support clients dealing with trauma, grief, panic disorders, OCD, relationship and family issues, maternal mental health, and cultural or identity-related stressors.

Fluent in English, Hindi, and Punjabi, I value inclusivity and cultural understanding in my work. My goal is to make clients feel truly seen, heard, and supported as they take steps toward emotional well-being and resilience.

Hi, I’m Hayley Johnson, MSN, PMHNP-BC. I am a board-certified Psychiatric Mental Health Nurse Practitioner with over 16 years of experience in nursing, including medical, rehabilitation, home health, and behavioral health settings.

I work with adolescents and adults (ages 12+) experiencing anxiety, depression, ADHD, mood disorders, and stress-related conditions. Many of my clients are high-functioning individuals who feel overwhelmed internally, struggle with focus or emotional regulation, or feel stuck despite trying to manage things on their own.

My background in both medical and psychiatric care allows me to take a comprehensive approach. I consider the full picture, including medical history, lifestyle factors, and when appropriate, possible contributors such as thyroid imbalance, vitamin deficiencies, or hormonal changes.

I am committed to providing thoughtful, structured, and evidence-based psychiatric medication management in a way that feels collaborative and respectful.

Clients should know that I am committed to providing a safe, supportive, and judgment-free space where they can openly discuss their concerns. I understand that seeking mental health treatment can be difficult, and I strive to build trusting relationships through empathy, respect, and active listening.

As a Psychiatric Mental Health Nurse Practitioner, I believe in treating the whole person rather than just symptoms. I work collaboratively with clients to develop individualized treatment plans that align with their goals, values, and lifestyle. My approach combines evidence-based medication management with education, supportive therapy, and practical coping strategies to promote lasting wellness.

Clients can expect me to be compassionate, approachable, and dedicated to helping them navigate life's challenges while empowering them to take an active role in their mental health journey.
