Hi! I’m Alyssa, a board-certified Psychiatric Nurse Practitioner who works with adolescents, young adults, and adults navigating anxiety, depression, ADHD, stress, burnout, and life transitions. I have experience at Columbia University Irving Medical Center and Children’s Hospital of Philadelphia (CHOP) supporting medically complex children and adolescents, which has shaped my compassionate and collaborative approach to care. My goal is to create a comfortable, welcoming space where clients feel heard, supported, and understood.
Dr. Sheryl Campbell-Julien, DNP, PMHNP-BC
Peace Of Mind Nurse Practitioner In Psychiatry PLLC
In an era of "assembly-line" healthcare, Dr. Sheryl Campbell-Julien offers a sophisticated alternative. She understands that mental health care is not one-size-fits-all.
As a board-certified Psychiatric Mental Health Nurse Practitioner, she provides a high-touch, individualized care experience designed for high-functioning professional adults who seek more than just a routine appointment.
Dr. Campbell-Julien specializes in the intersection of clinical precision and personalized care. Whether navigating the complexities of trauma, the weight of burnout, anxiety, depression, ADHD or the nuances of mood disorders, her approach is rooted in quality over volume. Clients benefit from comprehensive psychiatric evaluations and expert medication management that considers the "full picture" of their lives, rather than a list of symptoms.
With a Doctorate from D'Youville College and deep experience in New York's clinical landscape, Dr. Campbell-Julien provides the clinical authority necessary to move clients beyond temporary relief, guiding them towards a sustained state of clarity, balance, emotional resilience and peace of mind.
Anxiety and depression can make everyday life feel exhausting — and finding the right support shouldn't add to that. I'm a Psychiatric Nurse Practitioner practicing via telehealth across New York State, and I genuinely love what I do. My style is collaborative: I'm not here to hand you a prescription and send you on your way. I want to understand your full picture — your history, your goals, what you've tried before — and build a plan that actually fits your life. Care works best when it feels like a partnership, and that's exactly what I aim for. There's no one-size-fits-all when it comes to mental health, and I'll never treat it that way. If you're ready to take the next step — or even just curious about what that might look like — I'd love to connect.
Board-certified Psychiatric-Mental Health Nurse Practitioner (PMHNP-BC) and Family Nurse Practitioner (FNP-BC) Specializes in comprehensive psychiatric evaluations, medication management, and evidence-based psychotherapy for patients across the lifespan. Dedicated to providing compassionate, trauma-informed, and holistic care in both inpatient and outpatient settings.
I am dual board-certified as a Psychiatric Mental Health Nurse Practitioner and Family Nurse Practitioner. After several years of clinical practice, I earned my doctoral degree in 2021. My experience spans both behavioral and family health settings, including hospital-based behavioral health units, partial hospitalization programs, and intensive outpatient care.
I specialize in the diagnosis and treatment of a wide range of mental health conditions, including ADHD, depression, anxiety, bipolar disorder, OCD, panic disorder, and PTSD. My approach is grounded in evidence-based practice and emphasizes holistic, collaborative care.
Together, we will develop a personalized treatment plan tailored to your unique needs, goals, and values through a shared decision-making process.
I am committed to creating a supportive, nonjudgmental environment and to addressing disparities in mental health care. If you’re struggling, you don’t have to go through it alone. I’m here to support you with compassion, expertise, and care.
