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.
I’m a psychiatric nurse practitioner who provides patient-centered care focused on helping you feel more stable and in control of your mental health. I work with individuals experiencing a range of emotional and mental health challenges. I take time to understand your unique situation and create a safe, nonjudgmental space where you feel supported.
I provide compassionate, collaborative care for clients experiencing anxiety, depression, stress, mood concerns, life transitions, and other mental health challenges. My goal is to help you feel heard, supported, and actively involved in your treatment.
My style is warm, practical, and patient-centered. I work with you to better understand what you are experiencing, identify meaningful goals, and create a treatment plan that fits your needs. With my background in both mental health and family practice, I take a whole-person approach to care that supports both emotional well-being and overall wellness.
In my practice, I work with individuals navigating depression, anxiety, insomnia, ADHD, or dementia who are ready for change but may feel uncertain about where to start. Together, we will identify your unique needs, set meaningful goals, and create a personalized plan that supports healing, growth, and long-term well-being. My goal is to help you not just manage symptoms but rediscover balance, resilience, and hope.
As your mental health provider here's what I want you to know about me:
Hi, I'm Dr. William Yu, a board-certified psychiatrist with over 15 years of experience providing medication management and psychotherapy for adults and adolescents. My areas of expertise include depression, anxiety, ADHD, trauma-related conditions, and life transitions.
I’m a psychiatric nurse practitioner offering medication management. At this time I offer virtual sessions, with plans to add in‐person appointments in the near future. My approach is shaped by more than a decade of experience working in women's health as a nurse midwife. During that time, I realized how important it is to offer care that truly sees the whole person and honors their full experience. That background taught me how to sit with people in vulnerable moments, listen without rushing, and support them through real-life transitions with steadiness and compassion.











Headway makes it easy to find support for your mental health — from finding the right provider, to understanding costs, to scheduling with ease.
Finding the right psychiatrist in Wantagh starts with understanding what kind of care you need. Psychiatrists are medical doctors who can diagnose mental health conditions, prescribe medication, and in some cases provide talk therapy. If you're looking for help with anxiety, depression, ADHD, bipolar disorder, or medication management, a psychiatrist may be the right fit. Psychiatric nurse practitioners (PMHNPs) can also prescribe and manage medication and are another option available through Headway.
With many providers practicing across Nassau County and Long Island, narrowing your search can take time. Consider what matters most to you — whether that's a provider who specializes in a specific condition, offers virtual appointments, or practices near Wantagh, Bellmore, Massapequa, or Levittown. Reading a provider's bio can help you understand their approach and decide if they're a good match before you book.
Psychiatry on Long Island can be expensive without insurance. Using your in-network benefits is one of the most reliable ways to lower your out-of-pocket costs. On Headway, you can enter your insurance details to see estimated session costs upfront, and your out-of-pocket expense may be as low as $0 per session. Nationally, Headway partners with over 100 insurance plans, making it easier to find a psychiatrist who is both the right clinical fit and covered by your plan.
