Hi, I’m a Board Certified Psychiatric Mental Health Nurse Practitioner. I graduated from Drexel University with my Master's degree in Nursing. I then completed my Post-Graduate Certificate in Psychiatric Mental Health Nurse Practitioner. I have over twenty years of experience working in healthcare. Psych has always been my passion. My experiences encompass working with clients across the life span, including Child and Adolescents, Adult, and Geriatric patient populations. I’ve provided services to clients presenting with many psychiatric disorders, such as Anxiety, Depression, ADHD, Bipolar Disorder, and more. I’m in the belief that mental health wellbeing is a priority. Human beings are resilient. Holistic care is the key to promoting better patient outcomes. Therefore, I believe that with an evidence-based practice treatment plan consisting of psychotherapy and/or a combination of psychotherapy and medication management, one will be able to control their mental health.
I’m a very compassionate, caring, and empathetic person. I strive to provide holistic care and collaborate with my clients to develop a treatment plan that they are comfortable with.
I am Dr. Christie Simon-Waterman, a dually certified Family Nurse Practitioner (FNP-BC) and Psychiatric-Mental Health Nurse Practitioner (PMHNP-BC) with over a decade of experience providing compassionate, evidence-based, and holistic care across the lifespan. My clinical background spans primary care, mental health, and community-based health, allowing me to care for the whole person—mind, body, and spirit.
I earned my nursing education at Coppin State University and completed my doctoral training with a strong focus on health equity, leadership, and integrated care delivery.
In my practice, I specialize in:
My approach is empathetic, collaborative, and trauma-informed. I believe healing happens best when clients feel heard, respected, and empowered. Together, we develop personalized treatment plans that may include therapy, medication management when appropriate, lifestyle interventions, and ongoing support tailored to your goals.
Above all, I am committed to creating a safe, supportive responsive space where clients can build resilience, restore balance, and move forward with confidence and clarity.
As a licensed mental health therapist, I believe prioritising mental health is important for happiness and balance. Taking the first step and seeking help can be the biggest hurdle. I look forward to walking with you on your mental health journey!
You’re juggling a lot—and it’s okay if your brain isn’t cooperating. Between high-stakes exams, lab reports, job applications, and the pressure to maintain a social life, it’s easy to feel like you’re constantly underwater. When procrastination kicks in, your mind races at 2:00 AM, and campus services have a month-long waitlist, the stress can feel insurmountable.
