Obsessive-compulsive disorder therapists & psychiatrists in Manassas, VA

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.

Whether we are healing old wounds, addressing current struggles, or pursuing increased life satisfaction, therapy can be a useful tool in reaching our goals. Research has shown the best predictor of positive outcomes is the quality of the relationship between the client and therapist. I strive to develop genuine, honest, and collaborative relationships with each of my clients. Whatever the issue, I believe everyone is capable of healing and growth, and I endeavor to help my clients achieve those outcomes.

I am a Board-Certified Psychiatrist and I have been treating patients across the lifespan for over 15 years. Once my caseload became full in 2022, I founded a small practice (Tandem Telehealth) where I now oversee a handful of talented psychiatric nurse practitioners and talk therapists. The team approach allows us to provide faster access to care for new patients and a higher level of support than you would likely receive from individuals working independently.

I am a certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) with several years of experience treating children, adolescents, and adults. I specialize in a wide range of treatment areas including depression, anxiety, autism, oppositional defiant disorder, post-traumatic stress disorder, bipolar disorder and schizophrenia. I have worked in several different settings and enjoy providing care through telehealth, which offers access to quality care when it is needed.

I specialize in treating obsessive–compulsive disorder (OCD) and anxiety disorders, including complex OCD subtypes like HOCD, POCD, SO-OCD, and ROCD. I am a college professor in addition to having a private practice. I have trained hundreds of doctoral candidates in the diagnosis and treatment of anxiety and OCD.

I work with adults, teens, and college students experiencing panic attacks, generalized anxiety, health anxiety, phobias, and intrusive thoughts. I also treat related concerns like tics, insomnia, and anxiety related to tinnitus.

In addition to my clinical focus on OCD and anxiety, I frequently work with men at every stage of life on issues related to identity, career, and relationships. I have years of experience working with college students and with LGB people and their families.

Welcome!! I’m glad you’re here and ready to take this step toward your wellbeing.

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.
