Addiction therapists & psychiatrists in McLean, VA

My name is Stephanie O'Neill and I am a Licensed Mental Health Counselor. After many years of working in the nonprofit world, I entered the mental health field to help individuals more closely. I have worked in a community mental health setting and have experience with clients of different ages and diagnoses. I provide a supportive environment to help you gain greater insight, clarity, and encouragement to live the life you want to live. I help troubleshoot the areas of your life where you feel stuck and explore ways you can move forward to live with greater joy and ease. Clients I have worked with report that they feel genuinely cared for, and value the relationship we have formed.

I am a Licensed Professional Counselor offering virtual therapy in Connecticut, New Jersey, Maryland, and Virginia. I hold a Ph.D. in Counseling Education and Supervision and specialize in working with individuals navigating the impact of childhood maltreatment and trauma, including sexual abuse. I also support women living with autoimmune diseases who are managing the emotional and psychological toll of chronic illness.

I've built my practice around a simple but powerful idea: that understanding yourself — really understanding yourself — is one of the most transformative things a person can do. I specialize in supporting people through depression, anxiety, life transitions, substance use, mood disorders, adjustment disorder, and end-of-life concerns. That last one might surprise you. End of life is one of the most profound and underserved areas in mental health, and I consider it an honor to walk alongside people and families navigating that terrain. Across all of my work, I bring an educational lens — I don't just want to help you feel better in the moment, I want to help you understand yourself well enough that you can keep growing long after our sessions end. My approach is grounded in CBT and mindfulness, and it reaches toward something bigger: the full picture of who you are — emotionally, physically, and spiritually.

I believe the most effective care comes from a strong, collaborative partnership. I approach each person as more than a diagnosis, and I value honesty, accountability, and mutual respect in the work we do together. Change is possible—I’ve seen it firsthand—and I’m here to support you in becoming the version of yourself you want to be. My background includes both a Bachelor’s and Master’s in Nursing from Walsh University, and I bring that clinical foundation into thoughtful, individualized care.

I’m a bilingual therapist working with adults navigating anxiety, trauma, grief, and major life transitions. Many of the people I support feel overwhelmed by overthinking, internal pressure, difficulty managing stress, and the uncertainty of what comes next.

In our work together, I focus on helping you make sense of what’s happening internally and develop practical ways to respond to stress and emotions. I integrate cognitive, somatic, and neuroscience-informed approaches to support both emotional and nervous system regulation.

I believe therapy should feel human. It can be structured but still fit your individual needs. I offer a space where you can show up as you are, while also doing meaningful work that leads to real shifts in how you experience and respond to life.

As a Licensed Professional Counselor, I believe prioritizing mental health is key to happiness and stability in life. Seeking help can be one of the hardest parts, so congratulations on taking that step! I’ve been practicing for 10 years, but in the last few years, I have shifted my main focus to clients who are struggling with anxiety, depression, and stress management concerns. I also work with professionals who are looking for a safe place to address concerns that they may not always feel comfortable with sharing in their work environment.

I have over 10 years of experience in a wide variety of clinical settings since obtaining my Master's degree and becoming a licensed clinician. I use a client centered approach that draws from my training in cognitive behavioral therapy, motivational interviewing, dialectical behavioral therapy, exposure and response prevention, and a trauma-informed approach. I have worked with people struggling with addictions, a wide variety of anxiety related difficulties, ADHD, depression, and some bodily focused repetitive behaviors. I also have experience working with couples to address relationship needs.

Challenges shouldn’t just be endured—they should be the catalyst for your breakthrough. My goal is to help you transform life's toughest hurdles into a foundation for lasting resilience and self-discovery, giving you the tools to reclaim your strength and lead a more intentional life.
