Bipolar disorder therapists & psychiatrists in Reston, VA

Hello! My name is Danielle Sims and I hold a Master's degree in Mental Health Counseling.I strive to create a welcoming and inclusive space for individuals and families from diverse backgrounds.

I use a variety of therapy models based on our assessment of your needs along with your goals. I am here to help guide you through your journey and provide tools and education to improve your quality of life.

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 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.

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.

I have over eight years of experience working with people from diverse backgrounds in a variety of environments.

I have experience working with first responders, Law Enforcement and military individual. If you are paying out of pocket, please ask me about my sliding scale fees. I look forward to meeting you.

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.
