Find a psychiatrist in Chicago, IL — covered by insurance

Hello.

• I’m excited about working together.

I'm a board-certified Psychiatric Mental Health Nurse Practitioner with experience assessing and treating a broad range of psychiatric conditions. I see patients from young adults through older adulthood. My practice is largely focused on adults dealing with stress, mood changes, sleep issues, and the cumulative weight of work, relationships, and responsibility, and questions of spirituality. I respect your time, your autonomy, and your intelligence.

I seek to provide culturally affirming, holistic care that integrates the mind, body, and spirit. As a multicultural, neurodivergent psychiatrist and daughter of immigrants raised in Chicago, I bring both clinical training and lived experience to our work together. My own journey through burnout and the process of learning to slow down and listen to what my body needed has also shaped the care I provide. It has grounded me in genuine curiosity, humility, and a deep respect for the wisdom you already carry.

I believe mental health care works best when it is collaborative, respectful, and personalized.

Hi, I’m Gretchen, a board-certified Psychiatric-Mental Health Nurse Practitioner (PMHNP, ANCC) with a Master of Science in Nursing from Lewis University. I work with individuals, teens, and families navigating anxiety, depression, trauma/PTSD, ADHD, and substance use concerns, providing care in both English and Spanish. I bring experience from emergency departments, inpatient units, outpatient clinics, and private practice, and I strive to create a safe, judgment-free space where clients feel heard, respected, and supported. I value collaboration and flexibility, tailoring each session to your needs so you can feel empowered to make meaningful changes.

I don't start by asking, "What's wrong with you?" I start by asking, "Help me understand you."

I provide comprehensive psychiatric evaluations, medication management, and psychotherapy for individuals across the lifespan, with a special focus on children, adolescents, and young adults. Whether you're navigating ADHD, anxiety, depression, or a significant life transition, my goal is to provide thoughtful, individualized care in a calm, welcoming environment where you feel genuinely heard, respected, and understood.

I'm a board-certified Psychiatric-Mental Health Nurse Practitioner (PMHNP) with a strong passion for helping adults navigate mental health challenges with clarity and confidence. I earned my Master of Science in Nursing from Maryville University, where I specialized in psychiatric care across the lifespan.

My clinical approach is collaborative, warm, and rooted in evidence-based practices. I provide medication management and integrate psychoeducation to help clients better understand and manage symptoms related to anxiety, depression, OCD, ADHD, and trauma-related conditions. I believe in treating the whole person—not just the diagnosis—and in creating a safe, nonjudgmental space where you feel genuinely heard.

I currently see clients via telehealth only, offering flexible and convenient access to care from the comfort of your own space. Whether you're seeking your first psychiatric evaluation or continued support, my goal is to work with you to create a personalized treatment plan that supports your mental and emotional well-being.

Mental health has been an important part of my journey from the very beginning. I graduated from the University of St. Francis while working in inpatient behavioral health, where I learned how meaningful it is to meet people with kindness, patience, and understanding during difficult moments. I spent time working in medical-surgical settings to broaden my experience, but I was drawn back to mental health because it’s where I feel most connected to my work.

I provide care through telehealth and aim to make virtual visits feel as comfortable and easy as possible. I know it can take time to feel at ease talking through a screen, and I focus on creating a space that feels supportive, relaxed, and judgment-free. I take a collaborative approach, listening closely and working with you to find treatment options that fit your needs and your life.

I work with children, adolescents, and adults experiencing anxiety, depression, ADHD, OCD, mood disorders, and related concerns. My goal is for you to feel heard, respected, and supported as we work together toward feeling better and more balanced in your day-to-day life.

I'm a psychiatric nurse practitioner with several years of experience, now building my own private practice so I can give each person the focused, personalized care they deserve. I work with people navigating anxiety, depression, and PTSD — conditions that can feel isolating, but often respond well to the right support and the right provider. I offer telehealth appointments, including evenings and weekends, so getting care fits into your life rather than the other way around. Whether you're looking for medication management, ongoing mental health support, or simply a place to start, I'm here to walk alongside you every step of the way.
