Obsessive-compulsive disorder therapists & psychiatrists in Downers Grove, IL

When someone you love is struggling, or when life starts to feel heavier than you can carry on your own, asking for help can feel overwhelming. You do not have to navigate it alone. I work with children, adolescents, adults, and families facing anxiety, behavioral and emotional challenges, life transitions, school related concerns, family conflict, and trauma. Together, we will build on your strengths, develop practical tools, and create meaningful change that helps you or your loved one feel more confident, connected, and supported.

My path to becoming a psychiatric nurse practitioner wasn't just a career choice; it was a personal mission. After watching a loved one navigate the complexities of mental health, I realized how much the right support—or the lack of it—can change the trajectory of a life. Because of this, I’m not just focused on symptoms; I’m focused on you.

I specialize in anxiety, depression, and neurocognitive disorders, providing telehealth care throughout Illinois. I take great pride in my ability to break down complex clinical terms into understandable language, ensuring you never feel left in the dark about your own brain. When I'm not in the "office," I’m usually staying active, cooking, or listening to an educational podcast to stay sharp on the latest in wellness.

Hello, I’m Sherri Larson, an LCPC who is passionate about helping people feel grounded, understood, and supported. I’ve worked with individuals experiencing trauma, anxiety, depression, grief, and relationship difficulties, and I value the resilience people bring to therapy.

I believe therapy should be a safe, supportive space where clients can show up as they are. My approach is warm, holistic, and grounded in building genuine connection while helping clients explore their challenges, strengths, and goals. My background includes case management, program leadership, vocational rehabilitation, and supporting individuals through trauma, life transitions, recovery, and housing or employment-related stress. I work collaboratively with clients to help them feel seen, supported, and empowered toward healing, growth, and lasting change.

I believe that change and growth happen within a safe and secure relationship. I see symptoms as meaningful, often serving a deeper purpose, and I approach them with curiosity and compassion to help you explore what they may be trying to communicate.

Diana Lankenau has a Master of Science in Nursing from Florida State University and Chamberlain University. She has a Bachelor's in nursing from University of Miami. BA in Psychology from Florida International University. She is Board Certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) and Family Nurse Practitioner (FNP-BC).

I am a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) with over a decade of experience in mental health care, supporting individuals across inpatient and outpatient settings. Through my work, I have cared for clients with a wide range of needs, including chronic and severe mental health conditions, and I understand how overwhelming it can feel to navigate symptoms while trying to maintain daily life.

My care philosophy is centered on partnership. Treatment is not about taking over your care, but about working with you to explore your symptoms, goals, and values. Together, we develop a treatment plan that feels respectful, personalized, and empowering. If you have concerns or hesitations about medication, we will discuss all available options openly and thoughtfully, moving at a pace that feels right for you.

I work with individuals experiencing depression, anxiety, trauma, ADHD, bipolar disorder, schizophrenia, OCD, and other mood and thought-related conditions. During the initial session, we focus on understanding your concerns, reviewing your history, and identifying practical steps toward improvement. Care may include psychiatric evaluation, medication management when appropriate, brief psychotherapy, education, and ongoing support.

I believe mental health care should feel supportive, clear, and collaborative—not rushed or overwhelming.

You do not have to face these challenges alone. My role is to help you reduce symptoms, strengthen coping skills, and regain balance so you can function at your best and move forward with confidence and stability.
