Obsessive-compulsive disorder therapists & psychiatrists in Oak Brook, IL

I'm a board-certified psychiatric-mental health nurse practitioner with over 10+ of experience in the mental health field, and 3 years as a psychiatric mental health nurse practitioner. I founded Isimi Health & Wellness to provide thoughtful, evidence-based psychiatric care rooted in compassion, cultural humility, and a deep respect for the mind-body connection. My clinical background spans across PHP/IOP settings, Outpatient psychiatry, TMS, and telepsychiatry. I’ve worked with diverse populations experiencing anxiety, depression, trauma, mood disorders, and life transitions. Whether you're seeking support for mood instability, clarity around your medication options, or a space to reset and realign, I’m honored to walk alongside you on your wellness journey.

When stress starts to build, it can affect more than just your day-to-day life. It can impact your mood, your energy, and your relationships. I work with adults and couples who are navigating anxiety, depression, workplace stress, and burnout. You might feel constantly overwhelmed, mentally exhausted, or like you can’t fully “turn off” your mind. At the same time, stress can begin to show up in your relationships through miscommunication, distance, or frustration, making it harder to feel connected and supported.

With over 20 years of clinical experience, I bring a compassionate, understanding and results-driven approach to therapy. My education began at Chicago State University where I received bachelor's degree and Jane Addams College of Social Work where I received my masters. I specialize in helping individuals navigate anxiety, depression, mood, and personality disorders with clarity and confidence. Together, we’ll build practical tools and deeper insight so you can feel more in control and live your best life.

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.

My name is Najm Zaman, and I am a Licensed Clinical Social Worker (LCSW) dedicated to helping individuals navigate life’s challenges, heal from trauma, and build lasting resilience.

My professional journey spans over 15 years across clinical practice, healthcare operations, and community leadership. I hold both a Bachelor of Social Work (BSW) and a Master of Social Work (MSW) from Adelphi University. Throughout my career, I have served in diverse roles—from supervising foster care programs to leading community-based non-profit organizations and wellness initiatives. This background allows me to understand my clients not just in isolation, but within the broader context of their environments, families, and communities.

While I work with a wide range of individuals, my primary areas of specialization include:

• Trauma and Stressor-Related Disorders
• Anxiety and Mood Management
• Life Transitions and Identity Development
• Youth, Young Adult, and Family Dynamics

I listen intuitively — 100% judgment free, with unconditional support. In our work together you'll increase confidence and manage stress more effectively.

We'll uncover the root of what's troubling you, explore new perspectives, and shift into healthier thought patterns.

This is done by integrating evidence based and mind-body approaches, which tends to bring clients RELIEF and CLARITY.

I offer a kind, supportive, and nonjudgmental space where you can show up exactly as you are. Many people come to therapy feeling overwhelmed, stuck, anxious, emotionally drained, or unsure how to move forward. You may be dealing with anxiety, depression, stress, life transitions, relationship issues, or simply the weight of trying to hold everything together on your own. My goal is to help you feel safe, heard, and supported as we work through what is weighing on you. Therapy with me is about creating a space where you do not have to have all the answers right away - just a willingness to begin.

I’m a Psychiatric Mental Health Nurse Practitioner (PMHNP) and mom of four with a passion for helping people feel balanced, understood, and supported. I earned my nursing degree from Chamberlain University in Chicago and completed my psychiatric graduate training at the University of Kentucky. I’ve been proudly serving patients as a PMHNP since 2022.

I provide care for children (6+), teens, and adults, including parents, professionals, students, and anyone navigating life transitions or emotional challenges. My focus areas include: ADHD, anxiety & panic, depression, bipolar disorders, trauma & PTSD, emotional dysregulation and impulsivity, sleep issues, and mood and behavior concerns in children/teens.

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.
