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

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

Great to meet you. As a board-certified Psychiatric Mental Health Nurse Practitioner, I work to create a space where you feel seen, heard, and supported. My approach is warm, holistic, and open-minded, and I believe care works best when it is personalized to your needs, goals, and day-to-day reality.

I support clients navigating anxiety, depression, bipolar disorder, ADHD, PTSD, sleep concerns, OCD, panic, eating concerns, and anger or impulse-related challenges. Whether you are feeling overwhelmed, stuck, or simply ready for things to feel more manageable, my goal is to help you better understand what is going on and build a path forward that feels both realistic and empowering.

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 E. C. Kissner — and if you’re someone who feels accomplished on the outside but stretched thin on the inside, you’re in the right place. Many of the people I work with are navigating burnout, transitions, stress, uncertainty about next steps, or a sense that life’s moving faster than they can keep up with. You want clarity, balance, and a way to turn insight into real-world change, and you want a space that meets you where you are — respectful of your identity, your experiences, and your goals.
