Addiction therapists & psychiatrists in Plainfield, IL

Great to meet you! I’m Mario (or Tomario), a Licensed Clinical Social Worker with over 14 years of experience helping individuals, couples, and families through life's toughest challenges. Whether you're navigating career stress, relationship difficulties, family conflicts, depression, or substance use, my goal is to serve as a supportive catalyst for positive change in your life.

Some weight is hard to name. Grief that surfaces unexpectedly. Trauma that won’t stay in the past. Anxiety that makes the present feel unmanageable. Whatever you’re carrying, I’m here to help you make sense of it.

I work with adults and adolescents, navigating trauma, anxiety, depression, grief, and major life transitions, including end-of-life care for individuals and families facing serious illness. With 8 years of experience across criminal justice and clinical social work, I bring a grounded, practical perspective to therapy, one that takes your full story into account, not just the presenting problem.

My approach is client-centered, strengths-based, and collaborative. I believe therapy should be a space where you feel heard, respected, and free from judgment. Together, we can better understand what you’re experiencing, build meaningful coping strategies, and identify practical steps toward healing and greater emotional well-being.

You don’t have to have everything figured out before you begin. Wherever you are in your journey, I’m here to meet you there.

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.

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. Many of my clients are used to juggling responsibilities, caring for others, and pushing through difficult seasons until they realize they're no longer feeling like themselves. 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.

If you're struggling with addiction, carrying the weight of complex trauma, or trying to cope while managing a chronic health condition, I want you to know there's a way forward — and you don't have to walk it alone. I'm a Certified Drug and Alcohol Counselor (CADC) with over 16 years of experience across private practice, residential substance abuse treatment, medical social work, and the non-profit world. I've sat with people in their hardest, most overwhelming moments, and I bring that same steady, non-judgmental presence to every session.

Much of my work centers on substance use and recovery, complex trauma, and the emotional toll of chronic medical conditions. Whether you're in the thick of a crisis or finally ready to address something you've carried for years, I'll meet you exactly where you are — with compassion, real tools, and zero judgment.

I specialize in counseling individuals with addictions, eating disorders, mood disorders, anxiety disorders, and trauma. My goal as a therapist is to help patients live the life they imagine, so please feel free to come in and let me know what you're struggling with, and we will work collaboratively to figure out the best way to move toward healing. I know life can get really challenging at times, symptoms flare up, you feel lost. I'm here to listen to you and work together to help you cope and rebuild the life you want to live.

If you're functioning on the outside but privately exhausted, stuck, or carrying more than you've let on, you're in the right place. I work with adults, many in the LGBTQIA+ community, navigating trauma, grief, relationship strain, and major life transitions. A lot of my clients come in saying, "I know what my patterns are. I just can't seem to change them." That's exactly where we start. Together, we'll get underneath what's keeping you stuck and build a path forward that actually fits your life.

I’m a board-certified Psychiatric Mental Health Nurse Practitioner with a background in nursing leadership and healthcare operations. After serving as a Chief Nursing Officer, I chose to transition into psychiatric care because I wanted to work more directly with individuals and families. I recently completed my PMHNP training and bring experience supporting people across the lifespan, from children through older adults. My areas of focus include anxiety, depression, PTSD, bipolar disorder, schizophrenia, personality disorders, and addiction.
