Obsessive-compulsive disorder therapists & psychiatrists in Grand Rapids, MI

I’m a board-certified Psychiatric Mental Health Nurse Practitioner with over 13 years of experience in behavioral health, including more than a decade as a psychiatric registered nurse. I earned my post-master’s certificate in Psychiatric Mental Health Nursing from the University of Cincinnati and hold a Master of Science in Nursing with a focus in Clinical Nurse Specialist and Nursing Education from the University of Detroit Mercy.

I have experience working with children, adolescents, and adults from diverse backgrounds in outpatient, residential, correctional, and community-based settings. My areas of focus include depression, anxiety, ADHD, bipolar disorder, mood disorders, PTSD, schizophrenia and other psychotic disorders.

I believe mental health care should be collaborative, respectful, and individualized. My goal is to create a comfortable, nonjudgmental space where you feel heard, understand your treatment options, and feel empowered to take an active role in your mental health and overall well-being.

When anxiety, depression, ADHD, or shifting moods start affecting your relationships, your sleep, and how you feel about yourself, it can be hard to know where to start. I'm Moneak Parker, a Psychiatric Mental Health Nurse Practitioner in Michigan, working with adolescents and adults through psychiatric evaluations, medication management, and personalized treatment planning. I support clients with anxiety, depression, ADHD, bipolar disorder, borderline personality, OCD, PTSD, panic disorders, sleep concerns, anger, and substance use. My goal is a space where you feel heard, respected, and genuinely in charge of your own care.

Welcome to this courageous journey! If you’ve found your way here—even with hesitation or uncertainty—you’ve already taken a powerful first step: listening to the part of you that longs for healing, clarity, and growth. That alone is an act of strength. You don’t have to walk this path alone. I’m here to walk beside you—as a steady companion—through the valleys and the victories, the questions and the breakthroughs. Together, we’ll create space for your story, your healing, and your becoming.

I hold an MA and PhD in Counseling Psychology from Boston College and Indiana State University, where I received extensive training in multiculturalism and trauma-informed care. Over the past years, I’ve had the privilege of working in a variety of clinical settings—including university counseling centers and community mental health agencies—supporting individuals from all walks of life. I am a certified EMDR therapist and an approved consultant of the EMDRIA.

If you find it difficult to make sense of things and experience varying emotions as a result, come talk to me. Together, we will work on strategies, develop coping skills, and address the root causes of your difficulties and stresses.

I received my Bachelor’s in Social Work from Oakland University and my Master’s in Social Work from Madonna University. I have been a practicing social worker for four years, and during this time have received several certifications including: school social work, Trauma-Focused Cognitive Behavioral Therapy, and Cognitive Behavioral Intervention for Trauma in Schools. Based on my experience, I specialize in working with adolescents and children; however, I am confident in my education and ability to help clients of all ages.

I genuinely care about their journey and understand that healing isn’t always linear. I combine compassion with clinical expertise to help individuals feel understood, supported, and confident in reaching their goals. Whether we’re managing anxiety, mood changes, or life transitions, I’m here to walk alongside you at your own pace

When anxiety, panic, or grief starts running the show, it can be hard to remember what steady even feels like. For more than 15 years, I've worked with people during difficult seasons of life, helping them make sense of strong emotions and find steadier footing. I support people dealing with stress, anxiety and panic, depression, grief and loss, trauma and PTSD, and OCD. I also work with men who want a place to talk openly about what they're carrying, and with anyone navigating family conflict, anger, or questions of identity.
