A Message From Our Co-Founder
Dr. Itzel Harriott
PharmD, PhD, RMHCI · Co-Founder & CEO
The Clinical Mental Health Green Book, LLC is committed to being a trusted, high-standard resource in clinical mental health counseling education and practice. Our mission is to provide comprehensive, accessible, and effective training and quick reference materials — designed to enhance learning and challenge the preparation of aspiring, practicing, and veteran mental health professionals.
We strive to elevate the training experience by integrating feedback from individuals at every stage of their career journey — whether they are just entering the field, actively practicing, or sunsetting their professional roles. Our team — led by myself and Jerome McDuffie (Executive Director) — includes Counseling Educators, Qualified Supervisors, LMHCs, LPCs, RMHCIs, Student Interns, and Substance and Addictions Professionals. Every product is developed, reviewed, and refined by this collective, ensuring a highly comprehensive, must-have resource for anyone preparing for the NCMHCE.
"A key element of our mission is inclusivity — particularly for underrepresented and marginalized communities."
Through innovative tools like our Green Book Toolkit with Thesaurus, we address gaps in familiarity with clinical terminology used in exams and practice. This thesaurus serves not only as a study tool, but also as a valuable resource in clinical settings — helping practitioners translate complex terms into language their clients can understand. This approach has been particularly praised by minority clinicians and supervisors who use it to bridge communication gaps and enhance client comprehension in medical and therapeutic contexts.
If you're preparing for the NCMHCE, I recommend starting with our two must-have volumes: Volume I (Psychotherapist Toolkit) provides the essential exam strategy, Edge Mapping framework, clinical thinking structure, and terminology alignment — it sets the foundation for how to approach every clinical scenario. Volume II (NCMHCE Study Guide) delivers 300 practice questions with 9 unique differentiating vignettes to confirm your readiness and identify remaining gaps. Volumes III through IX are specialty volumes designed to deepen your understanding in specific clinical areas where more insight is needed.
Our overarching goal is to aid society in producing highly competent, empathetic, and culturally attuned therapists — including those from underrepresented communities — who are prepared to succeed in the National Clinical Mental Health Counselors Exam and beyond. By continually listening to feedback, refining our materials, and focusing on the needs of learners from diverse backgrounds, we work to improve pass rates, support supervisors with top-tier resources, and set the standard for clinical mental health training and education.
The Clinical Mental Health Green Book is not just a study aid — it's a partner in your professional journey, dedicated to shaping a stronger, more inclusive field of mental health care.
With warmth and purpose, Dr. Itzel Harriott — Co-Founder & CEO, The Clinical Mental Health Green Book, LLC
