    Craig Clark, MD

    Child, Adolescent and Adult Psychiatrist

    Chief Medical Officer, NNPA

    Craig Clark is a child, adolescent, and adult psychiatrist with nearly thirty years of experience as a clinician. He first attended West Virginia University as a Moore Chemistry Scholar and later Marshall University, from which he ultimately graduated college and medical school Magna Cum Laude.


    Drawn to Vanderbilt by the prospect of working with the famed neuropsychiatrist David Bear, M.D. Dr. Clark relocated to Nashville in 1988. There he completed his post-doctoral training, inclusive of a rotating internship, followed by a residency in adult psychiatry.


    Captivated by the idea of a developmental perspective on human health, and fortunate enough to gain mentorship from the then Chairman of Child Psychiatry Barry Nurcombe, M.D. Dr. Clark ultimately pursued a fellowship in child and adolescent psychiatry.


    Named Chief Fellow in Child Psychiatry his senior year, Dr. Clark developed a passion for teaching. He subsequently served in a supervisory capacity for Vanderbilt Child Fellowship Trainees for many years. He also enjoyed a number of years during which he traveled the country speaking to audiences of primarily fellow physicians on numerous topics in child, adolescent and adult psychiatry both in industry sponsored meetings and CME settings.


    For the more than twenty five years before founding NNPA, Dr. Clark was blessed to work in an invigorating relationship in private practice with his colleagues and friends as a partner at Associated Psychiatrists of Nashville. Between 1993 and 1995 Dr. Clark honed his skills in the most challenging of clinical circumstances, serving as Medical Director for all child and adolescent inpatient and outpatient services at Centennial Medical Center’s Parthenon Pavilion. He was the Tennessee Psychiatric Association’s Public Affairs Representative during the same period.


    Informed by his grandmother’s admonition to “Be the eternal sophomore” (Greek for “the knowledgeable fool”) Dr. Clark remains passionate about life-long learning and personal, as well as professional growth. In this vein he was one of the first child and adolescent psychiatrists in Nashville to offer neuromodulation (both neurofeedback and TMS) to his patients.


    Malcom Gladwell famously asserted mastery typically requires 10,000 hours of disciplined practice. With nearly 70,000 hours logged Dr. Clark still seeks to cultivate a beginner mentality, traveling regularly for continuing education opportunities. He is always on the lookout for any safe, effective treatments or technologies that might better serve his patients.


    When not roaming the halls of NNPA, Dr. Clark can be found spending time with his family, including his wife and co-founder/COO of NNPA Amy Powell Clark, as well as his three incredible sons. You might just also find him admiring art in all forms, or perhaps practicing what he preaches about the link between mental health and physical fitness while grinding out a match on the tennis court.

As such, parent training and sibling groups were amongst the work she co-facilitated.


    Since leaving Vanderbilt in 2002, Ms. Powell has been in private practice, first with Associated Psychiatrists of Nashville and now as the co-founder of NNPA. Ms. Powell works primarily with individuals suffering from the psychological and emotional consequences of trauma, OCD/anxiety, ADHD, social skills deficits, and mood disorders.


    A natural teacher, Ms. Powell has served in a supervisory capacity for graduate students from Vanderbilt, Lipscomb, and Trevecca who are completing pre-practicum and practicum-internships in clinical and counseling psychology and has done so for 20-years.


    Ms. Powell is a member of the Tennessee Psychological Association and American Psychological Association. She is a past board member of the Autism Society of Middle Tennessee.


    For Ms. Powell, witnessing the bravery of each individual who embarks on the journey to well-being and healing is truly an honor. She is inspired daily by the resilience of those with whom she works.


    While recognized foremost for her talents in psychotherapy, Ms. Powell is also a gifted figurative and portrait sculptor whose work has been recognized both locally and nationally. She was twice chosen for inclusion in the Scottsdale Artist's School "Best and Brightest" competition.


    In keeping with the NNPA philosophy of the inextricable link between physical and mental health, Amy is often found in her hours away form the office cultivating cardiovascular fitness by chasing her sons about Nashville and beyond. She also enjoys busting a move during the "dance party" breaks in weekly group therapy.
