Brooke Heyman, ARNP, PMHNP


I am a board certified Psychiatric-Mental Health Nurse Practitioner with a Master of Science degree in Psychiatric-Mental Health Nursing from New York University. I completed my clinical training in psychiatry with children, adolescents, and adults at NYU Langone Medical Center, NYU Student Health Center, and in private practice in New York City. I also hold a specialization in Advanced Practice Holistic Nursing from New York University, with a focus on Integrative and Holistic Psychiatry. I have a particular interest in mindfulness-based cognitive therapy, nutritional neuroscience, and functional medicine, and was recognized for my commitment to innovation in mental health and mind-body medicine as NYU College of Nursing’s Distinguished Master’s Student and Distinguished Student in Holistic Nursing. Prior to my graduate training, I worked as a psychiatric registered nurse, primarily with homeless adults struggling with substance use and severe mental and physical health issues. I believe that honoring each individual’s unique experience fosters an environment that promotes personal growth and recovery. 

my practice

I work with children, adolescents, adults, and older adults, ages 12 and older. I perform comprehensive psychiatric diagnostic assessments and collaborate with clients and their families to create a personalized treatment plan based on each client’s needs, goals, and preferences.  While I practice conventional psychiatry, I approach mental health treatment in a holistic manner that addresses the physical, environmental, emotional, and spiritual aspects of health. I strongly emphasize the importance of lifestyle factors, including self-care, nutrition, sleep, and stress management. Treatment can include medication, short-term supportive psychotherapy, behavior modification, and a variety of complementary approaches, including nutraceutical therapies, targeted dietary intervention, and mindfulness training. As an integrative practitioner, I also consider aspects of health that are often overlooked in traditional psychiatry, including nutritional status and gastrointestinal health. My experience and practice includes, but is not limited to, the treatment of: ADHD, depression, anxiety and panic disorders, bipolar spectrum disorders, obsessive-compulsive disorder, insomnia, adjustment disorders and life transitions, stress-related disorders, psychotic symptoms, somatic symptom disorders, autism spectrum disorders, gender dysphoria, trauma, behavioral issues, and interpersonal difficulties. 


I am dedicated to creating a supportive and non-judgmental environment that nurtures each client’s potential for optimal health and happiness. I believe that the most effective treatment is personalized treatment, which is based upon a genuine understanding of each client’s individual experience, history, and personal values. With this knowledge, I aim to partner with the client to establish a treatment plan that holistically addresses their unique needs, both for short-term symptom management and for long-term change.
