I’m Mackenzie, a Psychiatric Nurse Practitioner dedicated to helping children, adolescents, and adults find balance, clarity, and confidence through compassionate, evidence-based care. I believe mental health treatment should feel personal, not clinical.
I am a board-certified Psychiatric Nurse Practitioner in Massachusetts. I offer comprehensive treatment combining medication with lifestyle and behavioral interventions. I help adult clients manage conditions such as depression, anxiety, OCD, bipolar disorder, psychotic disorders and substance use disorder. I also specialize in helping women navigate the peri and postpartum periods. I use evidence-based treatments that consider the client’s biological, psychological, spiritual, and social needs.
Dr. Gross graduated from Albert Einstein College of Medicine and completed an internship in pediatrics at Montefiore Medical Center. During this time, a rotation with the child psychiatry consultation-liaison team solidified his interest in psychiatry, particularly the intersection of medical care, family dynamics, and the social contexts that shape patients’ mental health. He completed his general psychiatry residency at the University of Miami, followed by a child and adolescent psychiatry fellowship at Johns Hopkins Hospital.
