Hello! My name is Cathy Randolph and I am a Board-Certified Mental Health Nurse Practitioner. I developed my passion for mental health during my journey working with veterans in residential PTSD and Substance abuse programs. My specialties include, but are not limited to treating and managing PTSD, Substance abuse, ADD/ADHD, anxiety, depression, mood disorders, and adjustment disorder. I am also a Medicinal Marijuana clinician.
Board-certified Psychiatric-Mental Health Nurse Practitioner (PMHNP-BC) and Family Nurse Practitioner (FNP-BC) Specializes in comprehensive psychiatric evaluations, medication management, and evidence-based psychotherapy for patients across the lifespan. Dedicated to providing compassionate, trauma-informed, and holistic care in both inpatient and outpatient settings.
With over 20 years of experience in clinical care, education, and research, I provide thoughtful, evidence-based psychiatry support tailored to high performing adults seeking clarity, stability, and wellness. My goal is to provide you both empathic and evidence-based support that leads to sustaining improvement.
I am a board-certified, Harvard-trained psychiatrist providing psychiatric evaluations, medication management and therapy to children, adolescents and adults. I treat a wide variety of mental illness, and I specialize in helping individuals with ADHD, depression, anxiety, autism and those who are gender-diverse or other LGBTQ+ individuals.
I work with adults who are experiencing depression and mood disorders, anxiety, trauma-related conditions, and substance use concerns. My approach integrates careful diagnostic evaluation with collaborative, evidence-based medication management, always considering the biological, psychological, and social factors that influence well-being.
I believe it’s important for patients to feel informed, respected, and supported. I have worked across hospital, emergency, outpatient, and forensic settings. All of these experiences have shaped a thoughtful, evidence based approach to assessment and treatment.
