Katie Johnson

Katie is a board-certified Psychiatric Mental Health Nurse Practitioner with more than 17 years of experience caring for individuals across a wide range of mental health settings. She began her nursing career on the inpatient psychiatric unit at Massachusetts General Hospital, where she spent eight years providing care to patients with acute psychiatric needs before relocating to Cape Cod with her family.

Since moving to the Cape, Katie has continued her dedication to mental health care through work in inpatient psychiatry, outpatient psychiatry, emergency services, home health, and crisis stabilization programs. Her experience across multiple levels of care has given her a strong understanding of both acute mental health crises and the long-term support needed for sustainable recovery.

Katie has developed a strong clinical focus on women's mental health, with particular emphasis on the emotional and psychological challenges that can arise during major life transitions, pregnancy, and the postpartum period. She works closely with individuals navigating pregnancy, postpartum adjustment, infertility-related stress, postpartum depression and anxiety, OCD, and the emotional challenges that can accompany new parenthood. She understands how overwhelming and isolating the postpartum period can feel and strives to provide compassionate, nonjudgmental support during this vulnerable stage of life.

In addition to peri/postpartum care, Katie has clinical interests in depression, anxiety disorders, and PTSD. She values treating the whole person rather than simply managing symptoms.

Katie uses a collaborative, shared decision-making approach with her clients, emphasizing the importance of a strong therapeutic relationship built on trust, empathy, and mutual respect. She believes that meaningful connection and individualized care lead to the best outcomes. Her treatment approach integrates evidence-based medication management with supportive psychotherapy, while thoughtfully considering each client's lifestyle, personal values, goals, and strengths.

She provides psychiatric evaluation, medication management, and brief psychotherapy for adults ages 18 and older.

Katie enjoys spending time with her family and attending her children's activities and events.
