Gabrielle Delarose, PMHNP

Staff Psychiatrist

Gabrielle Delarose is a dually boarded Psychiatric Mental Health and Family nurse practitioner with over ten years of clinical experience. Gabrielle is dedicated to providing culturally competent and evidence-based medication management and psychotherapy to assist individuals in achieving their goals to live their best life. I believe in holistic treatment of individuals, and focus on the individual’s overall well-being, including how they are functioning socially and professionally. In addition to medication and psychotherapy, she is a proponent of incorporating research-supported alternative modalities, including dietary changes, exercise, social interaction, and yoga. She also advocates of forest bathing (“shinrin-yoku”), a practice of spending time in nature that yields both medical and mental health benefits as discovered in research trials from around the world. As a professionally trained cellist, she also frequently incorporates art and music into appointments and treatment plans with patients. Her goal for all her patients is to improve all facets of a person’s life with treatment. Gabrielle is an LGBTQ+ affirming provider and has extensive experience working with diverse populations.

New patients should know that the initial appointment will consist of obtaining their social history in addition to their medical history. This is an important part of establishing a therapeutic relationship in addition to obtaining health information to use in formulating treatment plans. A person’s identity and life experiences are a significant influence on a person’s health and well-being, and Gabrielle believes in discussing these experiences in order to best understand a patient’s background and incorporate that into their care. Patients are encouraged to write down any questions they may have prior to the appointment, as well as any significant points they want to discuss. This is encouraged because, as patients, we may forget to address these points without a prompt from the provider. Gabrielle also encourages patients to actively participate in their care and firmly believes in a patient’s right to autonomy and agency. This patient-centered approach empowers patients to help guide treatment plans that best fit the patient’s needs and abilities at any given time. Patients are also encouraged to discuss any concerns about medications or treatment, particularly if there are concerns about side effects.

Gabrielle works collaboratively with patients to determine appropriate and preferred treatment plans, including medication and therapy. She uses cognitive behavioral therapy (CBT) as the primary therapy modality, in conjunction with existential therapy, depending on the patient’s needs and preferences. She prefers to allow patients flexibility in their treatment, so the process may look less structured depending on the immediate needs of the patient. Other times, particularly while working through a specific problem in therapy, appointment agendas may be planned out for several weeks. If at any time, however, a need arises to deviate from preplanned appointment agenda, patients are encouraged to discuss this at the beginning of the appointment. Above all, patients’ needs will guide the agenda.
